WARNING

Operator Protective Equipment

Personal protective equipment helps make tire changing safer. However, equipment does not take the place of safe operating practices. Always wear durable work clothing during tire service activity. Shop aprons or shop coats may also be worn, however loose fitting clothing should be avoided. Tight fitting leather gloves are recommended to protect operator’s hands when handling worn tires and wheels. Sturdy leather work shoes with steel toes and oil resistant soles should be used by tire service personnel to help prevent injury in typical shop activities. Eye protection is essential during tire service activity. Safety glasses with side shields, goggles, or face shields are acceptable. Back belts provide support during lifting activities and are also helpful in providing operator protection. Consdieration should also be given to the use of hearing protection if tire service activity is performed in an enclosed area, or if noise levels are high.

OPERATING INSTRUCTIONS

The unit must be properly operated and properly maintained to help avoid accidents that could damage the unit and injure the operator or bystanders. This section of the Operating Instructions manual review basic operations and use of controls. These instructions should be reviewed with all employees before they are allowed to work with the machine. Keep these instructions near the machine for easy reference.

BEAD LOOSENING AND DEMOUNTING

This machine may operate differently from machines

you have previously operated. Practice with a regular steel wheel and tire combination to familiarize yourself with the machine’s operation and function.

A. Remember to remove all weights from both sides of the wheel. Weights left on back side of wheel may cause the wheel to be clamped unlevel. This may result in the combination mount/demount head contacting the rim causing scratches. On alloy wheels, always rotate the wheel one turn after setting the head to insure proper wheel chucking.

B. Always review nicks and scratches with owners of expensive wheel and tire combinations prior to servicing.

C. Review the performance wheel section of this manual prior to servicing performance tire/wheel combinations.

1. Deflate tire completely by removing the valve

core from the valve stem (Figure 1).

Figure 1 – Remove Valve Core to Deflate Tire

NOTE: Loosening the beads on a partially or fully inflated tire is unsafe and causes excess movement and friction against the bumper pads and excessive wear on pivots. Deflate the tire completely to prolong the life of your machine.

D. Always loosen the bead on the narrow side of the wheel’s drop center first. See Figure 4 for more information on the drop center.

E. The clamps on the table top may extend beyond the table top itself. To avoid damaging the clamps, move them to their full inward position before positioning a tire for bead loosening.

F. Use extra care in positioning the bead loosener shoe on larger wheels/tires, and on alloy wheels. Make sure the shoe rests next to but not on the rim, and not on the tire sidewall.

2. Pull the bead loosener shoe away from the machine and roll wheel into position. The valve stem should be in the 2 o’clock position. Position the bead loosener shoe against the tire next to, but not on, the rim. Press the loosener pedal to actuate the shoe and loosen the bead. It may be necessary to loosen the bead in multiple locations around the tire (Figure 2).

Figure 2 – Position Tire and Bead Loosener Shoe

3. Turn wheel around and repeat loosening procedure on the other side of the wheel. This should be the long side of the drop center (see Figure 3).

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

4. Determine the mounting side of the wheel. The mounting side is the narrow side of the drop center (Tire removed in Figure 3 for clarity).

Figure 3 – Determine Mounting Side of Wheel

5. Place tire/wheel assembly on table top with mounting side up (Figure 4). Use the clamp control pedal to move the clamps inwards (push pedal down) or outwards (toggle pedal up).

Figure 4 – Place Tire/Wheel Assembly on Table Top

Clamp steel wheels from the inside (clamps push

outwards against wheel). Clamp mag and custom wheels from outside (Clamps push inwards against the outside rim edge). Refer to the Performance Tires and Wheels section.

Figure 5 - Apply Rubber lubricant to the beads

6. Apply tire manufacturer’s approved rubber lubricant liberally to entire circumference of both beads after loosening and placing on table top. Using L.H. & R.H. helpers to hold down top bead while rotating wheel and lower lift disk for bottom bead will make lubrication easier (Figure

5).

