REV. C 06/18/02 4-2

The METSO ST356 is a hydraulically operated portable screening plant capable of producing a wide range ofproduct sizes. The two bearing, two deck screen box can be equipped with various screen size combinations toproduce sized product down to 1 mm while maintaining high productivity levels.

Raw material is fed onto a variable speed belt feeder through a tapered grid deck, which rejects oversizedmaterial. The feeder belt delivers the material onto the main conveyor and then to the screen box whereseparation and sizing takes places.

The separated products are stockpiled via a product conveyor and two side conveyors

4-2-1 MATERIALS MACHINE IS CAPABLE OF PROCESSING

The ST356 can be used for screening and sizing the following materials:

• Sand • Clay

• Gravel • Iron ore

• Granite • Top soil

• Limestone • Slag

• Sandstone • Concrete Debris

• Coal • Grain

For screening requirement not listed above, contact your authorized METSO Distributor for assistance.

Note:

The performance of the ST356 can vary depending on the type andmoisture content of the raw feed material. It may be required that youcontact your local authorized Metso distributor for guidance on yourspecific application.


REV. C 06/18/02 4-3

4-3-1 SITE PREPARATION

Proper site preparation and machine placement will provide a safe, efficient atmosphere conducive to highproductivity. The following site preparations procedures are recommended:

• Select an area with adequate clearance around the machine

• Place the METSO ST356 as close to the raw material stockpile as possible

• Position the machine on a firm, level foundation

• Ensure that no hazards to operation are present

The ST356 is designed to be supported on the hydraulic hopper support legs. It is recommended that the ST356be level in both longitudinal and lateral planes.

4-3-2 OPERATING TECHNIQUES

To achieve maximum efficiency and production from the ST356, a number of factors should be considered:

• Screen size

• Screen angle

• Feeder belt speed adjustment

• Main conveyor diverter plate adjustment

• Main conveyor height above screen

• Overs side conveyor speed adjustment


REV. C 06/18/02 4-4

4-4-1 SCREEN MESH SELECTION

Selecting the proper screen media, type and appature is the most important factor influencing productionefficiency. Choosing the correct screen size can influence production output by as much as 50%.

If the majority of product is sliding off the top deck, a larger top deck opening should be considered. This isespecially true for sticky material such as clay and wet topsoil. However, a top deck screen size that is too largefor the bottom deck size will cause a similar situation at the second deck where an excessive amount of desiredproduct fails to pass through the bottom screen. The usual method of choosing screen sizes is to select thebottom screen opening based on final size requirements and then choose a top screen that adequately protectsthe bottom deck while not allowing excessive runoff.

As a means of example refer to the following illustration.

If production problems are encountered and an alternate screen combination is believed to be required, contactyour local authorized METSO Distributor.

4-4-2 SCREEN SPEED

The screen speed of the ST356 is factory set. Adjustment may be required overtime. See: Section 6 of thismanual. Overloading can cause a reduction in screen speed. If the screen is not overloaded and a reduction inscreen speed is noticed, the screen has experienced either a hydraulic or mechanical malfunction, which shouldbe corrected immediately. Over-speed can cause structural fatigue and damage. See: Section 6 for correctoperational speeds.

NOTE : When hydraulic fluid reaches normal operating temperature, there may be a fluctuation inscreen speed of 50-100 rpm.

REV. C 06/18/02 4-5

4-5-1 SCREEN ANGLE SELECTION

Proper screen angle is determined by the nature of the material being screened and the size of the screensbeing used. Steeper screen angles minimize the amount of time the material spends on the screen. A materialthat requires more time on the screen to separate will require a shallower screen angle than a material, such asdry sand or loose gravel, which separates easily. Square mesh screens generally require a shallower screenangle than a slotted screen. A harp wire screen requires a very steep angle. Choosing the correct screen anglecan greatly improve production.

The screen angle of the METSO ST356 is adjustable from 15 to 25 degrees. As a general rule, the followingscreen angles are recommended for the listed square aperture size:

APERTURE SCREEN ANGLE

-3/4” 25 deg.

+3/4” - 3” 20 deg.

+2” -3” 15 deg.

Slotted wire generally requires a steep screen angle (20 degrees or greater) depending on the nature of thematerial to be screened.

Harp wire requires a very steep angle, generally 25 degrees to achieve high production rates. Harp wirescreens “cut” through material, acting more like knife-edges than a screen, hence the need for steep screenangles.

NOTE: Changing the screen angle requires removal of trestle pins and adjustment of trestles. (Refer toSection 4, Operations for adjustment details).

4-6-1 DIVERTER PLATE ADJUSTMENT

The diverter plate should be adjusted to distribute the material across the full width of the feed box just before itreaches the screen. This adjustment permits full use of the available screen area while distributing the materialacross the full width of the screen box.

Diverter plate adjustments are necessary when:

• The screen angle is adjusted.

• Main conveyor angle is adjusted

• Minor adjustments to improve screening capacity.

