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.
Definitions of Hazard Levels

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 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 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. Actuate valve to position the bead loosener shoe
away from the machine and roll wheel into position.
The valve stem should be in the 11 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. Actuate the bead
loosener hand valve to position the shoe and loosen
the bead. It may be necessary to loosen the bead in
multiple locations around the tire (figure 3).

Narrow Side
Important: Always read and follow the operating instructions. • 5
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 11 o'clock for the initial loosening procedure to accommodate a possible asymmetric safety hump type rim.
Figure 4 - Position Tire and Bead Loosener Shoe with Wheel
Turned Around
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).
Clamp control pedal must be in the full up
or full down position (detent position) to
maintain clamping force on wheel.
5. Preposition tabletop clamps. Use the clamp con-
trol pedal to move the clamps inward (push pedal
down). Use the clamp control pedal to move the
clamps outward (lift pedal up). Engage the detent position (pedal in full up or full down position) to maintain
clamped or unclamped pedal position.
Avoid back injury, use the tire lift or ask
another operator for assistance when lifting
tire/rim assemblies onto the tire changer.
6. Lift wheel to tabletop or, if equipped, roll
tire/wheel assembly on the tire lift bar. Keep wheel
vertical and press foot pedal to raise wheel up. Now
rotate wheel for placement on tabletop (figure 5).
Figure 5 - Lift Wheel to Tabletop
7. Roll tire/wheel assembly on tabletop with mount-
ing side up (figure 6).
Figure 6 - Clamp Outside on Mag Wheels
Clamp control pedal must be in the full up
or full down position (detent position) to
maintain clamping force on wheel.
8. Use Robo Arm to apply pressure to aid in clamp-
ing rim (figure 7). Use the clamp control pedal to move
the clamps inward (push pedal down). Use the clamp
control pedal to move the clamps outward (lift pedal
up). Engage the detent position (pedal in full up or full
down position) to maintain clamped or unclamped
pedal position.