Figure 6 - Position Mount/Demount Tool

Move the tower forward into position. Pull the locking valve button forward to release the slides. The vertical slide will descend. Pull the slide handle to move the demount head into contact with the rim edge. Push the locking valve button to lock the slides into place. As the slides are locked, the mount/demount head will move upward approximately 1/8 inch and backward 1/8 inch from the rim edge. (Figures 6 & 7)

Figure 7 - Adjust Slides to Position Head Roller

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

Figure 8 - Proper Mount/Demount Head Postion

9. Check head positioning. Mount/demount head

should be positioned with 1/8 to 3/16" clearance between the top of the rim edge and the bottom of the head, and 1/8 to 1/4 inch clearance between the rim edge and the head roller. This clearance will be maintained as long as the slide locking valve remains locked. The operator may move the tower back out of the way and back into place again without needing to reposition the head (when changing a like set of wheels) (Figure 8).

H. The tool clearance may change with machine use and should be inspected often. Failure to maintain the proper clearance may result in damage to the wheel rim and/or tire.

Figure 9 - Insert Bead Lifting Tool

10. Move Left Hand top helper into postion opposite demount head and press down on sidewall of the tire to help bead into drop center. Move Right Hand top helper roller into position and press down on sidewall to help tool insertion. Insert smooth curved end of lift tool over the clockwise end of demount head and below the top bead of the tire (Figure 9).

Figure 10 - Lift Bead over Demount Head

11. Raise the right hand helper roller up and push the bead lifting tool down toward the wheel to lift the tire bead up and over the knob portion of the demount head (Figure 10).

Figure 11 - Demount Upper Bead

12. Depress the table top pedal to rotate the wheel clockwise. Leave the left hand helper in postion opposite the demount head and allow it to follow the wheel rotation to assist the bead into drop center while demounting. Raise it off the tire as demounting nears completion (Figure 11).

13. Lift and hold the tire at an angle so that the lower bead is resting in the drop center directly across from the demount head. If the tire is large/wide or has become stuck on the lower part of the rim, the L.H./R.H. lower helper disks may be used to unstick and raise the tire so it is easier to work (Figure 12).

Figure 12 - Demounting Lower Bead

14. Insert smooth curved end of the bead lifting tool over the clockwise end of demount head and below the lower bead of the tire. Lift the bead up 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 and over the edge of the wheel. Continue rotation until the lower bead is demounted. The helper disks sould be removed during rotation. Swing them out of the way to complete demounting.

Figure 13-Guide Lower Bead over Tool Head

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

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

M. Normal table top rotation for demounting is clockwise. Depress the table top pedal to rotate this direction. To rotate the table top counterclockwise, lift the pedal up with your toe.

The bead lifting tool may encounter resistance or come under load at times

during the mount and demount procedures. Keep one hand firmly on the tool to avoid possible tool disconnect. Use the reversing feature to back out of jam ups.

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

MOUNTING

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

Check tire and wheel carefully before mounting.

Make sure the tire bead diameter and wheel diameter match exactly. Consult the

Rubber Manufacturer's Association

for approved rim widths for tire sizes.

Attempts to force a bead

seat on mis-matched tires

and wheels can cause the tire to violently explode, causing serious personal injury or death to operator and/or bystanders.

Never mount a tire and

wheel handed to you by

anyone without checking both tire and wheel for damage and compatibility. Be extra cautious of persons without knowledge of tire service. Keep bystanders out of service area.

Never mount a damaged

tire. Never mount a tire on

a rusty or damaged wheel.

Damaged tires and/or

wheels may explode.

If you damage the tire

bead during mounting, STOP!, remove the tire and mark it as damaged. Do not mount a damaged tire.

1. Inspect the wheel closely for damage. Clean the

wheel and remove any light corrosion or rubber residue (Figure 14). Do not attempt to service heavily corroded wheels.

Figure 14 - Inspect and Clean the Wheel

2. Inspect tire for damage, paying close attention

to the beads. Verify size match between tire and wheel (Figure 14).

3. Lubricate tire beads liberally with tire

manufacturer approved lubricant (Figure 15).