Whenever the screen angle or main conveyor is adjusted, the diverter plate position should be checked. If thescreen angle is adjusted to a very low angle it may be necessary to lower the feed plate to the low position. Alladjustments are made at the diverter plate mount.

NOTE: Changing screen angle requires checking adjustment of diverter plate. Refer to Section 4,Operations for adjustment details.


REV. C 06/18/02 4-7

4-7-1 SHREDDER-HAMMERMILL APPLICATIONS

The METSO ST356 may be equipped with an optional hammermill type shredder which is used to processagglomerations of topsoil, peat and similar material. The shredder-hammermill is equipped with a variablespeed drive feature enabling the operator to match the shredder-hammermill shaft speed to the characteristicsof material being screened.

To produce a fine grade of material:

• Increase shredder-hammermill shaft speed to maximum.

• Decrease feed belt speed to optimize efficiency.

To produce a coarse grade of material:

• Decrease shredder-hammermill shaft speed

• Increase feeder belt speed to flood the shredder-hammermill chamber with material.

When the shredder-hammermill is not required the shaft must be stopped and the assembly lifted and stowedvia the supplied lift cylinder chain (for a single shaft shredder) or the shredder lift trestle assembly (for the dualshaft shredder). (Refer to Section 4, Operations ).

DANGER: SHREDDER-HAMMERMILL SHOULD NEVER BE RUN IN THE RAISED POSITION AS EXTREMEDANGER WILL RESULT TO THE OPERATOR OR PERSONS NEARBY FROM MATERIALEXITING FROM THE SHREDDER-HAMMERMILL CHAMBER.

IMPORTANT: DO NOT RUN THE SHREDDER-HAMMERMILL WHEN PROCESSING STONE OR SAND ASEXCESSIVE WEAR TO THE HAMMERS AND INTERNAL ROTATING MEMBERS WILLRESULT.


REV. C 06/18/02 4-8

4-8-1 EFFICIENT LOADING OF THE HOPPER/GRID

There are a few considerations to keep in mind when feeding material onto the hopper/Grid section of theMETSO ST356.

To avoid damage to the hopper section, material should never be dropped from a high bucket angle onto theGrid section. Material should be “rolled” onto the Grid section from as low an angle as possible allowing thematerial to slide off the hopper feed plate and across the Grid section for classification.

4-8-2 REMOVING GRID TAILINGS

The oversized material from the Grid bars should not be allowed to accumulate above the underside of thefeeder belt guard doors. To remove, push the tailings with the loader by coming along side of the ST356.

Do not charge the ST356 broadside, using the ST356 as a backstop.

9. After the engine has been operating and warmed up for a few minutes, check around the enginecompartment area for engine oil, fuel, coolant or hydraulic fluid leaks.

10. Check the engine control panel indicators for normal operation. If operation is not normal, stop the engineand determine the cause.

11. Set manual throttle to the operational speed position.Before moving the machine refer to sections “5-22-1 RADIO REMOTE OPERATION and 5-28-1LOAD/UNLOAD INSTRUCTIONS ” of this manual.

For screening operations refer to the following sections of “5-5-1 ENGAGING HYDRAULICS”.


Rev. C 06/18/02 5-5

5-5-1 ENGAGING HYDRAULICS

The details of operation for each of the hydraulic control levers are listed on the following pages. The operatormust be knowledgeable in the operation of all controls before engaging any hydraulics. Some hydraulicfunctions require additional actions to be performed, such as removing safety pins or lowering guards, beforeengaging.

Normal sequence of operations: (1.) Engage the product and side conveyors, (2,) Screen-box, (3) Mainconveyor and feeder conveyor. Conversely ALL conveyors should be run until empty then stopped in reverseorder (3,2,1,). If equipped with a shredder, additional considerations must be made.

IMPORTANT: INCORRECT SEQUENCING OF HYDRAULIC OPERATIONS CAN RESULT IN JAMMING THECONVEYORS AND MAY DAMAGE THE MACHINE.

Startup/Shutdown

The following procedures assume the Nordberg ST356 is equipped with a shredder.

The shredder, is a single shaft, single speed unit, which was designed to only be used as an aid to materialseparation for the screen media. The intended use of shredder is to break up light conglomerated soils. Heavygravel and aggregates will severely shorten the life expectancy of the Hammers/Blades. The shredder issecured in the raised (non-operational position) by safety chains, and lowered to the operational position fortransport and operation.

5-5-2 HYDRAULIC STARTUP PROCEDURE The following procedures assume the Nordberg ST356 is equipped with a shredder.

( * ) Omit these steps if shredder is not installed. See: Page 4-15 for shredder operation procedures ifequipped.

