9 MAINTENANCE, LUBRICATION, OIL CHANGE
9.1 SAFETY INSTRUCTIONS - Only trained, qualified and approved personnel may carry out maintenance or repair on this
equipment. These persons must have the mechanical and hydraulic skills required for assessing whether or not the equipment can be used safely. Marrel organises training sessions for maintenance of its products. If you require these, ring our technical department.
- You must NEVER take action on the hydraulic circuit. There are several hazards on this circuit: hot pressurised oil, unanticipated movement of moving parts (skip, connecting rod, etc.), uncontrolled operation of the equipment, etc. Never attempt to repair your equipment alone. If necessary, call in an approved specialist. Our technical services are at your disposal for all maintenance operations.
- You must not attempt to resolve electrical problems unless you have approval. There is a risk of damaging the vehicle’s electrical circuit.
- You must NEVER attempt to adjust or repair safety contactors. For your safety and that of other persons at risk, these contactors must never be de-activated. NEVER attempt to operate safety contactors manually. There is a risk of crushing.
- Pressure limiter settings are adjusted and lead-sealed for your safety. It is FORBIDDEN to modify these settings in any way. Modifications may result in: - equipment malfunction, - mechanical overloads that cannot be borne by the equipment.
- You must never get INSIDE skips or on the equipment, or attempt to reach them by supporting yourself on machine parts not designed to take your weight.
- As far as possible, maintenance operations must be carried out from the ground. If this is not possible, take the greatest care: use an appropriate means of access and check that it is stable and sound. Implement all the necessary safety measures for the work concerned (safety harness, non-slip shoes, etc.).
- All servicing and maintenance operations must be carried out with the machine off and the hydraulic circuit COLD. Disengage the power take-off, switch off the vehicle engine and keep the contact key on you. Take all necessary measures to ensure that the controls cannot be actuated during your maintenance work. You must never take any action on operating equipment even if the job seems straightforward and safe (lubrication, etc.).
- Check that the work environment lighting provides sufficient visibility for safe operation. - Do not use a blow torch on your equipment. There is a risk of fire and cylinder explosion. - Do not attempt to locate a leak by moving your hand over the equipment. Hot pressurised oil
is dangerous. - At the end of maintenance operations, check that you have left nothing in the vehicle or
equipment.
Never work on the arm’s cylinders and on the arms unless they are properly blocked
42
9.2 ROUTINE SERVICING AND MAINTENANCE 9.2.1 EQUIPMENT CONDITION
At least once a month check: The tightness of bolts and flanges securing the fixed subframe to the vehicle chassis.
Apply the following torques:
VIS ∅ x PAS CLASSE COUPLE EN m.daN M10x1.5 8.8 4.6 ±1
M12x1.25 10.9 12 0/-0.3 M14x1.5 10.9 18 0/-0.5 M14x2 8.8 12 0/-0.3 M16x2 8.8 18 0/-0.5
Frequency: Every week for 2 months then once a month Absence of leaks at hose couplings and the various hydraulic parts.
Do not overtighten couplings as this may damage and eventually break the nozzles.
Do not retighten leaking nuts, seals and couplings while the circuit is under pressure..
43
Le Oil level and cleanness with vehicle parked on the level and cylinders retracted.
Hose condition:
Inspect the hoses carefully to detect any deterioration or defect likely to create a danger. Hoses are prone to ageing which depends on the operating and storage conditions of the equipment:
- temperature, - work atmosphere, - number of daily operating cycles, - maintenance level, - pressure level required for loads involved, - etc.
Given all these parameters, it is very difficult to assess a “normal” service life for a hose. By default, MARREL recommends replacing hydraulic hoses every 5 years on the understanding that this interval can be assessed and modified by the person in charge of inspecting the equipment.
