OPERATING INSTRUCTIONS

The unit must be properly operated and properlymaintained to help avoid accidents that coulddamage the unit and injure the operator orbystanders. This section of the OperatingInstructions manual review basic operations and useof controls. These instructions should be reviewedwith all employees before they are allowed to workwith the machine. Keep these instructions near themachine for easy reference.

BEAD LOOSENING AND DEMOUNTING

This machine mayoperate differentlyfrom machines you

have previously operated. Practice with a regularsteel wheel and tire combination to familiarizeyourself with the machine's operation andfunction.

Remember to remove all weights from both sides ofthe wheel. Weights left on back side of wheel maycause the wheel to be clamped unlevel. This mayresult in the combination mount/demount headcontacting the rim causing scratches. On alloywheels, always rotate the wheel one turn aftersetting the head to insure proper wheel chucking.

NOTE: Always review nicks and scratches withowners of expensive wheel and tire combinationsprior to servicing.

IMPORTANT: Review the performance wheelsection of this manual prior to servicing performancetire/wheel combinations.

1. Deflate tire completely by removing the valvecore from the valve stem (Figure 1).

Figure 1 - Remove Valve Core to Deflate Tire

NOTE: Loosening the beads on a partially orfully inflated tire is unsafe and causes excessmovement and friction against the bumper padsand excessive wear on pivots. Deflate the tirecompletely to prolong the life of your machine.

NOTE: Always loosen the bead on the narrowside of the wheel's drop center first. See Figure4 for more information on the drop center.

REMEMBER: The clamps on the table top mayextend beyond the table top itself. To avoiddamaging the clamps, move them to their fullinward position before positioning a tire for beadloosening.

NOTE: Use extra care in positioning the beadloosener shoe on larger wheels/tires, and onalloy wheels. Make sure the shoe rests next tobut not on the rim, and not on the tire sidewall.

2. Pull the bead loosener shoe away from themachine and roll wheel into position. The valvestem should be in the 3 o'clock position. Positionthe bead loosener shoe against the tire next to,but not on, the rim. Depress the bead loosenerfoot pedal to actuate the shoe and loosen thebead. It may be necessary to loosen the bead inmultiple locations around the tire (Figure 2).

Figure 2 - Position Tire and Bead Loosener Shoe

3. Turn wheel around and repeat looseningprocedure on the other side of the wheel. Thisshould be the long side of the drop center (seeFigure 4).

TIP: It will be easier to clamp the wheel to thetable top if the lower bead is loosened last.

4. Apply tire manufacturer's approved rubberlubricant liberally to entire circumference of bothtire beads after loosening.

Figure 3 - Apply Rubber Lubricant to Tire Beads

5035 A/E Rim Clamp Tire Changer • 3

CAUTION!

5. Determine the mounting side of the wheel. Themounting side is the narrow side of the dropcenter. (Tire removed in Figure 4 for clarity.)

Figure 4 - Determining Mounting Side of Wheel

6. Place tire/wheel assembly on table top withmounting side up (Figure 5). Use the clampcontrol pedal to move the clamps inward (pushpedal down) or outward (toggle pedal up).Clamp steel wheels from the inside (clampspush outward against wheel). Clamp mag andcustom wheels from the outside (clamps pushinward against the outside rim edge). Refer tothe Performance Tires and Wheels section.

Figure 5 - Place Tire/Wheel Assembly on Table Top

7. Move the swing arm into position. Pull thelocking handle forward to release the slide.Push down on the top of the vertical slide tomove the demount head into contact with therim edge. Push the locking handle back to lockthe slide into place. As the slide is locked, themount/demount head wil l move upwardapproximately 1/8 inch from the rim edge.

Figure 6 - Position Mount/Demount Tool

8. The mount/demount head roller should be incontact with the rim edge. Turn the swing armadjusting knob to move the roller away from therim 1/8 to 1/4 inch.

Figure 7 - Adjust Swing Arm to Position Head Roller

9. Check head positioning. Mount/demount headshould be positioned with 1/8 to 3/16" clearancebetween the top of the rim edge and the bottomof the head, and 1/8 to 1/4 inch clearancebetween the rim edge and the head roller. Thisclearance will be maintained as long as thelocking handle and adjustment knob are notchanged. The operator may swing the arm outof the way and back into place again withoutneeding to reposition the head (when changingthe set of same wheels).

Figure 8 - Proper Mount/Demount Head Position

IMPORTANT: The vertical tool clearance maychange with machine use and should beinspected often. Failure to maintain the properclearance may result in damage to the wheelrim and/or tire.