Before startup, ensure all items stored for transport are removed from the hopper and conveyors are clear.1. Familiarize yourself with the location of the (3) Yellow and Red EMERGENCY SHUTDOWN buttons2. Ensure all hydraulic control levers and switches are in the stop/off position.3. Turn FEEDER BELT SPEED CONTROL knob to -O- position (clockwise).4. * Ensure the SHREDDER CONTROL levers are in the stop position.5. Start the engine. (Refer to page 4-2 for detailed procedure).6. * Raise shredder to non-operating position using SHREDDER RAISE/LOWER hydraulics.7. * Secure shredder in the non-operating position using the securing devices.8. Move TAIL/SIDE CONVEYOR hydraulic control switch to ON position.9. Move SCREEN hydraulic control switch to the ON position.10. Move MAIN CONVEYOR/FEEDER hydraulic control switch to the on position. 11. Turn FEEDER BELT SPEED CONTROL knob counter clockwise to start feeder belt.12. Perform the daily operational checks. (Refer to 5-5-1)13. To achieve maximum efficiency and productivity from the ST356, a number of factors should be considered:

• screen angleadjustments

• side belt adjustments

• feeder belt speedadjustments

• main belt adjustment

• product belt adjustment


Rev. C 06/18/02 5-6

5-6-1 DAILY OPERATIONAL CHECKS

Some operational checks can be performed only after engaging hydraulics. They are listed below because theymust be performed on a daily basis in addition to the daily pre-start checks.

Note: Failure to perform these checks may result in premature equipment failure.

• Emergency stop system.

• Tipping grid manual and remote operation functioning properly

• Product and Side conveyors straight at hinge points

• Feeder, main, product and side conveyor belts are tracking straight.

• Guards and skirting rubber adjusted and in place

• Vibration of screen box, sub-frame (if excessive vibration occurs, shut down and source the cause).

• Listen for unusual noises on all moving components. (Bearing growl, metal scraping).

• Check for Hydraulic leaks.

5-6-2 SHUTDOWN PROCEDURE

(*) The shredder is optional. Omit these steps if shredder is not installed.

1. Clear debris from GRID BARS.

2. Allow feeder belt to run until hopper is clear of material.

3. * Move SHREDDER hydraulic control lever to the STOP position.

4. * Raise shredder using SHREDDER RAISE/LOWER lever.

DANGER: NEVER RAISE THE SHREDDER WHEN IT IS RUNNING AS EXTREME DANGER WILLRESULT TO THE OPERATOR OR PERSONS NEARBY FROM MATERIAL EXITING FROM THESHREDDER CHAMBER.

5. Let feeder run out and then turn the FEEDER BELT SPEED CONTROL knob to -O- position (anti-clockwise).

6. Allow main conveyor to run out the material. Move MAIN CONVEYOR / FEEDER hydraulic control switch tothe OFF position.

7. Allow screen box to run until clear of material. Move SCREEN hydraulic control switch to the OFF position.

8. Allow product conveyor and side conveyors to run until clear of material. Move SIDE/PRODUCTCONVEYOR hydraulic control switch to the OFFposition.

9. Idle engine down, allow cool down time.

10. Turn the engine control panel key switch to the OFF (0) position to shut down the engine.

11. Remove the key, close and lock the engine compartment door whenever the machine is left unattended.

6-3-1 SCREENING PREPARATION (continued)

Motion / TransportThe ST356 must be partially folded or unfolded, depending on starting condition, to be moved or loadedfor transport. Failure to do so will result in damage to the machine.

READ THE COMPLETE DETAILED MOTION INSTRUCTIONS FOUND INSECTION 5-19-1 MOTION INSTRUCTIONS.The following is a brief synopsis of the conditions that have to be met before moving the machine. Find andcheck the radio remote. Understand the function buttons before proceeding. Detail of the remote will be found inSection 5-13-1 1. Unfold the side conveyors to provide 100mm of clearance from the support.

2. Lower the side conveyors to provide 100mm of side clearance from the support.

3. Raise the Main conveyor / screen to the first exposed hole ONLY.

4. Raise the hopper support legs fully.

5. Place the toggle switch on the main control to radio.

6. Increase the throttle to a position between 1/2 and 3/4. Engine RPMs may be used to regulate track speed.

7. Safety first. Slow and easy control motions. Keep personnel away from the moving machine. Watch for tailswing clearances. Watch for over head obstructions. Stand well clear, the life you save may be your own.

Checks and AdjustmentsMake the following checks and adjustments in preparation for screening operations:

• Check to ensure the ST356 is fully assembled, components are resting on their support pins, and clips areinstalled and the hydraulic rams are under no pressure.

• Check that main conveyor and hopper are empty of screens or other accessories before start-up.

• Ensure the hopper support legs are down and set.

• Check to see if proper screen selection is in the screen box.

• Check that the entire screen mounting hardware is tight.

• Perform Daily Pre-Start Check. Start-up instructions. And Daily Operational Checks Refer to Section 5 Operations.