Figure 15 - Lubricate Beads

4. Place tire over wheel and move tower arm into position. Position tire so that the lower bead is above the rear extension of the mount/demount head and below the front knob (Figure 16).

Figure 16- Position Tire Against Mount/Demount Head

5. Depress table top pedal and rotate the wheel to mount the lower bead. Use the drop center of the wheel to reduce the tensional force on the bead by pressing down on the tire directly across from the mount head. Rotate table top until lower bead is fully mounted.

Figure 17 - Mounting Top Bead

6. For top bead, rotate the table top until the valve stem is directly across from the mount head. Lift the upper bead up and over the rear of the mount head. With R.H. helper roller, press down on 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 touch

vertical shaft. This will eliminate rubbing of the tire sidewall by the L.H. helper arm.

The L.H. helper shoe will follow the tire during

rotation. Depress table top pedal and rotate tire during rotation. Depress table top pedal and rotate tire until the bead is mounted (Figure 17).

Do not force the tire onto the rim. Bead damage could result making the

tire unsafe and/or creating the risk of injury.

N. If table top rotation stalls, reverse the table top momentarily until the tire bead is again loose on the wheel. Reposition the tire on the mount head, make sure the bead is correctly positioned in the drop center 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 then mount the upper bead.

INFLATION

Tire inflation is performed in three steps: Bead Seal, Bead Seat, and Inflation. These steps are explained in detail on page 13. Read the explanation of each step and understand them thoroughly before proceeding.

Check for proper inflation gauge operation.

Accurate pressure readings are important to safe tire inflation. Refer to the Operating Maintenance section of this manual for instructions.

If the rim has been

clamped from the outside

for tire mounting, release the clamps once bead seal is obtained, lift the tire, and move the clamps to the center of the table top.

Tire failure under

pressure is hazardous.

This tire changer is not intended to be a safety device to contain exploding tires, tubes, wheels, or bead sealing equipment. Inspect tire and wheel carefully for match, wear, or defects before mounting. Always use approved tire bead lubricant during mounting and inflation.

The inflation pedal, located at the center of the left side of the machine, controls the flow of air through the inflation hose.

NOTE: The clip-on chuck on the end of the hose should always be an open style with all parts in proper working order.

Position 1 - Tire Pressure – With the inflation hose

attached to the tire valve and the pedal in this position, the air gauge will register the air pressure in the tire. Whenever your foot is removed from the pedal, it will return to this position.

Position 2 - Tire Inflation – This is the first activated position. With the inflation hose attached to the tire valve and the pedal in this position, line pressure is allowed to flow through the valve and into the tire for inflation. Tire pressure is not indicated on the gauge in this position.

Position 3 - Bead Sealing – This is the second and last activated position. With the inflation hose attached to the tire valve and the pedal in this position, line pressure is allowed to flow through the valve and to the air-flate bead seal jets on the table top for bead sealing.

Use Position 3 for bead sealing only. Do not use

this position without a tire and wheel positioned on the table top. Dirt and debris could be blown into the air with enough force to injure the operator or bystanders. Do not use this position to inflate a tire.

R. The unit is equipped with a pressure limiter to assist the operator with proper tire inflation. When the inflation pedal is held in position 2, the pressure limiter 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 the use of this pressure limiter if all of the instructions in this manual are not followed completely. The pressure limiter will keep most car and light truck tires from inflating beyond 60 PSI (smaller tires may reach higher pressures). It is the operator's responsibility to follow all instructions and to control inflation pressure as specified in these instructions. Check the function of the pressure limiter regularly and maintain it according to the instructions provided in this manual for safe and proper operation. Do not tamper with or attempt to adjust the pressure limiter. Tires requiring inflation beyond 60 PSI should be inflated in a safety cage.

Bead Sealing

1. Position valve stem in front of operator and

connect the inflation hose. Hold tire up against upper edge of the wheel. Be sure tire’s top bead is over the bottom of the valve stem (Figure 18).