10. Insert the smooth curved end of the bead liftingtool over the forward end of the demount headand below the top bead of the tire. Use your freehand to press down on the tire opposite thehead to help with tool insertion (Figure 9).

12. Depress the table top pedal to rotate the wheelclockwise. The demount tool will guide theupper bead up and over the edge of the wheel.

NOTE: Push down on the tire across from thedemount head during table top rotation to utilizethe drop center area of the wheel. This reducesthe tensional force on the bead during demount.

13. Lift and hold the tire at an angle so that thelower bead is resting in the drop center directlyacross from the demount head, and is loosebelow the demount head (Figure 11). Insert thesmooth curved end of the bead lifting tool downover the forward end of the mount/demount tooland below the lower bead. Lift the bead up andover the knob on the demount head (Figure 11).

Figure 11 - Demounting Lower Bead

14. Depress the table top pedal to rotate the wheel.The demount tool will guide the bead up andover the edge of the wheel. Continue rotationuntil lower bead is demounted.

NOTE: With tube-type tires, demount the upperbead and remove the tube before demounting thelower bead.

NOTE: Table top rotation can be stopped at anytime by removing your foot from the pedal.

NOTE: Normal table top rotation for demounting isclockwise. Depress the table top pedal to rotate thisdirection. To rotate the table top counterclockwise,lift the pedal up with your toe.

At times during themounting anddemounting proce-

dure, the bead lifting tool may encounter resis-tance or come under load. Keep one hand firmlyon the tool to avoid possible tool disconnect.Use the reversing feature to back out or jam ups.

After successfully completing the demountprocess, proceed to Mounting (page 6).

Operator Protective EquipmentAlways wear durable work clothing during tireservice activity. Shop aprons or shop coats mayalso be worn, however, loose fitting clothing shouldbe avoided. Tight f i t t ing leather gloves arerecommended to protect the operator's handswhen handling worn tires and wheels. Sturdyleather work shoes with steel toes and oil resistantsoles should be used by tire service personnel tohelp prevent injury in typical shop activities. Eyeprotection is essential during tire service activity.Safety glasses with side shields, goggles, or faceshields are acceptable. Back belts provide supportduring lifting activities and are also helpful inproviding operator protection.

CAUTION!

MOUNTING

This information must be read and followed carefullyto prevent accidents and injuries during mounting.

Check tire and wheelcareful ly beforemounting. Make sure

the tire bead diameter and wheel diameter matchexactly. Consult the Rubber Manufacturer'sAssociation for approved rim widths for tiresizes. Mis-matched tires and wheels explode.

Never Mount a tireand wheel handed toyou by anyone with-

out checking both tire and wheel for damage andcompatibility. Be extra cautious of persons with-out knowledge of tire service. Keep by-standersout of service area.

Never mount a damagedtire. Never mount a tireon a rusty or damaged

wheel. Damaged tires and/or wheels may explode.

If you damage thetire bead duringmounting, STOP!,

remove the tire and mark it as damaged. Do notmount a damaged tire.

1. Inspect the wheel closely for damage. Clean thewheel and remove any light corrosion or rubberresidue (Figure 12). Do not attempt to serviceheavily corroded wheels.

Figure 12 - Inspect and Clean the Wheel

2. Inspect tire for damage, paying close attentionto the beads. Verify size match between tire andwheel (Figure 12).

3. Lubricate tire beads liberally with tire manufac-turer approved lubricant (Figure 13).

Figure 13 - Lubricate Beads

4. Place tire over wheel and move swing arm intoposition. Position the tire so that the lower beadis above the rear extension of themount/demount head and below the front knob(Figure 14).

Figure 14 - Position Tire Against Mount/Demount Head

5. Depress table top pedal and rotate the wheel tomount the lower bead. Use the drop center ofthe wheel to reduce the tensional force on thebead by pressing down on the tire directlyacross from the mount head.Rotate table topuntil lower bead is fully mounted.

6. For top bead, rotate the table top until the valvestem is directly across from the mount head. Liftthe upper bead up and over the rear of themount head. With your left hand press down onthe tire between the mount head and the valvestem to hold the tire in the drop center. Depressthe table top pedal and rotate the tire until thebead is mounted. Continue to press down onthe tire during the remaining mounting process.

Do not force the tireonto the rim. Beaddamage could result

making the tire unsafe and/or creating the risk ofinjury.