The general nature of material screening would be considered by definition as: EXTREME OPERATINGCONDITIONS. Therefore, extra care and concerns should be placed upon air circulation for engine andhydraulic cooling radiators engine air filtration, maintenance scheduling, material buildup around head and taildrum areas.A cleaning and checking routine to fit your particular application will help reduce failures and unnecessary downtime.Due to vibrations over time components may become loose, simple routine checks and corrections, such aschecking and tightening the band clamps on the engine air intake tubes, may reduce the chances of majordamages.

NOTE:

TURBO CHARGED ENGINES WILL DRAW AIR IN FROM THE SLIGHTEST OPENING AS AIR FILTERSBECOME DIRTY AND RESTRICTED ROUTINE CHECKS OF ALL TUBE CONNECTIONS AND FILTERCONDITIONS ARE REQUIRED.

SET-UP for operation

The following operation requires the two Grid sub-framesupports to be installed together. These are located ateach side of the back of the hopper. 1. Remove support pins from lower end of both

the grid sub-frame supports. Install thegrid deck sub-frame pins into the grid/sub-frame locking holes at each side of thehopper. This locks the twocomponents together (grid sub-frame and grid deck) enablingthe use of the grid lift ram toraise the sub-frame intothe operating position.

2. Using the gridraise/lower switch onthe engine controlbox only, move theswitch to the raiseposition.

3. Align the holes of thegrid supports withthe support anchor mount and insert the pin.

Use caution when toggling the grid raise/lower switch, as there is a delay in the system.4. Lower the grid/ sub-frame assembly

and remove the locking pins. Thegrid deck will now moveindependently from the sub-frame.

5. Check the cycle time of the tippinggrid using the remote control. If thegrid does not move or does not fullycycle the time adjustments need tobe corrected. See: 8-13-1 fordetails. The tipping grid is ready fornormal operation.

LOWER for transport1. Install the grid deck / sub-frame lock

pins into the both sides of the GRID/SUB-FRAME locking holes. This locks the twocomponents together to use the grid lift ram tolower the grid deck assembly to the transportposition.

2. Using the grid raise/lower switch on the enginecontrol box only, slightly toggle the switch to the raise position only enough to relieve the pressure off of thesub-frame support anchor mount pins.

3. Remove the support pins.4. Using the grid raise/lower switch on the engine control box only, toggle the switch to the lower position until

the grid/sub-frame assembly is at the lowest point. 5. Replace the support pins into the sub-frame supports for future use.

7-4-1 Site Preparation

WHEN THE ST356 IS DELIVERED, OR WHENEVER IT MUST BE MOVED, EVEN IF ONLY TO A DIFFERENTLOCATION AT THE SAME SITE, A NUMBER OF ITEMS MUST BE CONSIDERED BEFORE THEMOVE OCCURS.

Site planning includes:

• Selecting a firm, level location.

A firm site is essential, as the ST356 operation weight may exceed 90,000 lbs. (40,800kg).

The site must be firm and level in order that the hopper is adequately supported on the hopper supportlegs. It may be required that steel plates or wooded blocking are placed under the feet of the hoppersupports

Levelness is critical to the tracking and loading of the conveyor belts.

• Selecting a location with enough open space around the machine so that it can be safely operated.

Easy access to material piles and visibility of other machines and personnel will improve safety andefficiency.

• Position the ST356 for the most efficient loading.

Initial set-up in a good location, close to the material to be processed and easy access to removeprocessed material, will provide improved production. The mobility of the ST356 is a great advantage,however, as processed material accumulates around the machine, moving the ST356 requires movingthe material in order to move the machine.

• Check that no hazards to operation are present.

Check for operating site hazards such as: Over head power lines, Over head conveying equipment,under ground electrical, gas or water systems.

CAUTION: KEEP ALL PERSONNEL AT A SAFE DISTANCE FROM THE ST356 WHEN IT IS BEING RAISED,LOWERED OR MOVED.

Grease fittings are color coded Red - Grease weekly.Note: Annually remove the bearing caps, clean out the old grease and refill. The bearings should be 30% to 50% full, over filling will cause overheating and bearing failure.

8-5-4 PILLOW BLOCK BEARINGSNote: The general ST356 applications for these bearings indicates that re-greasing is not necessary. Inthis application re-greasing will most likely shorten the bearing life.Self-Lube bearing are factory charged with the correct amount of grease and do not require a further greasecharge when being fitted. Relubrication is not normally necessary except when operating at extremes oftemperature, speed, loading, extended running or where excessive wet or dirty conditions exist. The re-greasingcycle is dependent upon each application. All cast iron units are fitted with a standard re-greasable bearinginsert. The housings are provided with a tapped hole to facilitate re-lubrication and supplied with a plastic pluginserted into the tapped hole. All such units are tapped ¼” UNF. To make the unit re-greasable, remove theplastic plug and substitute with a grease nipple. Avoid over-greasing!


MAINTENANCE

REV. C 06/18/02 8-6

8-6-1 ENGINE OIL VISCOSITY

As the viscosity of lubrication oil is greatly influenced by the temperature, the choice of SAE grade should begoverned by the ambient temperature at engine site. Optimum operating behavior will be attained if you take asguide the oil viscosity diagram below.