Page 10

Explosion Hazard

Never inflate tire above manufacturer's recommended pressure after bead is seated.

2. Depress inflation pedal to position 2 and hold about 1 second to begin air flow through tire valve, then depress pedal to position 3 and hold briefly – less than 1 full second. The blast of air from the jets will expand tire and seal the beads.

3. Release the inflation pedal and allow it to return to position 1. Verify that both beads are completely sealed to the wheel. Repeat these steps if beads have not sealed. It may be necessary to wait a few seconds for the air storage tank to recover before attempting again.

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

Bead Seating

Operator should keep hands, arms, and entire body away from the tire

during the remaining bead seat and inflation procedures. Do not stand over tire, as personal injury could result.

NEVER increase air

pressure to exceed 40 PSI

when attempting Bead

Seat. If operator is unable to obtain Bead Seat, something is wrong. Deflate tire completely, inspect tire and wheel, correct any problems found, relubricate both tire beads, and reattempt Bead Seal and Seat procedures. Follow all safety instructions in this manual and on machine.

1. Once tire pressure is indicated on the air gauge

(inflation pedal in position 1; foot removed from pedal), continue to inject air into the tire in short intervals. Check the pressure frequently. Stand back during bead seat. Keep hands, arms, and entire body away from tire during this procedure.

Tire beads should move outward and "pop" into their bead seat position as pressure inside the tire increases. If this does not happen, a problem exists. Investigate carefully.

Check tire pressure frequently. Never exceed 40 PSI while seating

beads. Once seated, never exceed tire manufacturer's recommended air pressure. Tires can explode, especially if they are inflated beyond their limits. At all pressure levels when inflating through the valve stem, keep hands, arms, and entire body away from inflating tire. An exploding tire, wheel, or bead sealing equipment may propel upward and outward with sufficient force to cause serious injury or death to operator or bystander.

Inflation

NEVER exceed tire

manufacturer's

recommended air

pressure. Tires can explode, especially if inflated beyond these limits. Keep hands, arms, and entire body back from inflating tire. Avoid distraction during inflation. Check tire pressure frequently to avoid over inflation. Excessive pressure can cause tires to explode, causing serious injury or death to operator or bystander.

1. Make sure both beads are seated. When both

beads 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 to

inflate the tire. The pressure limiter will cycle the air flow as described earlier. On most passenger car tires, the pressure limiter will cease air flow at approximately 60 PSI. On smaller volume tires the pressure may be higher.

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

• 9010A/E Rim Clamp Tire Changer

DANGER

Explosion Hazard

Never exceed 40 PSI while seating beads.

WARNING

DANGER

IMPORTANT: When inflating tires that require more than 60 PSI, always use a safety cage and air hose with a

clip-on air chuck and in-line valve. The hose must have enough length between the chuck and the operation/inline valve to allow the operator to stand outside the trajectory.

PERFORMANCE, CUSTOM, AND ALUMINUM WHEELS

Only tire technicians with experience and training

on custom wheels should attempt to service expensive custom alloy or aluminum wheels and high-performance lowprofile 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 scratches

with the owner before servicing.

Aluminum and Custom Wheels

Follow instructions provided for standard steel wheels, except:

AA.After loosening and lubricating both beads,

rotate the table top until the clamps are in the 12, 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 clamping

of wheels 10 to 21 inches in diameter, and inside clamping of wheels from 12 to 24 inches in diameter.

Figure 21 - Clamp Wheel (tire removed for clarity)

AC.Clamp wheel from the outside. Position rim

edge into clamp at 12 o'clock position. Lower the wheel and depress the clamp control pedal. Slowly move the clamps inward until they securely contact the outside edge of the rim (Figure 21).

TIP: This is usually accomplished by crouching down in front of the tire changer, holding the wheel with the right hand, and operating the clamp control pedal with the left hand. This allows the operator to watch the clamps as they move to ensure proper, damage-free clamping.

Performance Tires and Wheels • Demounting

Follow these instructions for performance type tires and wheels, including run-flat tires and their associated wheels, and asymmetrical hump wheels.