Check:
Absence of play in the joints Condition of plate metal components (arm, stabilizers, frame, etc.) and hydraulic components (cylinders) Operation of safety devices: Operation of immediate shutdown systems. circlips at all articulation of arm ,telescope and jack cylinders wearing pads in stabilizers and optional telescope safety system on tipping hooks
.
OIL LEVEL
44
9.2.2 LUBRICATE under :the zerk fitting at the same time as for the truck and after any washing (see lubrication points on sketch) Grease properties : see «INGREDIENTS»page clean :
- The cylinder rods of the arms with a clean rag ,while checking for any dent -
9.2.3 CLEANING :
CAUTION: Do not clean the SKIP LOADER with a steam jet cleaner during the first 6 weeks. When cleaning your equipment, avoid damaging the paint by ensuring that the nozzle is at least 30 cm from the surface to be cleaned.
IMPORTANT: Follow these instructions strictly. Failure to do so will affect your rights under the warranty.
45
CAUTION: Do not attempt to carry out this oil change ALONE. Seek assistance from an APPROVED person. This operation requires delicate work on the hydraulic circuit and there are many potential hazards (unanticipated movement of moving parts, hot pressurised oil) requiring specific safety devices to be set up (arms supported by a hoist etc.).
9.3 OIL CHANGE The oil change is a complex operation on this equipment and requires special handling equipment and tools. In addition to draining the tank, it requires action on the complete hydraulic circuit. Have this operation carried out by an approved centre. If necessary contact our technical department.
The oil change must be carried out every 2000 operations or once a year at the beginning of winter to reduce the effects of condensation. Change the oil filter cartridges and the breather cartridge after the first two months of operation, then once a year. .

11 PANNES - CAUSES - REMEDES
11.1 TROUBLESHOOTING - comply with the safety instructions in ch. 10.1 - do not replace original parts with parts not supplied by the constructor. this affects
safety and the warranty. - do not carry out welding operations on the vehicle without taking the necessary
precautions (see vehicle constructor’s manual). if you fail to comply with the constructor’s recommendations you may damage on-board electronic equipment.
- never replace a durite hose with an ordinary rubber hose lacking the necessary thermal and mechanical characteristics: the hydraulic circuit operates under 350 bar.
- the machine must be powered down (power take-off disengaged, vehicle engine switched off, ignition key on your person) and the hydraulic circuit allowed to cool before any maintenance work.
- hot pressurised oil is dangerous. - if a hose bursts, release the power take-off and stop operating. do not attempt to lower
the equipment. contact a qualified person immediately. if necessary call our technical department). As far as possible, protect the ground from oil leaks..
- If the equipment breaks down at the work site or on the highway:
Park in a place where you and others will be safe and where you can be clearly seen.
Switch off the engine, put on the parking brake and shim the vehicle wheels. If you are carrying out a skip operation and the SKIP LOADER cannot be put in
its rest position, mark out the hazardous area. Notify the site foreman immediately. If the vehicle has to be towed, contact a qualified person from your company or
an approved recovery service.
- Repair operations may only be carried out on the equipment by specifically trained, qualified and approved personnel. You must never attempt to remove any hydraulic, electrical or mechanical parts as there is a risk of unanticipated movement of moving parts, uncontrolled operation of the equipment, safety device malfunction, crushing, etc. Switch off your vehicle engine, disengage the power take-off, mark out the area and call in a specialist.
- You must never actuate or de-activate safety contactors manually to repair the equipment.
Your safety depends on them.

upward and keep the control operated a few minutes
- Check the strainer or filter and the suction hose - Check the type of oil (grade,viscosity index )and
absense of water Jerky operation Load retaining
valve - - Check inside parts of valve (seals,base,spring)
No movement at all ,even without any load
Air controls - Check the air supply - Look for a broken air control line - Check and change the corresponding switch
P.T.O - If pump does not rotate check the P.T.O. control Oil
- If pump is running ,check the oil level
Pump - internal fracture of pump container :repair or change .