Should temperatures temporarily fall below the limits of the SAE grade selected, this will merely affect thestarting performance but cause no damage to the engine. Exceeding the application limits should not be over aprolonged period, in order to keep wear down to a minimum. Oil changes dictated by the time of year can beavoided by using multi-grade oils. Multi-grade oils - particularly light-flowing oils also tend to reduce fuelconsumption.

8-6-2 ENGINE MAINTENANCE

REFER TO THE DEUTZ OPERATION MANUAL FOR YOUR SPECIFIC ENGINE.

CAUTION: WHEN CARRYING OUT ANY FORM OF MAINTENANCE OR REPAIR ALWAYS ENSURE THATTHE ENGINE IS STOPPED AND THE IGNITION KEY IS REMOVED AND STORED IN A SAFEPLACE.

8-6-3 CHECK ENGINE OIL LEVEL

1. Check engine oil level on dipstick daily.

2. Add oil if oil level is below the add mark on dipstick.

NOTE: Do not operate engine when oil level is below the add mark. Oil levels anywhere within thecrosshatch on dipstick are considered acceptable to operate engine.

8-6-4 REPLACE ENGINE OIL AND FILTER

Replace after first 50 hours, Intervals of 250 hours there after are recommended.

Testing of Hydraulic oil samples taken at 500 hour intervals are a good way to insurethe condition of the oil and may increase change intervals and reduce operating costs. Most reputable oildealers offer this service and will have sample kits available upon request.

Note: Use a suitable container to drain the hydraulic oil into taking care not to spill it. Oil is hazardousto the environment.

Note: Fill to the approximately one half to three quarters as indicated by the sight glass when chassis islevel.

When the ST356is resting on the ground (working position) the level will appear less than when chassisis level.

8-14-1 CONVEYOR COMMON OCCURANCES

The following is a brief description of conveyor belt problems with possible corrections. The following pages willoutline the adjusting procedures for these common problems. Any mis-alignments should be corrected beforeoperating the machine. For further detailed troubleshooting see page 8-18.

Oblique travel

Insufficient alignment of pulleys and idlers

Mis-alignment of carrying idlers

Material build-up on head, tail drums and Idlers.

Check belt cleaners and replace if necessary.

Wet patches on the pulley side of the belt due to rain or snow (causes friction variations between the beltand drums and Idlers.)

Side influences due to high winds

Oblique joining of the belt

Inspection almost always shows minor obliquities in the joint, but seldom results in oblique travel of theentire belt mainly it is limited to the jointed section.

Belt tracking

Belt tracking off to one side or diagonally.

Many conditions could affect this problem. Carrying idlers have little affect on an empty belt, the headand tail drum have a greater steering affect on an empty belt. Carrying idlers will have a significantaffect with a loaded belt as the belt crosses over a mis- adjusted idler. Return roller mis-alignment willaffect a loaded or empty belt equally. Loaded and empty conveyors will react different under suchconditions.

Uneven heating of the belt during sun rise, allow the belt to run in for a period before readjusting.

High wind conditions, empty or lightly loaded conveyors with exposed sides are especially vulnerable towind conditions.

Mis-aligned tail drum.

The tail drum belt scraper tension is too tight.

The conveyor belt has not been loaded evenly

Machine is not sufficiently level.

Obstructions caught in the wing type tail drum giving and artificial adjustment to the belt.

Material buildup on rollers. Gives the roller or idler different circumferences which will direct the beltaway from the larger diameter of the roller.

Head or tail drum bearing failure.

Conveyor frame is twisted or horizontally racked.Note: The following conveyor belt maintenance section offers many solutions to the different problemsencountered.

8-15-1 TROUGHED CONVEYOR MAINTENANCE

1. Check to ensure that all conveyor guards are in place.

2. Check the belt is free from obstructions or foreign articles.

3. Check the condition of the belt.

4. Check that the belt is running straight and that it is correctly tensioned.

5. Check that all return rollers are straight (90° right angle to the frame)

6. Check end drum bearings for wear or damage and replace as necessary.

7. Check end drums for wear or damage and replace as necessary.

8. Check that all rollers are free from material build up, and running freely.

9. Replace any rollers with defective bearings.

10. Clean all debris around the tail drum and keep this area clear.

11. Check the head drum belt scraper and screen feed plate and adjust as required.

12. Check the tail drum belt scraper and return belt scraper and adjust as required.

13. Check for all rubber skirting and adjust as required.

8-14-2 TROUGHED CONVEYOR BELT OBLIQUE ALIGNMENT

Oblique travel caused by insufficient aligning of the rollers may cause a fast deterioration of the conveyor belt.

1. Align all end drums, rollers and return rollers at 90° right angles to the frame.

2. Check that all end drums and rollers are level to each other. Adjustment is made as indicated below byturning the troughed idlers and rollers in the direction of the arrow, until the belt is running straight andcentered on the conveyor.

