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 may operatedifferently from machinesyou have previously

operated. Practice with a regular steel wheel andtire combination to familiarize yourself with themachine’s operation and function.

A. Remember to remove all weights from both sidesof the 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.

B. Always review nicks and scratches with owners ofexpensive wheel and tire combinations prior toservicing.

C. Review the performance wheel section of thismanual prior to servicing performance tire/wheelcombinations.

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.

D. Always loosen the bead on the narrow side ofthe wheel’s drop center first. See Figure 4 formore information on the drop center.

E. The clamps on the table top may extendbeyond the table top itself. To avoid damagingthe clamps, move them to their full inwardposition before positioning a tire for beadloosening.

F. 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 2 o’clock posit ion.Position the bead loosener shoe against the tirenext to, but not on, the rim. Press the loosenerpedal to actuate the shoe and loosen the bead.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 3).

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

4. Determine the mounting side of the wheel. Themounting side is the narrow side of the dropcenter (Tire removed in Figure 3 for clarity).

Figure 3 – Determine Mounting Side of Wheel

5. Place tire/wheel assembly on table top withmounting side up (Figure 4). Use the clampcontrol pedal to move the clamps inwards (pushpedal down) or outwards (toggle pedal up).

Figure 4 – Place Tire/Wheel Assembly on Table Top

Clamp steel wheels from the inside (clamps pushoutwards against wheel). Clamp mag andcustom wheels from outside (Clamps pushinwards against the outside rim edge). Refer tothe Performance Tires and Wheels section.

Figure 5 - Apply Rubber lubricant to the beads

6. Apply tire manufacturer’s approved rubberlubricant liberally to entire circumference of bothbeads after loosening and placing on table top.Using L.H. & R.H. helpers to hold down topbead while rotating wheel and lower lift disk forbottom bead will make lubrication easier (Figure5).

Figure 6 - Position Mount/Demount Tool

7. Move the tower forward into position. Pull thelocking valve button forward to release the slides.The vertical slide will descend. Pull the slide handleto move the demount head into contact with the rimedge. Push the locking valve button to lock theslides into place. As the slides are locked, themount/demount head wil l move upwardapproximately 1/8 inch and backward 1/8 inch fromthe rim edge. (Figures 6 & 7)

Figure 7 - Adjust Slides to Position Head Roller

8. The mount/demount head roller should not be incontact with the rim edge & the flat area under thehead should be raised above rim flange (figure 7).

Figure 8 - Proper Mount/Demount Head Postion

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 the slidelocking valve remains locked. The operator maymove the tower back out of the way and backinto place again without needing to repositionthe head (when changing a like set of wheels)(Figure 8).

H. The tool clearance may change with machineuse and should be inspected often. Failure tomaintain the proper clearance may result indamage to the wheel rim and/or tire.

11. Raise the right hand helper roller up and pushthe bead lifting tool down toward the wheel tolift the tire bead up and over the knob portion ofthe demount head (Figure 10).

Figure 11 - Demount Upper Bead

12. Depress the table top pedal to rotate the wheelclockwise. Leave the left hand helper in postionopposite the demount head and allow it to followthe wheel rotation to assist the bead into dropcenter while demounting. Raise it off the tire asdemounting nears completion (Figure 11).

13. Lift and hold the tire at an angle so that thelower bead is resting in the drop center directlyacross from the demount head. If the tire islarge/wide or has become stuck on the lowerpart of the rim, the L.H./R.H. lower helper disksmay be used to unstick and raise the tire so it iseasier to work (Figure 12).

Figure 12 - Demounting Lower Bead

14. Insert smooth curved end of the bead lifting toolover the clockwise end of demount head andbelow the lower bead of the tire. Lift the beadup and over the knob on the demount head(Figure 13).

15. Depress the table top pedel to rotate the wheel.The demount head will quide the bead up andover the edge of the wheel. Continue rotationuntil the lower bead is demounted. The helperdisks sould be removed during rotation. Swingthem out of the way to complete demounting.