- we would advice you to contact your nearest service dealer for this maintenance .After every disassembly of the pump it is imperative to strictly follow instructions and re assemble correctly so as to ensure proper operation of the equipment .
- clean all the components in the system The arms do not lift a loaded container from the ground
Heavy load - over load :remove some load from the front and check the weight on a scale
Relief valve - Check the setting of the main relief valve :350bar = 5,000 PSI max.(read the gauge when the arms come to upper or lower stop position.
Front axle lifts off the ground
- the jacks have not been lowered or are not on the ground
- check the weight Oil pollution - After severe usage oil in the system may be
polluted, spools damaged and are not working to their full extent, cylinder could also be scratched and piston seals may be worn.
- Repair, clean out the system and refill with oil Backward movement stops before end of stroke
Oil level - check and top up The arms meet an obstacle
- eliminate the obstacle
Slow movement of the arms, after pump is stopped
Air pocket in the oil circuit
- Bleed the cylinders by opening and closing the cylinders to full stroke several times
- Look for air intake :tighten clamps on suction hose and pump
- Check anti foam properties of the oil
49
Delayed control Air lines partly obstructed
- Look for the sharp bend on air lines to the control valve.
- Change the line and find a better route The arms do not lift the load from the platform to the ground
The bucket has been over load (while on the truck )
- Remove some of the load out of the bucket
The tipping hooks do not work properly
Lack of air supply - Check the air pressure supply(7bar=100PSI)
Air leaks - seal Obstructed filter in air exhaust
- Pierce the filter or change it
Air solenoid valve failure (under platform at rear )
- Change it
The skip doesn’t come to rest on the platform after tipping the hooks being engaged
The skip doesn’t comply with the standard dimensions or the chains need adjustment
- Go back to tipping position until the hooks are free and then get them off
- Check that the skip complies with standards and that the chains are correctly adjusted
Noise :vibrating Pump - Check the oil level - Some in or out valves may be leaking ;contact
your nearest approved repairs workshop Drive line - Check drive shaff seals and tighten .check for
looseness in the crosshead Shrilling or squalling
Load retaining valve
- Adjust the check valve or change its spool
External oil leaks
Pump shaft - Change the shaft seal Cylinder rod - Change the seals .Look for scratched rod
(changed the seals does not help if the rod is damaged )
Fittings - Tighten the appropriate coupling (do not overtighten or renew sleeves)
tank - Overflooding :the oil level was too high after a refill ,all cylinders retracted
- Check the anti-foam properties of the oil No dumping even with extended jib
Tipping hooks - Hoks don’t catch the tipping bars free the hooks,clean and lubricate .Add or modify the uncorrect tipping bars.
overload - Check the payload or its distribution in the body
Unbalanced load - The hooks are not engaged correct the balance of the load
Severe side slope - The hooks are not engaged .repeat the operation on stable ground

12 NOISE READING Noise measurements are carried out on a representative sample of the equipment. TEST CONDITIONS:
- Machine operating in the open air - Operating conditions representative of actual conditions of use (over 1 cycle) - Measurements taken at the work station (in the cab) - BRUEL-KJAER sound level meter, type 2231, class 1 in SLOW mode - Measurement of equivalent acoustic pressure levels - Average ambient noise roughly 50 dBA
The measurements establish that the global airborne noise is due mainly (for more than 90%) to the carrier vehicle engine. You will find the airborne noise level emitted by your vehicle in the constructor’s manual. Operating the SKIP LOADER increases the carrier vehicle sound level by less than 5 dB. At the work station (carrier vehicle cab), the equivalent acoustic pressure level may slightly exceed 70 dB.
51
13 ROUTINE GENERAL INSPECTIONS
- The SKIP LOADER must be inspected every 6 months to detect any malfunction capable of causing an accident.