3. Also return rollers may cause oblique belt travel, and therefore they must be aligned at right angles toframe, and after that adjustment can be made.

4. Check conveyor frame folding mechanisms for proper alignment and tightness of fit.

8-16-1 TROUGHED CONVEYOR BELT TRACKING ALIGNMENT

If the conveyor belt runs off the center line, then the direction of the belt wander determines in which directionthe adjusters have to be adjusted.

Side conveyors adjusting bolts tend to move during transport. Tail drum alignment may be necessary uponunfolding. Tail drums must be at 90° right angle to the frame and aligned with the head drum for properoperation.

To adjust the belt for running off center line, proceed as follows (see figure below):

1. Level the machine.

2. Run the machine to determine the direction of belt wander.

3. Stop the machine.

4. Open the access guard door, (if required.)

5. Tail drum bearing bolts should only be snug, to allow bearing to be adjusted. Loosen tail drum bearing boltsif necessary.

6. Tension the adjuster on one side and slacken the adjuster on the other side.

7. Close the guard door.

8. Start the machine.

9. Repeat steps 1 to 8 until the belt runs straight.

10. Tail drum bolts should be only snug after final adjustment is made.

11. Check belt tension.

8-17-1 CONVEYOR BELT TENSIONING

Tension should be measured at the middle of the return side of belt along the centerline.

Deflection should not be less than about 2½ inches.NOTE: Over-tensioning will cause bearing failure and belt fatigue. Under tensioned belting will causespillage and head drum slippage.

Belt tensioning requires that both adjusters be tensioned equally.

1. Tail drum bolts should only be snug, Loosen tail drum bearing bolts slightly if necessary.

2. Adjust both sides of the tail drum equally.

3. Check belt deflection at the middle of the return side of belt along the centerline.

Deflection should not be less than about 2½ inches.4. Snug the tail drum bearing bolts after final adjustment is complete (if necessary).

Note: The tail drum bearing bolts are generally left only snug to allow free movement of the bearing onthe frame for tension purposes. Tightening of the tail drum bearings to lock the tail drum position, afteradjustment, is acceptable.

8-20-1 SCREEN BOX SPEED ADJUSTMENT

The screen box speed adjustment is a simple process; however, very critical for proper operation. Note: All operating functions are to be performed at set maximum throttle.The screen box speed adjustment is as follows:

1. With the engine off install reflective tape on the screen box shaft end located on the non motor side of thescreen box.

2. Install reflective tape on the engine harmonic balance. NOTE: Remove any other reflective markings to ensure accuracy.3. Start engine and run engine up to full preset stop.

4. Check engine RPMs. at full throttle preset stop. The engine must be running at 2100 rpms under a no loadcondition. If it is not, STOP and proceed to section 8-19-1 Throttle set and set the engine speed accordingto the instructions.

5. Engage the screen. Note the reading.

6. Check screen box shaft speed. Note the rpm.

7. Screen speed should be set to 950 ± 25 rpm (warm).

NOTE: "Warm" means oil is approximately 50° C or 122° F.. Warm oil will give an accurate reading. Coldoil will tend to run the screen shaft at a higher rpm and hot oil generally a lower rpm will beregistered.

8. Check engine rpm. Adjust if necessary to the proper setting of 2100 rpms. See: 8-19-1 Throttle setting.Note the reading. DO NOT EXCEED MAXIMUM ENGINE SPEED OF 2100 RPMs UNDER A NO LOADCONDITION.

9. Screen shaft speedis set at theDanfoss valve.The screen sectionis the secondsection from thebottom. There are2 set screws withlock nuts, the lefthand set screwadjusts the screenspeed. Check

shaft rpm with theoil warmed up (50deg c +). Shaftspeed should be950 rpm. A slightturn of the screwmakes a largedifference in shaft speed. Turning the set screw in decreases the screen shaft speed. Tuout increases the speed.

10. Check speed after tightening lock nut, speed can change. Some oil will weep out from unwhen loose.

1. Start and run the engine at idle, to carry out the following steps.

2. Unfold both wing conveyors and product conveyor to the operation position.

3. Raise the Main Conveyor to its highest position and lock in place using the Pin and “R” Clip

4. Remove all debris from the Top Deck Mesh and any debris around the Material Distributor Plate locatedat the end of the Main Conveyor. If Walkways are not fitted then care must be taken when trying toaccess the Screen from the sides. It is recommended that you work from a ladder that is suitablysecured.

5. If the meshes are badly covered with sticky material it is recommended that the Screen Box be runempty for at least 10mins. After this switch off the unit and remove the key. Inspect the meshes and ifthey are still badly covered then tap the meshes with a hammer loosening the sticky material. Repeatthese procedures until you are satisfied that all material is removed.

6. Raise the Screen / Product Conveyor assembly so that the lift-ram securing pins can be removed. Storepins in a safe place.