NOTE: If table top rotation stalls, reverse the tabletop momentarily until the tire bead is again loose onthe wheel. Reposition the mount head, make surethe bead is correctly positioned in the drop center ofthe wheel, then attempt mounting again.

NOTE: For low profile or stiff sidewall tires, it may beadvantageous to use the bead lifting tool to initiallyhold the upper bead down in the drop center, or usedrop center tools as shown in Figure 30, page 11.

NOTE: For tube type tires, mount the lower beadfirst, move swing arm out, install the tube, and thenmount the upper bead.

When you have completed the mountingprocess, proceed to Inflation, page 7.

INFLATION

Tire inflation is performed in three steps: Bead Seal,Bead Seat, and Inflation. These steps are explainedin detail on page 13. Read the explanation of eachstep and understand them thoroughly beforeproceeding.

Check for proper infla-tion gauge operation.Accurate pressure

readings are important to safe tire inflation.Refer to the Operating Maintenance section ofthis manual for instructions.

If the rim has beenclamped from the out-side for tire mounting,

release the clamps, lift the tire, and move theclamps to the center of the table top.

If the wheel/tire has adiameter larger than14 inches and is diffi-

cult to bead seal, the clamps should be movedto the center of the table top for the bead sealoperation.

Tire failure under pres-sure is hazardous. Thistire changer is not

intended to be a safety device to contain explod-ing tires, tubes, wheels, or bead sealing equip-ment. Inspect tire and wheel carefully for match,wear, or defects before mounting. Always useapproved tire bead lubricant during mountingand inflation.

The inflation pedal, located at the rear of the left sideof the machine, controls the flow of air through theinflation hose.

NOTE: The clip-on chuck on the end of the hoseshould always be an open style with all parts inproper working order.

Position 1 - At Rest – With the inflation hoseattached to the tire valve and the pedal in thisposition, the air gauge will register the air pressurein the tire. Whenever your foot is removed from thepedal, it will return to this position.

Position 2 - Tire Inflation – This is the firstactivated position. With the inflation hose attachedto the tire valve and the pedal in this position, linepressure is allowed to flow through the valve andinto the tire for inflation. Tire pressure is notindicated on the gauge in this position.

Position 3 - Bead Sealing – This is the second andlast activated position. With the inflation hoseattached to the tire valve and the pedal in thisposition, line pressure is allowed to flow through thevalve and to the air-flate bead seal jets on the tabletop for bead sealing.

Use Position 3 forbead sealing only. Donot use this position

without a tire and wheel positioned on the tabletop. Dirt and debris could be blown into the air withenough force to injure the operator or bystanders.Do not use the position to inflate a tire.

IMPORTANT: The unit is equipped with a pressurelimiter to assist the operator with proper tire inflation.When the inflation pedal is held in position 2, thepressure l imiter cycles the machine betweenposition 2 (inflation) and position 1 (at rest, no airflow to tire). This cycling helps to prevent overinflation of the tire. Tires can still be over inflatedand explode with the use of this pressure limiter if allof the instructions in this manual are not followedcompletely. The pressure limiter will keep most carand light truck tires from inflating beyond 60 PSI(smaller tires may reach higher pressures). It is theoperator's responsibility to follow all instructions andto control inflation pressure as specified in theseinstructions. Check the function of the pressurelimiter regularly and maintain it according to theinstructions provided in this manual for safe andproper operation. Tires that require inflation beyond60 PSI should be inflated in a safety cage.

Bead Sealing

1. Connect the inflation hose to the tire valve stem.Hold the tire up against the upper edge of thewheel. Be sure the top bead of the tire is overthe bottom of the valve stem (Figure 15).

2. Depress the inflation pedal to position 2 andhold about 1 second to begin air flow, thendepress pedal to position 3 and hold very briefly– less than 1 full second. The blast of air fromthe jets will expand the tire and seal the beads.

3. Remove your foot from the inflation pedal andallow it to return to position 1. Verify that bothbeads are completely sealed to the wheel.Repeat these steps if beads have not sealed.

NOTE: If tire and wheel are properly lubricated andthe operator cannot achieve bead seal after 3 or 4attempts, the valve core may be removed from thevalve stem to allow more air into the tire to assistwith bead seal. After bead seal is achieved, removethe chuck and reinstall the valve core.

Bead Seating

Operator should keephands, arms, andentire body away

from the tire during the remaining bead seat andinflation procedures. Do not stand over tire, aspersonal injury could result.

