Safety Instructions
Owner’s Responsibility
To maintain machine and user safety, the responsibility of the owner is to read and follow these instructions:
• Follow all installation instructions.
• Make sure installation conforms to all applicable
Local, State, and Federal Codes, Rules, and
Regulations; such as State and Federal OSHA
Regulations and Electrical Codes.
• Carefully check the unit for correct initial function.
• Read and follow the safety instructions. Keep them
readily available for machine operators.
• Make certain all operators are properly trained,
know how to safely and correctly operate the unit,
and are properly supervised.
• Allow unit operation only with all parts in place and
operating safely.
• Carefully inspect the unit on a regular basis and
perform all maintenance as required.
• Service and maintain the unit only with authorized
or approved replacement parts.
• Keep all instructions permanently with the unit and
all decals/labels/notices on the unit clean and visible.
• Do not override safety features.
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
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.

Operating Instructions
This 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 reviews
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 backside of wheel may
cause the wheel to be clamped unleveled. This may
result in the combination duckhead®contacting the rim
causing scratches. On alloy wheels, always rotate the
wheel one turn after setting the duckhead to insure
proper wheel chucking.
B. Always review with the owner any nicks and
scratches on expensive wheel and tire combinations
prior to servicing.
C. Review the performance wheel section of this
manual prior to servicing performance tire/wheel combinations.
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 intro-
duced into the tire at some time
.
Figure 1 - Remove Valve Core to Deflate Tire
Tires are always installed and removed from
the rim’s narrow side.
D. Always loosen the bead on the narrow side of the
wheel’s drop center first. See figure 2 for more information on the drop center.
Figure 2 - Determine Narrow Side of Wheel
E. The clamps on the tabletop may extend beyond the
tabletop 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 to accommodate a
possible asymmetric safety hump type rim. 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 3).
Figure 3 - Position Tire and Bead Loosener Shoe
3. Turn the wheel around and repeat loosening pro-
cedure on the other side of the wheel (figure 4). Note
that the valve is placed at 2 o’clock for the initial loosening procedure to accommodate a possible asymmetric safety hump type rim.

G. It will be easier to outside clamp the wheel to the
tabletop if the long side of the rim 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 2 for clarity).
Avoid back injury, seek assistance when lifting heavy tire/rim assemblies onto the tire
changer.
5. Place tire/wheel assembly on tabletop with
mounting side up (figure 5 & 6). Use the clamp control
pedal to move the clamps inward (push pedal down).
Use the clamp control pedal to move the clamps outward (toggle pedal up).

6. Take time to experiment with the duckhead®lock-
ing system (figure 7).
Figure 7 - With Valve Button as Shown, Duckhead Retracks
Up,
Duckhead Descends Slowly, and Duckhead Locks
into Position
Make sure the duckhead is in the retracted
position before moving the tower forward,
to prevent wheel damage.
7. Using the foot pedal, position the tower forward
(figure 8). See figure 7 for duckhead movement and
locking. With the tower forward, allow tool to descend
on the tire sidewall (figure 8). Then move the tool
toward the rim and actuate the locking button. As the
tool locks into place, the duckhead will move up and
back about 1/8-inch.

8. The duckhead should not be in contact with the
rim edge after the duckhead is locked.