7. Lower the Screen / Product Conveyor assembly so that the Product Conveyor is in the horizontalposition and resting on the chassis member. Lower the assembly enough so that the connecting trestlebears no load and the pins are loose.

Note: If replacing Top Deck meshes only, follow steps 1-7 before mesh removal. There is no need toseparate the trestle. Allow the Screen / Product Conveyor assembly to be lowered completely ensuringthe Screen Sub-Frame assembly is lowered onto the Chassis frame.

8. Remove trestle pins and store in a safe place.

9. Raise the Screen assembly to its lowest pin position, separating the product conveyor trestle assembly,and replace the lift ram securing pins.

10. If your Nordberg ST356 is fitted with Hydraulic Screen tensioning then ensure that the system isworking correctly before changing the meshes.

11. Switch off engine and remove the ignition key. Keep ignition key in your pocket at all times whenworking on the unit. For extra safety, it is advised that all E-Stops are depressed while working on theScreen.

12. Metso Minerals recommends that prior to the removal of the meshes from the Screen, the replacementmesh, replacement Capping rubbers and Cable Ties are on site.

13. Prior to replacement, thoroughly clean down side plates of the Screen Box.

14. Remove all debris at the points where the Screen mesh hooks into the cross beams.

15. Always inspect the condition of Screen Tension Bolts, Screen Sealing Strips and Clamp Plates duringmesh replacement. Replace damaged or worn parts accordingly.

16. Replace all damaged Capping rubbers and cable ties

17. Replace any damaged bolts / nuts / washers etc.

18. Replace / repair any damaged or worn Screen Sealing Strips.

long series nuts fitted. Slacken off all M20 Bolts, ensuring that no damage is caused to the threads.

2. remove all M20 nuts and store in a safe place.

3. Carefully remove the M20 bolts being careful not to damage the threads. It may be required that you knockout the bolts using a heavy piece of timber. Store in a safe place.

Special note:If the clamp plates on your machine are fitted with the 2 x M30 Hydraulic tension lock studs then

these will need to be un-bolted / bolted accordingly, even if there is no actual Hydraulic tension systemfitted to your unit.

4. As you remove the bolts the clamp plates will now be loose. Carefully lift them out of their position whilestanding on the Product Conveyor. Place them safely on the Product Conveyor. Eye protection should beworn when working under the Screen.

8-26-1 Mesh removal – DISCHARGE END (continued)

5. Fixed to the side plates of the Screen Box are the Screen Sealing strips. To enable the discharge endScreen meshes to be removed there are 2 small Sealing Strips that require slackening. There is one strip

located either side of the Screen Box and held in place by 2 x M12 x 40 Bolts. Slacken off the holding boltsand pull the strip downwards. This will allow the mesh to be removed from the center beam easily. IfWalkways are not fitted then care must be taken when trying to access the Screen from the sides. It isrecommended that you work from a ladder that is suitably secured.

Taking the mesh out:

1. TOP DECK As you remove the bolts the clamp plates will now be loose. Raise the Screen mesh up andforward from the underside releasing it from the discharge end beam. You may need to knock the meshloose in the area of the discharge end beam using a heavy piece of wood. Carefully lift them out of theirposition while standing inside the Middle product Wing Conveyor feed boot (if bottom deck fitted) or bystanding on the Product Conveyor (if bottom deck not fitted). Place them safely on the Product Conveyor.Eye protection should be worn when working under the Screen.

2. BOTTOM DECK When the mesh is free, Raise the Screen mesh up and forward from the undersidereleasing it from the discharge end beam. You may need to knock the mesh loose in the area of thedischarge end beam using a heavy piece of wood. Carefully remove via the rear of the Screen Box, over therear access platform. Pass the mesh through the hand-railing and onto the Product Conveyor. Take care ofhands and fingers when handling meshes.

Use an overhead crane where possible and avoid manual lifting. Store the used mesh away from themachine.3. Remove any damaged Channel Rubbers.

Note: If replacing Top Deck meshes only, there is no need to separate the trestle as described in ThePreparation For Screen Change section . Allow the Screen / Product Conveyor assembly to be loweredcompletely ensuring the Screen Sub-Frame assembly is lowered onto the Chassis frame as described insection 8-21-1 items 1-7.

MAINTENANCE INFORMATION

1. Correct Maintenance Procedures ALWAYS:-

• perform maintenance on a level and solid surface. • ensure the undercarriage is solidly supported if work is necessary under the

track systems. • remove any build-up of grease, oil or debris. • repair all damage and replace worn or broken parts immediately. • use only specified lubricants, do not mix different brands or types. • check for oil leaks and damaged hydraulic hoses. • use great care when maintaining the hydraulic system since oil is very hot

when the machine has just been working. • dispose of lubricants in the proper manner.

Please note that the maintenance intervals specified are for normal working conditions. If the track system is used in severe working conditions then maintenance and safety checks must be performed more frequently.