NEVER increase airpressure to exceed 40PSI when attempting

Bead Seat. If operator is unable to obtain BeadSeat, something is wrong. Deflate tirecompletely, inspect both the tire and wheel,correct any problems found, relubricate both tirebeads, and reattempt Bead Seal and Bead Seatprocedures. Follow all safety instructions in thismanual and on machine.

1. Once tire pressure is indicated on the air gauge(inflation pedal in position 1; foot removed frompedal), continue to inject air into the tire in shortintervals. Check the pressure frequently.

Stand back during bead seat. Keep hands,arms, and entire body away from tire during thisprocedure.

Tire beads should move outward and "pop" intotheir bead seat position as pressure inside thetire increases. If this does not happen, aproblem exists. Investigate carefully.

Check tire pressurefrequently. Neverexceed 40 PSI while

seating beads. Once seated, never exceed tiremanufacturer's recommended air pressure. Tirescan explode, especially if they are inflatedbeyond their limits. At all pressure levels wheninflating through the valve stem, keep hands,arms, and entire body away from inflating tire.An exploding tire, wheel, or bead sealingequipment may propel upward and outward withsufficient force to cause serious injury or deathto operator or bystander.

InflationNEVER exceed tirem a n u f a c t u r e r ' srecommended air

pressure. Tires can explode, especially if inflatedbeyond these limits. Keep hands, arms, andentire body back from inflating tire. Avoiddistraction during inflation. Check tire pressurefrequently to avoid over inflation. Excessivepressure can cause tires to explode, causingserious injury or death to operator or bystander.

1. Make sure both beads are seated. When bothbeads are seated, the tire is ready for inflation.

2. Replace the valve core if it was removed.

3. Depress the inflation pedal to position 2 toinflate the tire. The pressure limiter will cycle theair flow as described earlier. On most passengercar tires, the pressure limiter will cease air flowat approximately 60 PSI. On smaller volumetires, the limiter pressure may be higher.

NOTE: Release air pressure from the tire bypressing the manual release valve button (inflationhose must be attached to the valve stem).Figure 16 -

PERFORMANCE, CUSTOM, ANDALUMINUM WHEELS

Only tire technicianswith experience andtraining on custom

wheels should attempt to service expensivecustom alloy or aluminum wheels and high-performance low-profile tires.

Pre-Operation Notes:• Ensure all weights have been removed.

• Assistance will be required on wide wheels.

• Clamp wheel from the outside.

• Use ample lubricant for mount and demounting

• Always review wheel nicks and/or scratcheswith the owner before servicing.

Aluminum and Custom WheelsFollow instructions provided for standard steelwheels, except:

A. After loosening and lubricating both beads,rotate the table top until the clamps are in the12, 3, 6, and 9 o'clock positions.

Figure 17 - Rotate Table Top to 12 O'clock

B. Clamp wheel from the outside. Position rimedge into clamp at 12 o'clock position. Lowerthe wheel and depress the clamp control pedal.Slowly move the clamps inward until theysecurely contact the outside edge of the rim.

TIP: This is usually accomplished by crouchingdown in front of the tire changer, holding thewheel with the right hand, and operating theclamp control pedal with the left hand. Thisallows the operator to watch the clamps as theymove to ensure proper, damage-free clamping.

Performance Tires and Wheels • DemountingFollow these instructions for performance type tiresand wheels, including run-flat t ires and theirassociated wheels, and asymmetrical hump wheels.

1. Remove the valve core and completely deflatethe tire.

2. Pull the bead loosener shoe away from themachine and roll the tire into position against thebumper pads. Position the tire with the valvestem in the 3 o'clock position (in direct line withthe bead loosener shoe). Always loosen thebead on the narrow/mounting side of the wheelfirst (Figures 4 and 18).

Figure 18 - Position Tire for Bead Loosening

NOTE: Wheels with an asymmetrical humphave a larger "ledge" type hump around thewheel except at the valve hole making themmore difficult to mount and demount (Figure 19).

NOTE: Some wheels have a low pressuresensor/transmitter strapped to the wheel. This isespecially true on run-flat tire/wheel systems. Thesensor is positioned directly opposite from the valvestem. To avoid damaging the sensor, always loosenthe top bead at the valve stem first, then loosen thebottom bead at the valve stem, and then continue toloosen the remaining circumference of the beads asnecessary (Figure 20).

Figure 20 - Wheel with Low Pressure Sensor/Transmitter

3. Loosen bottom bead, starting with valve stempositioned directly next to the loosener shoe(Figure 21).

Figure 21 - Loosen Bottom Bead

4. Liberally lubricate the bottom bead of the tire(Figure 22).

Figure 22 - Lubricate Bottom Bead

5. Clamp the wheel to the table top as described initem B on page 9. Always clamp custom wheelsfrom the outside.

6. Lubricate upper bead liberally. Use the beadlifting tool to help push the tire bead down so thebead area is easier to reach.

