Operator Protective Equipment
Personal protective equipment helps make tire servicing safer. However, equipment does not take the place of safe operating practices. Always wear durable work clothing during tire service activity. 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. Consideration 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.

Remember R.I.M.
Three Simple Steps To Help Keep Shops Safe
READ INSPECT MOUNT
R.I.M. is a training program developed by Hennessy Industries to help keep tire technicians safe. By following the basic principles of R.I.M., technicians can avoid situations that can cause catastrophic accidents like tire explosions.
R.I.M. stands for read, inspect, and mount: Read the tire size on a new tire before mounting to make sure it is the proper size for the wheel. Inspect the wheel for cracks, rust, and or other damage that could cause an unsafe situation. Mount the tire safely, making sure not to put any part of your body over the tire during inflation. The most serious of possible accidents is a tire explosion. This is often caused by a tire/rim mismatch. If a tire explodes on a tire changer, pressure causes it to fly straight up at tremendous speed. If a technician is standing over the tire, he can be seriously injured or killed. Hennessy’s R.I.M. program allows the technician to avoid situations that can cause tire explosions and other accidents. The full program, including training videos, brochures, posters, and other materials, is available from Coats distributors nationwide.
For more details, contact your Coats distributor or e-mail us.

Important: Always read and follow operating instructions.

Operating Instructions
This unit must be properly operated and properly maintained to help avoid accidents that could injure the operator or bystanders, or damage the unit. 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.
Tire Bead Loosening and Demounting
CAUTION
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.
NOTE: Remember to remove all weights from both sides of the wheel. Weights left on backside of wheel may cause the wheel to be clamped unleveled. This may result in the combination mount/demount tool contacting the rim causing scratches. On alloy wheels, always rotate the wheel one turn after setting the Duckhead mount/ demount tool to insure proper wheel clamping.
NOTE: Always review with the owner any nicks and scratches on expensive wheel and tire combinations prior to servicing.
NOTE: Review the performance wheel section of this manual prior to servicing performance tire/ wheel combinations.
CAUTION
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.
1. Deflate the tire completely by removing the valve core from the valve stem (figure 1). Be cautious and do not smoke as a flammable gas could have been introduced into the tire at some time.

Figure 1 – Remove Valve Core to Deflate Tire
CAUTION
Tires are always installed and removed from the rim’s narrow side. NOTE: Always loosen the bead on the narrow side of the wheel’s drop center first (tire removed in figure 2 for clarity).

Important: Always read and follow operating instructions.

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

1. Before any mounting, inspect tire for damage and verify size match between tire and wheel (figure 20).

Mounting a mismatched tire and wheel will cause an explosion before it bead seats during inflation. Attempts to force a bead seat, by increasing air pressure, on mismatched tires and wheels will cause the tire to violently explode, causing serious personal injury or death to operator and/or bystanders if standing over tire and wheel.
Check tire and wheel carefully before mounting. Make sure the tire bead diameter and wheel diameter match exactly. Consult the tire manufacturer’s recommendations, Tire Guide and/or Rubber Manufacturer’s Association for approved rim widths for tire sizes.

Figure 20 – Verify Size Match Between Tire and Wheel
2. Inspect wheel closely for damage. Clean the wheel and remove any light corrosion or rubber residue (figure 21). Do not attempt to service a heavily corroded wheel, damaged wheel, or bent wheel.

Never mount a damaged tire. Never mount a tire on a rusty or damaged wheel. Used tires may have bead and/or tread damage. Used rims may have flange damage where the tire/rim was run down the road on a flat tire. Run-flat tires are not meant to be reused! Damaged tires and/or wheels may explode.
CAUTION

Figure 21 – Inspect and Clean the Wheel
3. Inspect valve stem and replace if necessary. Next lubricate tire beads liberally with tire manufacturer’s approved rubber lubricant (figure 22).

When in doubt do not mount. Never mount a tire and wheel handed to you by anyone without checking both tire and wheel for damage and to be certain the sizes match. Used tires may have road hazard damage or mount/demount damage, inspect carefully. Do not let untrained persons operate tire changer and keep bystanders out of service area.

CAUTION

Figure 22 – Lubricate Tire Beads Liberally

Forcing the tire onto the rim can cause bead damage. If you damage the tire bead during mounting, STOP!, remove tire and mark it as damaged. Do not mount a damaged tire.

Important: Always read and follow operating instructions.

Inflation
Tire inflation is performed in three steps: BEAD SEAL, BEAD SEAT, and INFLATION. These steps are explained in detail on page 14. Read the explanation of each step and understand them thoroughly before proceeding.
Tire failure under pressure is hazardous. This tire changer Will Not Restrain Exploding Tires, rims or other related equipment. Inspect tire and wheel carefully for match, wear, damage, or defects before mounting. Always use approved tire bead lubricant during mounting and inflation.
CAUTION
The clip-on chuck allows the operator to keep hands and entire body back from inflating tire. The chuck must be an open/ freeflow style with all parts in proper working order.
CAUTION
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.

The inflation pedal, located at the rear of the left side of the machine, controls the flow of air through the inflation hose, and has two positions.