- The checks must be carried out by qualified personnel, specifically assigned by the site director and under his responsibility (company or non-company personnel). These persons must have the mechanical and hydraulic skills required for assessing whether or not the equipment can be used safely. This assessment is difficult to qualify and quantify and requires a good level of experience in the matter. For further help, ring our technical department.

14 PRIOR TO USING YOUR EQUIPMENT
- You are now familiar with your machine and you know your operating site. - Follow the operating instructions which have been given to you by both the vehicle and
skip loader manufacters - Using “the operator‘s manual “provided with your skip loader you must check your
equipment. - Have a good lock round the whole vehicle ,checking : - That there is no oil leakage in any hydraulic component ,couplings and pipes - The fixings of the equipment to the chassis and pivoting points - The level of the hydraulic oil: this check must be made with cylinders in the closed
position - The condition of the swivels (plates at the end of the chains) and the lifting pins (lugs
on, the container) - The condition of the tipping hooks - The conditions of the mechanical components of the machine - Notify your site manager or service manager immediately if you discover any faults ,no
matter how small NEVER OPERATE A DEFECTIVE MACHINE.
57
15 MAINTENANCE AND REPAIR
• Your Skip loader must be maintained regularly, and if you discouer any fault this should be repaired immediately.
• We would remind you - - That maintenance/repairs must always be undertaken by specially trained, qualified
personnel. - That you must never attempt maintenance / repairs on a machine which is operating,
even though the repair may appear to be simple and without danger (greasing ...). - Immobilise the moving parts and the vehicle by placing a strong wooden or metal block
or suitable prop under the frame, the dimensions of which must be adequate to prevent damage by crushing - NEVER IMPROVISE, THIS ISAN IMPORTANT SAFETY MATTER.
- That you must not operate the safety interlocks by hand when operating the machine (such as the pressure limitation for the extension of cylinders).
- That these interlocks must not be tampered with in any way - your safety is jeopardised by any interference.
- Grease regularly at the points shown in your «operator's manual», especially after pressure washing the equipment.
- Never weld on the vehicle without having previously unplugged the battery and follow the manufacturer's instructions: take care with all electronic equipment mounted to the vehicle.
- - At the end of your maintenance check that you have removed all tools and equipment from the vehicle (platform frame, ...)
58
16 BEFORE ROAD USE - Before getting in the cab go round and check that no-one is nearby or under the vehicle
(greasing, resting...), if so, move them away. Check that there are no tools under your vehicle or the equipment (platform frame)....).
- If tools remain in the front tool box ENSURE THEYARE CORRECTLY secured. - To get into the cab follow the existing company safety regulations, using handrails and
steps provided. Never step on parts of the equipment which are no designed to be used as steps (cylinders, pipes....)
- Remember visibility: you should have a clear view all round from the cab (by using the
side mirrors, screen ). Pay attention to the extending arms (where applicable). - You should be aware of the dimensions of the vehicle and equipment in all modes of
operation: on-road driving, loading on and off, tipping ... (contact our technical department if necessary).
- Respect highway regulations and the payload limitations shown in your log book.
- That you must lift on or off, or tip the container on level, hard and stable ground.
- That you must take all measures to ensure that controls and switches cannot be
operated during maintenance (the key must not be in the ignition -put it in your pocket! - display a warning sign for others, ...)
- - Take care if several workers operate the same machine: there must be coordination of
operations. - If you are working in a covered area ensure that there is sufficient height to operate the
machine - Never try to stop a leakage with your hands, oil under pressure is dangerous -
59
- Before maintaining the hydraulic System be sure that the engine is not running and PTO is disengaged
- Always de-pressurise the hydraulic System in both extend and retract modes, - Do not tighten the bolts, gaskets and couplings when the hydraulic System is under
pressure - Cool the hydraulic System down before attempting maintenance even for a simple oil
change, - To fill bleed or change the oil System, slowly loosen the filler and oil level caps,
and drain plug - In order to maintain a clean hydraulic System, filters should be used when introducing
new oil. - When maintenance is finished do not forget to carefully re-tighten ail the caps. - So as to control the settings of the hydraulic System use the appropriate pressure
gauges in good working condition: plug them in the correct places as shown in your manual.
