5.0_REMEMBER R.I.M.
Three Simple Steps To Help Keep Shops Safe
READ INSPECT MOUNT
R.I.M. is a training program developed by HennessyIndustries 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 infl ation.
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 fl y 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.

7.0_DESCRIPTION OF THE MACHINE’S CONTROLS
O
The pedal control (L) is used to move the vertical arm
out of the working position, once the tire has been demounted, or in the working position while mounting and
demounting the tire.
The pedal control (M) is used to turn the spindle fl ange
clockwise, (low and rotation mode) and counter-clockwise
(low rotation mode).
L
N
M
The pedal control (N) is used to lift the tire off the ground to clamp it on the
fl ange and vice versa to lower it back down to the ground after mounting
it. Press the pedal to raise the lift, push the pedal upwards to lower the lift.
The pedal control (O) is used to infl ate the tire. Connect the infl ation hose to the
pneumatic valve and press the pedal to infl ate; to reduce the tire’s pressure, press
the button at the side of the gauge. Before infl ating, read the instruction ma-
nual of the vehicle fi rst to fi nd out the recommended pressure of the tires.