Note: The clip-on chuck on the end of the hose is a safety item that must always be an open/freeflow 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 (using the clip-on chuck) to the tire valve and the pedal in this position, line pressure is allowed to flow through the valve system and into the tire for inflation. Correct tire pressure is not indicated on the gauge in this position.

Inflation Pedal Positions
Note the Inflation Pedal Positions (See Diagram)
NOTE: This 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 system between position 2 (inflation) and position 1 (at rest, no airflow to tire). This cycling helps to prevent over inflation of the tire. Tires can still be over inflated and explode, when using 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.

Important: Always read and follow operating instructions.

Bead Sealing
1. Remove the valve core from the valve stem to allow more air flow into the tire to assist with bead seal.
2. Position valve stem in front of operator and connect the inflation hose with the clip-on chuck. Hold tire up against upper edge of the wheel. Be sure tire’s top bead does not cover the bottom of the valve stem (figure 27).

Bead Seating
NEVER exceed 40 PSI to seat beads while using this tire changer. If more than 40 PSI is permitted by tire manufacturer, ALWAYS use safety cage and clip-on chuck. NEVER exceed recommended pressure after seating beads. ALWAYS keep hands and entire body back 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.

Figure 27 – Lift Tire Upwards for Bead Sealing 3. Depress inflation pedal to position 2 and hold to
begin air flow through tire valve. 4. If tire beads do not seal, then use the Auxiliary
Bead Sealer (ABS), see figure 28. 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 pressure to recover before attempting again.
Figure 28 – If Necessary, Use ABS for Bead Sealing 5. After bead seal is achieved, remove the clip-on
chuck and reinstall the valve core. Reattach the clip-on chuck after core is installed.

Check tire pressure frequently. 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 (inflation pedal position 2) in short intervals. Check the pressure frequently. Stand back during bead seat. Keep hands, arms, and
entire body away from tire during this procedure (figure 29).
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.
Important: Do not continue to add air pressure to force bead seat.

Inflation
NEVER exceed tire manufacturer’s recommended air pressure. Tires can explode, especially if inflated beyond these limits. Use clip-on air chuck, 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.

Manual Release Valve
Figure 30 – Location of Manual Release Valve

If you change tires defined as truck tires, they must be inflated per OSHA instructions.
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 tires, the pressure limiter will cease air flow at approximately 60 PSI. On smaller volume tires the pressure may be higher.
4. Release air pressure from tire by pressing the manual release valve button (inflation hose must be attached to the valve stem, Figure 30). Never add or adjust tire pressure using an air hose without a clip-on air chuck and in-line valve. Do not use a hand-held style chuck (figure 31).
5. 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 air hose must have enough length between the chuck and the operation/in-line valve to allow the operator to stand outside the trajectory.

Stages of Inflation on a Conventional Tire and Rim
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
Bead sealing is the process of capturing air pressure between the tire and the rim. The tire will usually contain about 1/2 to 2 PSI at initial bead seal.
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. For tires requiring more than 40 PSI to bead seat use safety cage.
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 ready to be 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.

Important: Always read and follow operating instructions.

· 17

Mismatched Tires and Wheels
Never mount and inflate mis-matched tires and wheels.
Mismatched tire and wheel combinations will explode, if you attempt to force a bead seat, causing personal injury or death to operator and/or bystanders.

Important: Always read and follow operating instructions.

Custom and Special Wheels
CAUTION
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.
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. Do not mount/demount this type of wheel (figure 32).
No Drop Center

Tube Type Tires
Mounting
1. Avoid pinching or forcing the tube.
2. Apply rubber lubricant to the beads of the tire.
3. Mount the bottom bead.
4. Round out the tube with a small amount of air.
5. Apply rubber lubricant to the tube.
6. Insert the tube into the tire.
7. Mount the top bead.
Demounting
1. After tire beads are loosened, lubricate the beads and rim liberally.
2. Position demount tool and bead lifting tool as described in steps 8 through 12 on pages 5 and 6. Depress rotation pedal and rotate only a short distance at a time. This allows you to stop the process should the tube get pinched.
3. After upper bead is demounted, remove tube and demount lower bead.

Pressure Limiter Maintenance
Operating a tire changer with a defective, improperly adjusted, or by-passed pressure limiter could cause an operator to accidentally over pressurize a tire, resulting 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.
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.
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 (should read 0). Use a tank with at least 200 PSI pressure rating.
3. Depress inflation pedal to position 1 to start airflow 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 airflow 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.

Separator/Lubricator Maintenance
Check oil and water levels regularly, and perform these maintenance items weekly:
1. Disconnect air supply to machine.
2. The Separator (Filter) unit is equipped with an automatic drain and should not normally need draining.
3. If the fluid level is more than 1/4″ from the top of the gauge, add oil. Remove the filler plug on top of the lubricator and add SAE10W 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.
CAUTION
Use only SAE 10W non-detergent oil or an air tool oil for seperator/lubricator maintenance. Do not use substitutes like brake fluid, WD-40®, Marvel Mystery Oil®, or antifreeze, as these materials will damage seals within the system.

4. 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 airline should be about 1 drop per
5 to 15 cylinder cycles. Adjust flow as required.