- Never change the settings on the pressure relief valve: if they are changed you risk
serious damage to your machine and may cause an accident. - Always use the correct torque settings shown in the parts manual.
60
17 BEFORE LOADING AND UNLOADING
- Ensure that there is sufficient space in front, to the rear and sides of the vehicle to enable operation of the equipment. If necessary leave the vehicle and check all round to be absolutely certain. If any person is standing in the immediate area they should be asked to move.
- If you are working at night or dark conditions, light the area. - Ensure that no obstacle hinders your vision or your ability to manoeuvre. If you
cannot manage on your own then you should request assistance to negotiate the obstacle.
- You are advised to use containers made to recognised standards and which are compatible with your equipment especially within length and width dimensions (position of centre of gravity of the vehicle), check the locking and hook mechanisms. If the container and skip loader are not compatible in all respects, you risk the danger of problems with the rear of the vehicle, arm, spacer, guides for the container, front face and thrust of the container, rear side of the cab, etc.
- Ensure you position the bin stops for the container in the appropriate slots
61
- Check for the correct length of the chains (see your «operator's manual» provided with your equipment).
- If you are working in a built up area be aware of pedestrians and other traffic. - Display warning signs in the working area, - No-one must climb on the skip loader while it is in operation - if someone is on the skip
loader do not starts work. - Check ground conditions. - When using stabiliser jacks, check ground résistance paying particular
attention to manhole covers, soft ground etc. The stability of the vehicle depends totally on the ground conditions: soft or uneven ground will not provide stability.
- Always use both stabiliser jacks for correct stability. - Check alignment of container and arms. If you cannot manage, do the
operation again. - Do not try to drag or push a container which is on the ground. - Do not load on unstable ground. - Pay special attention when loading onto a trailer: follow the instructions given in
the «operator's manual» provided with the equipment. - Using the appropriate means secure the load safely. - Loading must be carried out so that nothing wills fait from the load when the
vehicle is travelling: clean the platform frame if necessary. - With the tipping container on the ground, ensure the load is evenly
distributed
62
- If the load is to be covered, secure the cover over the load whilst it is at ground level, unless a mechanical sheeting device is fitted.
- When loading with an auxiliary crane: - Follow the instructions and regulations concerning use of the crane, - Do not exceed the maximum loading weight of the crane, - Take care when manoeuvring loads.
• Never stand under or at the rear of a partially tipped load or while the vehicle is being manoeuvred.
• If you are using other methods of loading than from the ground or a trailer (a crane, hopper, ...) YOU MUST WEIGHT THE LADEN VEHICLE BEFORE DRIVING OF If there is an overload, reduce to the maximum authorised payload, otherwise you risk instability of vehicle and equipment while unloading.
63
18 STANDARD HAND SIGNALS
64
19 LOADING
- Follow the instructions in the correct order shown in manual. - Do not allow anyone to approach the working area, and pay special attention when
placing the stabiliser jacks (option) - you may injure someone's foot. - Where cab mounted controls are fitted, do not leave the cab whilst loading the
container from ground level or from a hole or a trailer (in case of problems with the control switches you can stop the operation by use of the clutch pedal) Where side of chassis manual controls are fitted, release the spring centred levers to stop operation.
- Do not exceed the maximum permitted load weight, detailed in the vehicle log book and vehicle identification plate.
- Do not exceed the Pto/pump speeds. - Do not modify the position of the extending arms (where applicable) whilst operating. - You must not change the position of stabiliser jacks when in use.