1. Remove valve core and completely deflate tire.

2. Pull the bead loosener shoe away from the machine and roll the tire into position against the bumper pads. Position the tire with the valve stem in the 2 o'clock position (above the bead loosener shoe). Always loosen the bead on the narrow/mounting side of the wheel first (Figures 3 and 22).

Figure 22 - Position Tire for Bead Loosening

9010 Rim Clamp Tire Changer •

CAUTION

Valve Stem

Page 12

AD: Wheels with an asymmetrical hump have a larger "ledge" type hump around the wheel except at the valve hole making them more difficult to mount and demount (Figure 23).

Figure 23- Asymmetrical Hump Wheel

AE: Some wheels have a low pressure sensor/transmitter strapped to the wheel, others have a sensor mounted directly to valve stem. This is especially true on run-flat tire/wheel systems. The sensor is positioned directly opposite from the valve stem. To avoid damaging the sensor, always loosen the top bead with the valve stem at the 2 o’clock position first, then loosen the bottom bead at the valve stem, then continue to loosen the remaining circumference of the beads as necessary (Figure

24).

Figure 24 - Wheel with Low Pressure Sensor/Transmitter

3. Loosen bottom bead, starting with valve stem positioned at the 2 o’clock position above the bead 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 in items AB and AC on page 9. Always clamp custom wheels from the outside.

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

Figure 27 - Lubricate Upper Bead

7. Move tower forward into place and adjust as described on page 4, steps 7, 8, and 9. Locate the valve stem directly under the demount head before proceeding (Figure 28).

Figure 28 - Position Valve Stem Under Demount Head

8. Using the R.H. helper roller to hold bead down, insert bead lifting tool between knob on demount tool and tire bead. Assist the bead down opposite the demount head by using the L.H. helper shoe on the tire side wall. Raise the R.H. helper roller up and pull the lifting tool down over the wheel to lift bead up and over the knob on demount head (Figure 29).

9. Hold lifting tool in place and depress the table top control pedal momentarily to jog the wheel a short distance. Check the wheel and tire to verify that operation is not causing damage (Figure 30).

Figure 31 - Jog wheel to remove Top Bead

10. The lifting tool can usually be removed after jogging the wheel a short distance. Continue to jog the wheel to allow tire to flex where it crosses the rim edge and slip into drop center on opposite side. Remove L.H. helper shoe when about 1/4-1/2 bead is demounted. Continue short rotations untill top bead is completely demounted (Figure 31).

Figure 32 - Use helpers on Lower Bead,Watch Senor

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

Performance Tires and Wheels - Mounting

1. Lubricate both tire beads liberally. Performance tires will require more lubrication than standard passenger car tires.

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

Figure 33 - Mount Upper Bead, using Helpers

3. Position the valve stem directly across from the

mount/demount tool for top bead mounting. Lift the top bead over the rear of the mount head. Use the R.H. helper roller to help push and keep the top bead in the drop center during mounting and use L.H. helper shoe hooked over rim edge near the roller to help hold the bead in the drop center (Figures 33 and 34). The helper shoe will follow the wheel while rotating the wheel in short steps and apply extra lubricant to mount upper bead. Remove the R.H. helper roller once bead is well started in drop center.

Figure 34 - Mounting Top Bead

AF: Mounting the top bead can be very difficult when mounting new tires on performance and custom wheels. Proceed slowly and cautiously.

Figure 35

9010 Rim Clamp Tire Changer •

Sensor

Page 14

4. Mount the top bead using short rotations of the wheel. This will allow the bead to slip into the drop center opposite the mounting head (Figure

35).

5. On extremely tight tire and wheel combinations, it may be necessary to use the hooked end of the bead lifting tool to flip the tire over the rim flange (Figure 36).

Figure 36 - Use Hooked End of Bead Lifting

6. After beads are mounted, follow the detailed instructions provided in the inflation section of this manual for bead sealing, bead seating, and inflation.