Figure 13-Guide Lower Bead over Tool Head

K. With tube-type tires, demount the upper bead andremove the tube before demounting the lower bead.

L. Table top rotation can be stopped at any time byremoving your foot from the rotation pedal.

M. 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.

The bead lifting tool mayencounter resistance orcome under load at timesduring the mount and

demount procedures. Keep one hand firmly onthe tool to avoid possible tool disconnect. Usethe reversing feature to back out of jam ups.

After successfully completing thedemount process, proceed to Mounting(page 6).

CAUTION

MOUNTING

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

Check tire and wheelcarefully before mounting.Make sure the tire bead

diameter and wheel diameter match exactly.Consult the Rubber Manufacturer's Associationfor approved rim widths for tire sizes.

Attempts to force a beadseat on mis-matched tiresand wheels can cause the

tire to violently explode, causing seriouspersonal injury or death to operator and/orbystanders.

Never mount a tire andwheel handed to you byanyone without checking

both tire and wheel for damage andcompatibility. Be extra cautious of personswithout knowledge of tire service. Keep by-standers out of service area.

Never mount a damagedtire. Never mount a tire ona rusty or damaged wheel.

Damaged tires and/or wheels may explode.If you damage the tirebead during mounting,STOP!, remove the tire

and mark it as damaged. Do not mount adamaged tire.1. Inspect the wheel closely for damage. Clean the

wheel and remove any light corrosion or rubberresidue (Figure 14). Do not attempt to serviceheavily corroded wheels.

Figure 14 - Inspect and Clean the Wheel

2. Inspect tire for damage, paying close attentionto the beads. Verify size match between tire andwheel (Figure 14).

3. Lubricate t ire beads l iberally with t iremanufacturer approved lubricant (Figure 15).

Figure 15 - Lubricate Beads

4. Place tire over wheel and move tower arm intoposition. Position tire so that the lower bead isabove the rear extension of the mount/demounthead and below the front knob (Figure 16).

Figure 16- 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.

Figure 17 - Mounting Top Bead

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 R.H. helper roller, press downon the tire near the mount head. With L.H.helper, press down on the tire near the R.H.roller to hold the tire in the drop center.

NOTE: Move the swirel joint to almost touchvertical shaft. This will eliminate rubbing of thetire sidewall by the L.H. helper arm.

The L.H. helper shoe will follow the tire duringrotation. Depress table top pedal and rotate tireduring rotation. Depress table top pedal androtate tire until the bead is mounted (Figure 17).

Do not force the tire ontothe rim. Bead damagecould result making the

tire unsafe and/or creating the risk of injury.

N. If table top rotation stalls, reverse the table topmomentarily until the tire bead is again loose on thewheel. Reposition the tire on the mount head, makesure the bead is correctly positioned in the dropcenter of the wheel, then attempt mounting again.

P. For tube type tires, mount the lower bead first,move the tower back, install the tube, and thenmount the upper bead.

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 inflationg a u g e o p e r a t i o n .A c c u r a t e p r e s s u r e

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

If the rim has beenclamped from the outsidefor tire mounting, release

the clamps once bead seal is obtained, lift thetire, and move the clamps to the center of thetable top.

Tire failure underpressure is hazardous.This tire changer is not

intended to be a safety device to containexploding tires, tubes, wheels, or bead sealingequipment. Inspect tire and wheel carefully formatch, wear, or defects before mounting. Alwaysuse approved tire bead lubricant duringmounting and inflation.

The inflation pedal, located at the center of the leftside of the machine, controls the flow of air throughthe inflation 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 - Tire Pressure – 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 for beadsealing only. Do not usethis position without a tire

and wheel positioned on the table top. Dirt anddebris could be blown into the air with enoughforce to injure the operator or bystanders. Donot use this position to inflate a tire.

R. The unit is equipped with a pressure limiter toassist the operator with proper tire inflation. Whenthe inflation pedal is held in position 2, the pressurelimiter cycles the machine between position 2(inflation) and position 1 (at rest, no air flow to tire).This cycling helps to prevent over inflation of the tire.Tires can still be over inflated and explode with theuse of this pressure limiter if all of the instructions inthis manual are not followed completely. Thepressure limiter will keep most car and light trucktires from inflating beyond 60 PSI (smaller tires mayreach higher pressures). It is the operator'sresponsibility to follow all instructions and to controlinflation pressure as specified in these instructions.Check the function of the pressure limiter regularlyand maintain it according to the instructionsprovided in this manual for safe and properoperation. Do not tamper with or attempt to adjustthe pressure limiter. Tires requiring inflation beyond60 PSI should be inflated in a safety cage.