65
20 UNLOADING • TO GROUND LEVEL, TO A HOLE OR ONTO TRAILER.
- Where cab mounted controls are fitted, do not leave the cab while unloading the container to ground level, a hole or a trailer: in case of problems with the control switches, you can stop the operations by use of the clutch pedal. Where sides of châssis anual controls are fitted, release the spring centred levers to stop operation.
- Do not forget to lower the tipping hooks. - You must not try to modify the position of extending arms (where applicable) whilst
operating. - You must not change the position of stabiliser jacks when in use. - Do not operate if the side slope may cause an over-turn.
- At the end of the operation, if your equipment is fitted with a crossbeam, release the control: failure to do so would mean that the crossbeam will hit the container, and cause serious problems with the cylinders.
- - When uncovering the load, take the cover off with the container on the ground, unless a mechanical sheeting device is fitted.
• TIPPING OPERATIONS - Where cab mounted controls are fitted, do not
leave the cab while tipping: in case of problems with the control switches you can stop the operation by use of the clutch pedal. Where sides of châssis manual controls are fitted, release the spring centred levers to stop operation.
- Do not forget to set the tipping hooks to tipping position.
- When tipping, we would advise you to use the
stabiliser jacks. It is imperative to use the stabiliser jacks on a stable ground when tipping in deep holes.
.
66
21 WHEN DRIVING • Before starting, ensure that -
- Doors and sides are properly closed; loads are evenly distributed and well secured. Do not attempt to level the load whilst the container is on the vehicle,
- The Centre of Gravity is as shown on the vehicle plates where appropriate. (See operator's manual),
- the container is properly secured on the platform frame : correct location of bin stops for the container,
- the chains are well secured to the lifting pins and are not taught or excessively loose (beware of the risk of swinging chains),
- the dimensions of the materials to be carried must not exceed the container or equipment dimensions,
- if you are driving unladen,the arm must always be in the forward position (behind the cab), the chains must be secured in their appropriate safety position,
- Doors and sides are proper/y closed. - do not forget to retract stabiliser legs before moving off, - do not forget to retract the extending arms (where applicable).
• Do not drive with PTO engaged. • When the vehicle is laden do not drive on unstable ground with longitudinal or transverse slope. • Do not drive too close to pedestrians. • Do not carry personnel in the body or on the equipment even for short distances. • When unladen do not drive with the arms to the rear.
67
- If you are tipping sand or gravel don't forget to open the rear door, if appropriate. - Take care with the differing designs of tail doors: remember that the load is exerting a
force onto THE TAILDOORS THAT COULD LEAD TO THEM SUDDENLY OPENING. Take care that no-one is standing within the danger area of the doors (especially you!) and there is no other object in this area. Take account of the added dimension of the locking device. Make sure any mechanical sheeting device is retracted.
- Whilst tipping, if you have not stabilised the vehicle with jacks : never shake the container, by shocking the rear wheels onto any rocks or nearby object, or by use of the controls, or shunting the vehicle
- Never stand under or at the rear of a partially tipped load or while the vehicle is being manoeuvred.
- Ensure that no obstacle hinders your vision or your ability to manoeuvre. If you cannot manage on your own then you should request assistance to negotiate the obstacle.
- Keep away from electric cables; contact the electricity authority to determine the voltage of cables where you are working.
68
22 BREAKDOWNS
• In case of breakdown in a public or working area : - Park in a safe area for you and others where you can see and be seen, display
appropriate warning signs (fluorescent triangle, hazard warning lights etc. ...). - Switch off engine, lock the parking brake and secure the wheels with blocks. - If breakdown occurs during an operation and the vehicle cannot be made safe, warning
signs advising of the danger should be displayed. - Immediately advise your superior of the situation. - In order to undertake any repairs, the operator must have had the necessary - training and be suitably qualified
- If repairs have to be undertaken on site, the repairer must follow site safety regulations, as well as the vehicle and equipment manufacturer’s safety regulations
- If you have to tow the vehicle, call a specialist from your company or call a patented maintenance repairer.