CUSTOM AND SPECIAL WHEELS

If a custom wheel is damaged in mounting or

dismounting, STOP, and avoid damaging the other wheels. Continue only when the cause is identified and corrected.

Alloy Wheels

Some manufacturers offer

wheels with little or no drop

center. These are not DOT approved. The tire or wheel - or both - can be damaged and the tire could explode under pressure, resulting in serious injury or death. If you attempt to mount/demount this type of wheel, use extreme caution (Figure 37).

Figure 37 - No Drop Center

European Performance Wheels (Asymmetrical

Hump)

Some European wheels have very large humps except near the valve hole. On these wheels, the beads should be loosened at the valve hole on both the upper and lower sides first (Figure 38).

Figure 38 - Asymmetrical Hump on European Wheels

Wheels with Low Pressure Warning Sensors

Performance wheels on some vehicles (including Corvette, BMW, Lamborghini Diablo) have a pressure sensor strapped to the rim opposite the valve hole. On these wheels, the beads should be loosened at the valve hole on both upper and lower sides first (Figure 39).

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 are proceeding properly and safely.

Bead Sealing

A 140 PSI air blast from the table top jets creates an air curtain to aid in bead sealing. Never exceed 10 PSI in the tire during bead sealing. The tire will contain about 1/2 to 2 PSI when bead seal is obtained.

Bead Seating

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

Most European import cars and many aftermarket alloy wheels are very tight and can be difficult to bead seat. Also note that asymmetrical hump and run-flat tires are extremely difficult to bead seat. Follow tire manufacturer's recommended procedure for bead seating.

Inflation

After the beads are seated, the tire is inflated. Do not inflate the tire above the manufacturer's recommended pressure as stamped on the tire sidewall. The typical inflation pressure for automobile tires is between 24 and 45 PSI. Light truck inflation pressure typically covers a wider range.

MIS-MATCHED TIRES AND WHEELS

Never attempt to mount and inflate mis-matched tires and wheels.

Mis-matched tire and wheel combinations can explode, causing personal

injury or death to operator and bystanders.

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

Before making any inspection, adjustment, or

repair, disconnect the power source and block out all moving parts to prevent injury.

Keep the machine and the

immediate work area

clean. Do not use compressed air to remove dirt and debris from the machine. Foreign material may be propelled into the air and into operator or bystander causing personal injury.

Wear protective clothing

and use eye protection

when making any adjustments or repairs to the machine.

A. The vertical and horizontal slides and the helper

slides should be cleaned with a vaporizing solvent and then lubricated with chassis grease once a month.

B. Check the adjustment of the mount/demount

head once a month. See instructions this page.

C. The transmission in this machine is a sealed

unit packed with grease and should need no normal maintenance.

D. The table top, clamps, steel mount/demount

head, and other working surfaces should be cleaned with a vaporizing solvent every month.

E. The clamps should be inspected and metal

chips and dirt removed from the serrations with a wire brush once a month.

F. Check the tire pressure gauge function daily,

and check the accuracy monthly. Use a pressurized tire and a high quality stick-type pressure gauge. If necessary, adjust the dial of the machine gauge. If the gauge is defective, replace it immediately (part number 107985). Contact COATS at (615) 641-7533. Check function of the pressure limiter weekly. Always reinstall the lens after adjusting the gauge.

G. Make sure all fasteners are securely tightened.

H. Make certain that all guards and covers are in

place.

I. Check for worn, damaged or missing parts

including grips and protective covers. Replace them before allowing the unit to be used.

J. On a daily basis, inspect the unit and check to

be certain that all systems are operating normally. Detailed inspection and testing procedures are specified for various components at regular intervals. Set up a chart and assign responsibility for these items.

Separator/Lubricator Maintenance

Check oil and water levels regularly, and perform these maintenance items weekly:

A. Disconnect air supply to machine.

B. The Separator (Filter) unit is equiped with an

automatic drain and should not normally need draining.