Figure 23 - Lubricate Upper Bead

7. Move swing arm into place and adjust asdescribed on page 4, steps 7, 8, and 9. Increase thedistance between the demount head and the wheelan additional 1/16 to 1/8 inch with the adjustmentknob. Locate the valve stem directly under thedemount tool before proceeding.

Figure 27 - Remove Drop Center Tools

11. Demount lower bead. In most cases whendemounting performance tires, the lower beadwill be less difficult. Use help to lift, position, andhold t ire. Pay close attention tosensor/transmitter location, and position itdirectly below the demount tool when startingthe lower bead demount procedure.

Figure 28 - Use Help on Lower Bead, Watch Sensor

Performance Tires and Wheels - Mounting1. Lubricate both tire beads liberally. Performance

tires will require more lubrication than standardpassenger car tires.

2. Mount the lower bead. In most cases, the lowerbead will mount easily.

Figure 29 - Mount Lower Bead, Use Lifting Tool

3. Position the valve stem directly across from themount/demount tool for top bead mounting. Liftthe top bead over the rear of the mount head.Use the lifting tool to help push and keep the topbead in the drop center during mounting, or usean optional drop center tool to help hold thebead in the drop center (Figure 29 & 30). Rotatethe wheel in short steps to mount lower bead.

NOTE: Mounting the top bead can be verydifficult when mounting new tires on manyperformance and custom wheels.

Figure 30 - Mount Top Bead

4. Mount the top bead using short rotations of thewheel. As the wheel progresses, a second dropcenter tool should be added to keep the bead inthe drop center.

Figure 31 - Add Second Drop Center Tool

5. On extremely tight tire and wheel combinations,it may be necessary to use the hooked end ofthe bead lifting tool to flip the tire over the rimflange (Figure 32).

Bead SealingA 140 PSI air blast from the table jets creates an aircurtain to aid in bead sealing. Never exceed 10 PSIin the tire during bead sealing. The tire will containabout 2 PSI when bead seal is obtained.

STAGES OF INFLATIONReview these descriptions and diagrams carefully. Refer to them as necessary during bead sealing, beadseating, and inflation to verify that you are proceeding properly and safely.

Bead SeatingBead seating usually occurs on the long taperedside of the wheel first and the shorter side last.Bead seating will usually require at least 7 PSI inthe tire. 40 PSI is the maximum safe pressure atthis stage regardless of operating pressure.

Most European import cars and many aftermarketalloy wheels are very tight and may be difficult tobead seat. Also note that asymmetric hump andrun-flat tires are extremely difficult to bead seat.Follow tire manufacturer's recommended procedurefor bead seating.

InflationAfter the beads are seated, the tire is inflated. Donot inflate the tire above the manufacturer'srecommended pressure as stamped on the tiresidewall. The typical inflation pressure for automobiletires is between 24 and 45 PSI. Light truck inflationpressure typically covers a wider range.

MIS-MATCHED TIRES AND WHEELSNever attempt to mount and inflate mis-matchedtires and wheels.

Requires rubber lubricant onboth upper and lower beads.

Air flow through valverequires about 140PSI air pressure dropto ensure sufficientflow on difficult tires.

Lift tire up to assistseal on top side.

Separator/Lubricator MaintenanceCheck oil and water levels regularly, and performthese maintenance items weekly:

A. Disconnect air supply to machine.

B. Drain water from the separator by unscrewingthe petcock on the bottom of bowl. Allow waterto drain and tighten petcock securely by hand.

C. Add oil to the lubricator if the fluid level is morethan 1/4" from the top of the gauge. Remove thefiller plug on top of the lubricator and add SAE10W non-detergent oil or an air tool oil to bringthe level up to 1/4" from the top of the gauge.Replace filler plug and clean up any spilled oil.

D. Adjust the oil flow by pulling the adjustmentknob up and turning it to increase or decreasethe flow. Push the knob down to lock. Watch theformation of oil drops in the see-through oilchamber. Reconnect the air supply andcontinually cycle the bead loosener through fullstrokes and count the drips during the cycles.The delivery of oil to the air line should be about1 drop per 10 cylinder cycles. Adjust flow asrequired.

Mount/Demount Head CleaningClean dirt and debris from the mount/demount tool(duckhead) roller with small screw driver or pick.