Bead Sealing

1. Position valve stem in front of operator andconnect the inflation hose. Hold tire up againstupper edge of the wheel. Be sure tire’s top beadis over the bottom of the valve stem (Figure 18).

Explosion Hazard

Never inflatetire abovemanufacturer'srecommendedpressure after bead isseated.

2. Depress inflation pedal to position 2 and holdabout 1 second to begin air flow through tirevalve, then depress pedal to position 3 and holdbriefly – less than 1 full second. The blast of airfrom the jets will expand tire and seal the beads.

3. Release the inflation pedal and allow it to returnto posit ion 1. Verify that both beads arecompletely sealed to the wheel. Repeat thesesteps if beads have not sealed. It may benecessary to wait a few seconds for the airstorage tank to recover before attempting again.

S. If tire and wheel are properly lubricated andoperator cannot achieve bead seal after 3 or 4attempts, the valve core may be removed from thevalve stem to allow more air flow into the tire toassist with bead seal. After bead seal is achieved,remove the chuck and reinstall the valve core.

Bead SeatingOperator should keephands, arms, and entirebody away from the tireduring the remaining bead

seat and inflation procedures. Do not stand overtire, as personal injury could result.

NEVER increase airpressure to exceed 40 PSIwhen attempting BeadSeat. If operator is unable

to obtain Bead Seat, something is wrong. Deflatetire completely, inspect tire and wheel, correctany problems found, relubricate both tire beads,and reattempt Bead Seal and Seat procedures.Follow all safety instructions in this manual andon 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. Standback during bead seat. Keep hands, arms, andentire body away from tire during this procedure.

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. Never exceed40 PSI while seatingbeads. Once seated,

never exceed tire manufacturer's recommendedair pressure. Tires can explode, especially if theyare inflated beyond their limits. At all pressurelevels when inflating through the valve stem,keep hands, arms, and entire body away frominflating tire. An exploding tire, wheel, or beadsealing equipment may propel upward andoutward with sufficient force to cause seriousinjury or death to operator or bystander.

InflationNEVER exceed tirem a n u f a c t u r e r ' srecommended airpressure. Tires can

explode, especially if inflated beyond theselimits. Keep hands, arms, and entire body backfrom inflating tire. Avoid distraction duringinflation. Check tire pressure frequently to avoidover inflation. Excessive pressure can causetires to explode, causing serious injury or deathto 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 pressure may be higher.

T. Release air pressure from tire by pressing themanual release valve button (inflation hose must beattached to the valve stem, Figure 19).

PERFORMANCE, CUSTOM, ANDALUMINUM WHEELS

Only tire technicians withexperience and trainingon custom wheels should

attempt to service expensive custom alloy oraluminum 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:

AA. After loosening and lubricating both beads,rotate the table top until the clamps are in the12, 3, 6, and 9 o'clock positions (Figure 20).

Figure 20 - Rotate Table Top to 12 O'clock

AB. The table top clamps provide outside clampingof wheels 10 to 21 inches in diameter, andinside clamping of wheels from 12 to 24 inchesin diameter.

Figure 21 - Clamp Wheel (tire removed for clarity)

AC.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(Figure 21).

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 valve core and completely deflate 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 2 o'clock position (above the beadloosener shoe). Always loosen the bead on thenarrow/mounting side of the wheel first (Figures3 and 22).

Figure 22 - Position Tire for Bead Loosening


CAUTION

Valve Stem

AD: Wheels with an asymmetrical hump have alarger "ledge" type hump around the wheel except atthe valve hole making them more difficult to mountand demount (Figure 23).

Figure 23- Asymmetrical Hump Wheel

AE: Some wheels have a low pressuresensor/transmitter strapped to the wheel, othershave a sensor mounted directly to valve stem. Thisis especially true on run-flat tire/wheel systems. Thesensor is positioned directly opposite from the valvestem. To avoid damaging the sensor, always loosenthe top bead with the valve stem at the 2 o’clockposition first, then loosen the bottom bead at thevalve stem, then continue to loosen the remainingcircumference of the beads as necessary (Figure24).