C. Add oil to the lubricator if the fluid level is more

than 1/4” from the top of the gauge. Remove the filler plug on top of the lubricator and add SAE 10W non-detergent oil or an air tool oil to bring the 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 flow

adjustment knob and turning it to increase or decrease the flow. Watch the formation of oil drops in the see-through oil chamber. Reconnect the air supply and continually cycle the bead loosener through full strokes and count the drips during the cycles. The delivery of oil to the air line should be about 1 drop per 10 cylinder cycles. Adjust flow as required.

Mount/Demount Head Cleaning

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

Pressure Limiter Maintenance

The pressure limiter helps prevent inflation of standard size or larger tires or tubes beyond 60 PSI to minimize risk of explosion. This device is for the safety of the operator and bystanders. Proper operation of the pressure limiter is essential to safe operation of the machine.

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

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

2. Connect the inflation hose to an empty service tank with a pressure gauge (gauge should read

0). Use a certified tank with at least 250 PSI pressure rating.

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

4. Watch the rising pressure on the tank gauge and the gauge on the machine. Machine gauge should cycle between check and inflation pressures while tank gauge climbs steadily. As tank pressure reaches 60 PSI, the pressure limiter should stop the air flow automatically. Both gauges should read 60 PSI ± 5 PSI.

5. Release inflation pedal. Check manual release valve function by pressing the button and releasing pressure from the tank until it reaches 50 PSI. Disconnect inflation hose, and release air inside tank.

6. Replace pressure limiter if it fails to cycle properly during inflation, if it fails to shut air supply off at 60 PSI, or if it malfunctions in any other way. Do not operate machine with a faulty pressure limiter.

Operating a tire changer with a defective, improperly adjusted, or

by-passed pressure limiter could result in a tire explosion with severe injury or death to the operator or bystanders. Always be sure that the pressure limiter is present and is operating properly on the machine at all times.

Never inflate tire above

manufacturer’s

recommended pressure

after bead is seated. Pressure limiter is set at 60 PSI. Any required inflation above 60 PSI should be performed in an inflation chamber/safety cage or securely mounted on the vehicle if an inflation chamber is not available. A tire explosion may cause personal injury or death to operator or bystanders.

TIRE FAILURE UNDER PRESSURE IS HAZARDOUS! This tire changer Will Not Restrain Exploding Tires, rims or other related equipment.

TIRES CAN EXPLODE, ESPECIALLY IF INFLATED BEYOND SPECIFIED LIMITS. DO NOT EXCEED TIRE MANUFACTURERS RECOMMENDED AIR PRESSURE.

AN EXPLODING TIRE, RIM, OR BEAD SEATING EQUIPMENT MAY PROPEL UPWARD AND OUTWARD WITH SUFFICIENT ENERGY TO CAUSE SERIOUS INJURY OR DEATH TO OPERATOR AND/OR BYSTANDERS.

READ…

Mounting and inflating the wrong size tire can get you hurt.

Read

the size on the tire and make sure it matches the rim. Be especially careful about putting a smaller tire on a larger rim, such as a 16-inch tire on a 16.5-inch rim.

Inflation of a mismatched tire and rim can cause an explosion.

INSPECT…

Before you put any tire on a rim,

inspect

the rim for rust, tough spots, bent edges, or cracks that could prevent the tire from seating right. If you spot any of these problems, don’t mount the tire until the rim has been checked by your shop foreman.

Inspect

the tire for bead

damage.

MOUNT…

Once you’ve made sure the tire is OK and the right size and the rim is OK,

mount

the tire safely. NEVER, ever lean over the tire when you’re inflating it. If a tire does explode, it will go straight up. You don’t want to be over the tire if that happens. Also, never over-inflate the tire, even if the bead doesn’t seat. Never inflate over 40 PSI. If the tire hasn’t seated, something is wrong. Deflate the tire and check it and the rim again. If it doesn’t work the second time, try another tire.

1. Damaged Bead or Beads.

2. Rusty Wheels.

(particularly in the bead seat area)

3. Bent or Cracked Wheels.

4 A. Mismatched.

(A mis-match of a 16inch tire to a 16.5inch rim causing an explosion)
