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.

bar or lock to hold position.
13. Rotate tire and rim while moving bead loosener
roller slowly upward using hand valve. Continue bead
loosening until roller has pushed bead near the drop
center of wheel.

valves.
2. Inspect tire and liner; next lubricate tire beads and
liner beads. Use ample amount of lubricant.
3. Position the tire/liner over rim and place duckhead
at the rim’s top edge; next position bottom bead of tire