Figure 24 - Wheel with Low Pressure Sensor/Transmitter

3. Loosen bottom bead, starting with valve stempositioned at the 2 o’clock position above thebead loosener shoe (Figure 25).

Figure 25 - Loosen Bottom Bead

4. Liberally lubricate the bottom bead of the tire(Figure 26).

Figure 26 - Lubricate Bottom Bead

5. Clamp the wheel to the table top as described initems AB and AC on page 9. Always clampcustom wheels from the outside.

6. Lubricate upper bead liberally. Use the R.H.helper roller to help push the tire bead down sobead area is easier to reach for lubrication(Figure 27).

Figure 27 - Lubricate Upper Bead

7. Move tower forward into place and adjust asdescribed on page 4, steps 7, 8, and 9. Locatethe valve stem directly under the demount headbefore proceeding (Figure 28).

Figure 28 - Position Valve Stem Under Demount Head

8. Using the R.H. helper roller to hold bead down,insert bead l i f t ing tool between knob ondemount tool and tire bead. Assist the beaddown opposite the demount head by using theL.H. helper shoe on the tire side wall. Raise theR.H. helper roller up and pull the lifting tooldown over the wheel to lift bead up and over theknob on demount head (Figure 29).

9. Hold lifting tool in place and depress the tabletop control pedal momentarily to jog the wheel ashort distance. Check the wheel and tire toverify that operation is not causing damage(Figure 30).

Figure 31 - Jog wheel to remove Top Bead

10. The lifting tool can usually be removed afterjogging the wheel a short distance. Continue tojog the wheel to allow tire to flex where itcrosses the rim edge and slip into drop centeron opposite side. Remove L.H. helper shoewhen about 1/4-1/2 bead is demounted.Continue short rotations untill top bead iscompletely demounted (Figure 31).

Figure 32 - Use helpers on Lower Bead,Watch Senor

11. Demount lower bead. In most cases whendemounting performance tires, the lower beadwill be less difficult. Use helper dics to lift,position, and hold tire. Pay close attention tosensor/ transmitter location, make sure lowerbead is lifted above transmitter (Figure 32) andposition it directly below the demount tool whenstarting the lower bead demount procedure(Figure 32).

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 33 - Mount Upper Bead, using Helpers

3. Position the valve stem directly across from themount/demount tool for top bead mounting. Lift thetop bead over the rear of the mount head. Use theR.H. helper roller to help push and keep the topbead in the drop center during mounting and useL.H. helper shoe hooked over rim edge near theroller to help hold the bead in the drop center(Figures 33 and 34). The helper shoe will follow thewheel while rotating the wheel in short steps andapply extra lubricant to mount upper bead. Removethe R.H. helper roller once bead is well started indrop center.

or

4. Mount the top bead using short rotations of thewheel. This will allow the bead to slip into thedrop center opposite the mounting head (Figure35).

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 36).

Figure 36 - Use Hooked End of Bead Lifting

6. After beads are mounted, follow the detailedinstructions provided in the inflation section ofthis manual for bead sealing, bead seating, andinflation.

CUSTOM AND SPECIAL WHEELS

If a custom wheel isdamaged in mounting ordismounting, STOP, and

avoid damaging the other wheels. Continue onlywhen the cause is identified and corrected.

Alloy WheelsSome manufacturers offerwheels with little or no dropcenter. These are not DOT

approved. The tire or wheel - or both - can bedamaged and the tire could explode under pressure,resulting in serious injury or death. If you attempt tomount/demount this type of wheel, use extremecaution (Figure 37).

STAGES OF INFLATION

Review these descriptions and diagrams carefully.Refer to them as necessary during bead sealing,bead seating, and inflation to verify that you areproceeding properly and safely.

Bead SealingA 140 PSI air blast from the table top jets creates anair curtain to aid in bead sealing. Never exceed 10PSI in the tire during bead sealing. The tire willcontain about 1/2 to 2 PSI when bead seal isobtained.