2. Track Drive Unit 2.1 Routine Checks The first oil replacement for the gearbox is to be carried out after 100 operating hours. There after replace the oil every 1000 hours or at least once each year. It is good practise to check the oil level every 100 working hours or every month – whichever comes first. 2.2 Oil Filling To fill, track the machine until the gearbox casing is level with a plug positioned at 12 o’clock as shown below. Unscrew the two plugs and fill from the upper hole until oil flows from the lower hole. 2.3 Oil Draining To drain, track the machine until a pluUnscrew both plugs and allow all oil to

3. Track Group 3.1 Checking Track Tension Stop your machine on solid and level ground and drive 2 metres (minimum) in a forward direction. Measure the sag on the top part of the track on the longest section of unsupported track as shown below.

The sag of the track must be between 5mm and 15mm . If track tension is not within this range, follow adjustment procedure described in paragraph 3.2.

Carrier Roller or Skid Plate (whichever is fitted)


- Page 19 -



3.2 Track Tightening and Slackening

The grease contained in the track tensioner is pressurised so care must be taken when loosening the grease fitting (Item 2).

1. To tighten the track, loosen the two screws and swing access cover (Item 1) away from access aperture on the side of the track frame.

2. Connect a grease gun to the grease fitting and add grease until the track tension is within the specified values given in paragraph 3.1.

3. Drive 50 metres forwards and 50 metres backwards and repeat the above procedure if the track slackens.

4. To slacken the track, loosen the grease fitting (Item 2), by turning in an anti-clockwise direction, using gradual increments until the grease begins to be expelled. Care must be taken not to loosen the grease fitting too quickly.

5. When the correct track tension has been obtained, tighten the grease fitting by turning in a clockwise direction and clean away all trace of extruded grease.

If the track fails to slacken after grease fitting has been loosened, DO NOT attempt to remove the tracks or disassemble the track tensioner, or remove the grease fitting from the tensioner. It is possible that running the tracks with the grease fitting loosened may help to expel the grease.

WARNINGWARNINGWARNINGWARNING The following procedure involves working with grease contained at high pressure and must only be carried

out by qualified fitters.

ITEM 2 ITEM 1

3.3 Removing the Track To uncouple the track group the following procedure must be followed:

1. Jack up the machine and block safely on firm, level ground. 2. Release the tension on the tracks (as described in paragraph 3.2). 3. Locate the master pin. This can be identified by the indentations in each of

the end faces. 4. Rotate the track until the pin is in approximate position (as shown above)

and place a block under the front of track. This prevents the chain from dropping once the master pin has been removed.

5. The master pin can now be pushed out from the chain, separating the track.

WARNINGWARNINGWARNINGWARNING When removing the master pin, do not use a sledge hammer. This may cause splintering of the metal

with the possibility of injury.

6. The track can now be pulled from under the machine.

WARNINGWARNINGWARNINGWARNING Care must be taken when pulling the track chain from under the machine to avoid dislodging the blocks or

stands supporting the machine.


- Page 21 -



3.4 Rejoining the Track To rejoin the track group, the following procedure must be followed:

1. With the track chain lined up (i.e. with pin holes and the bushing aligned), a

dummy pin should be inserted with the collars in position.

2. The track press should then be set up, with the master pin in position.

3. Press the master pin into the chain, pushing the dummy pin through the link.

WARNINGWARNINGWARNINGWARNING A sledge hammer should not be used to insert the

master pin. This may cause splintering of the metal with the possibility of injury.

4. Component Wear 4.1 Track Shoe Wear

The most important wear of a track shoe is the relative height of the grouser to the top of the shoe plate. A depth gauge should be used to measure this.

4.3 Internal Pin and Bush Wear

Measurement is made of the elongation of the chain pitch. A standard steel tape can be used. To determine the average internal pin and bushing wear measure across a piece of chain comprising of 4 links (5 pins). This track section must not include the master pin, and should be on the upper side of the track and well stretched.

4.4 External Pin and Bush Wear

Wear of the bushes is caused at the point of contact between the bushing and the sprocket tooth. To measure this wear use a small outside calliper. Outside wear of the bushings can be of any of the 3 types shown above. Measurements should be taken in each position and the area where wear is maximum should be considered.

4.5 Bottom Roller Wear

The tread wear of the roller is the most important wear area and is measured on the roller diameter. The most suitable tool is a large outside calliper. The correct measurement is to take the smallest diameter of either tread on the roller with the highest wear. Due to the difficulty in carrying out this measurement whilst the rollers are fitted to a machine, it is usually sufficient to measure the rollers closest to the idler and the sprocket, as the greatest wear occurs at these two points.

4.7 Sprocket Wear

Sprocket wear is very difficult to assess accurately. In fact, under normal working conditions, the wear occurs in such a way that no trace of the original toothing remains as a valid reference for measuring the wear. It is therefore impossible to provide 100% accurate data for wear measurement. As an approximate rule, the sprocket should be replaced when wear has reached the limits shown in the above illustration. As the wear is never uniform, it is necessary to consider the point at which the wear is at a maximum.