Bead SeatingBead seating usually occurs on the long taperedside of the wheel first and the shorter side last. Beadseating will usually require at least 7 PSI in the tire.40 PSI is the maximum safe pressure at this stageregardless of tire operating pressure.

Most European import cars and many aftermarketalloy wheels are very tight and can be difficult tobead seat. Also note that asymmetrical 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 t ire above the manufacturer'srecommended pressure as stamped on the tiresidewall. The typical inflation pressure forautomobile tires is between 24 and 45 PSI. Lighttruck inflation pressure typically covers a widerrange.

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

Mis-matched tire andwheel combinations canexplode, causing personal

injury or death to operator and bystanders.

For safety, do not attempt to mount and inflatemis-matched tires and wheels.

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

A. Disconnect air supply to machine.

B. The Separator (Filter) unit is equiped with anautomatic drain and should not normally needdraining.

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 turning the black flowadjustment knob and turning it to increase ordecrease the flow. Watch the formation of oildrops in the see-through oil chamber.Reconnect the air supply and continually cyclethe bead loosener through full strokes and countthe drips during the cycles. The delivery of oil tothe air line should be about 1 drop per 10cylinder cycles. Adjust flow as required.

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

Pressure Limiter MaintenanceThe pressure limiter helps prevent inflation ofstandard size or larger tires or tubes beyond 60 PSIto minimize risk of explosion. This device is for thesafety of the operator and bystanders. Properoperation of the pressure limiter is essential to safeoperation of the machine.

Check operation of the pressure limiter as shownand described below at least monthly:

1. Remove tires and/or wheels from the machine.

2. Connect the inflation hose to an empty servicetank with a pressure gauge (gauge should read0). Use a certified tank with at least 250 PSIpressure rating.

3. Depress inflation pedal to position 1 to start airf low through the hose and into the tank.Maintain a steady pressure for constant flow.

4. Watch the rising pressure on the tank gaugeand the gauge on the machine. Machine gaugeshould cycle between check and inflationpressures while tank gauge climbs steadily. Astank pressure reaches 60 PSI, the pressurelimiter should stop the air flow automatically.Both gauges should read 60 PSI ± 5 PSI.

5. Release inflation pedal. Check manual releasevalve function by pressing the button andreleasing pressure from the tank until it reaches50 PSI. Disconnect inflation hose, and releaseair inside tank.

6. Replace pressure limiter if it fails to cycleproperly during inflation, if it fails to shut airsupply off at 60 PSI, or if it malfunctions in anyother way. Do not operate machine with a faulty

pressure limiter.

Operating a tire changerwith a defective,improperly adjusted, or

by-passed pressure limiter could result in a tireexplosion with severe injury or death to theoperator or bystanders. Always be sure that thepressure limiter is present and is operatingproperly on the machine at all times.

Never inflate tire abovem a n u f a c t u r e r ’ srecommended pressureafter bead is seated.

Pressure limiter is set at 60 PSI. Any requiredinflation above 60 PSI should be performed in aninflation chamber/safety cage or securelymounted on the vehicle if an inflation chamber isnot available. A tire explosion may causepersonal injury or death to operator orbystanders.

READ…Mounting and inflating thewrong size tire can getyou hurt. Read the size onthe tire and make sure itmatches the rim. Be espe-cially careful about puttinga smaller tire on a largerrim, such as a 16-inch tireon a 16.5-inch rim.

Inflation of a mismatchedtire and rim can cause anexplosion.

INSPECT…Before you put any tire ona rim, inspect the rim forrust, tough spots, bentedges, or cracks thatcould prevent the tire fromseating right. If you spotany of these problems,don’t mount the tire untilthe rim has been checkedby your shop foreman.

Inspect the tire for beaddamage.

MOUNT…Once you’ve made sure the tire is OKand the right size and the rim is OK,mount the tire safely. NEVER, everlean over the tire when you’re inflatingit. If a tire does explode, it will gostraight up. You don’t want to be overthe tire if that happens. Also, neverover-inflate the tire, even if the beaddoesn’t seat. Never inflate over 40PSI. If the tire hasn’t seated, some-thing is wrong. Deflate the tire andcheck it and the rim again. If it doesn’twork the second time, try another tire.
