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.

It Means: Hazards or unsafe practices, which may
result in minor personal injury or product or property
damage.

Watch for this symbol! It means BE ALERT! Your
safety, or the safety of others, is involved!

READ INSPECT

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.

The 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.

Tire Bead Loosening and Demounting

necessary to reinflate to 5 PSI to loosen the opposite
bead.

NOTE: Always loosen the bead on the narrow side of

the wheel’s drop center first (motorcycle wheels may
not have a narrow or long side, and some ATV wheels
may bolt together). See Figure 4 for more information
on the drop center.

REMEMBER: The clamps on the table top may extend

beyond the table top itself. To avoid damaging the
clamps, move them to their full inward position before
positioning a tire for bead loosening.

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.

Remember to remove all weights from both sides
of the wheel. Weights left on back side of wheel may
cause the wheel to be clamped unlevel. 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 tool to insure proper
wheel chucking.

NOTE: Always review nicks and scratches with own­ers of expensive wheel and tire combinations prior to
servicing.

IMPORTANT: Review the performance wheel section
of this manual prior to servicing performance tire/wheel
combinations.

1. Deflate tire completely by removing the valve core

from the valve stem (Figure 1).

NOTE: 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 3 o’clock position. Position the bead loosener shoe
against the tire next to, but not on, the rim. Depress the
bead loosener foot pedal to actuate the shoe and loosen
the bead. It may be necessary to loosen the bead in
multiple locations around the tire (Figure 2).

Motorcycle

Figure 2 - Position Tire and Bead Loosener Shoe

3. Turn wheel around and repeat loosening procedure

on the other side of the wheel. This should be the long
side of the drop center.

ATV

TIP: It will be easier to clamp the wheel to the table

top if the lower bead is loosened last.

4. Apply tire manufacturer’s approved rubber lubricant

liberally to entire circumference of both tire beads after
loosening.

Figure 1 - Remove Valve Core to Deflate Tire

NOTE: Loosening the beads on a 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.

ATV NOTE: It may be necessary on ATV wheels to
leave 3-6 PSI in some of these wheels to facilitate bead
loosening. Even after loosening one bead; it may be

clamp, observe the style and strength of the wheel
and adjust the clamp pressure as necessary using the
pressure regulator and gauge. Thin spun aluminum
rims sometimes used on ATV and motorcycle are
sometimes delicate and a reduced air pressure should
be considered verses cast aluminum and steel wheels
that can support more clamping force.

5b. Next, observe the rim size from the tire, i.e. 15,

16, 17, etc. Using the clamp pedal, place the clamp valve
in the JOG IN position for prelocating the clamps to
the rim diameter. Accomplish this by moving the pedal
from the UP position to the 1/2-DOWN location. Then
JOG the pedal DOWN allowing the clamps to move
inward until the pointer on the clamps align with the rim
diameter on the table top decal. It may be necessary to
relocate the clamps on the clamp carriers. Each clamp
should be in the same position before prelocating the
clamps.

5c. Determine the mounting side of the wheel. The

mounting side is the narrow side of the drop center.
(Tire removed in Figure 4 for clarity.)

7. Move the swing arm into position. Pull the lock-

ing handle forward to release the slide. Push down
on the top of the vertical slide to move the demount

tool into contact with the
rim edge. Push the lock­ing handle back to lock the
slide into place. As the
slide is locked, the mount/
demount tool will move
upward approximately 1/8
inch from the rim edge.

Note: On plastic mount/

demount tool, the upward
movement should be lim­ited to 1/16-inch maximum.

Figure 6 - Position Mount/Demount Tool

8. The mount/demount tool roller should be in contact

with the rim edge. Turn the swing arm adjusting knob
to move the tool away from the rim 1/8 to 1/4 inch.
On expensive and polished rims, it is recommended a
plastic bootie (p/n 8183373) be used over the mount/
demount tool roller.

6. Place tire/wheel assembly on table top with

mounting side up (Figure 5). Use the clamp control
pedal to move the clamps inwards (push pedal down)
or outwards (toggle pedal up). Clamp motorcycle and
ATV wheels from the outside (clamps push inwards
against the outside rim edge). Place rim flange into rear
clamp and slowly move the other clamps inward until
they contact the rim. Observe closely to prevent tire/
wheel damage.

Figure 7 - Adjust Swing Arm to Position Tool Roller

9. Check tool positioning. Mount/demount tool should

be positioned with 1/8 to 3/16” clearance between the
top of the rim edge and the bottom of the tool (with
plastic mount/demount tool it is recommended the ver­tical clearance be limited to a maximum of 1/16-inch),
and 1/8 to 1/4 inch clearance between the rim edge and
the tool. This clearance will be maintained as long as the
locking handle and adjustment knob are not changed.
The operator may swing the arm out of the way and
back into place again without needing to reposition the
tool (when changing a set of the same wheels).

Failure to maintain the proper clearance may result in
damage to the wheel rim and/or tire.

10. Insert the smooth curved end of the bead lifting

tool over the forward end of the demount tool and
below the top bead of the tire. Use your free hand to
press down on the tire opposite the tool to help with
tool insertion (Figure 9).

13. Lift and hold the tire at an angle so that the lower

bead is resting in the drop center directly across from
the demount tool, and is loose below the demount tool
(Figure 11). Insert the smooth curved end of the bead
lifting tool down over the forward end of the mount/
demount tool and below the lower bead. Lift the bead
up and over the knob on the demount tool (Figure 11).

Figure 9 - Insert Bead Lifting Tool

11. Rotate the bead lifting tool down towards the

wheel to lift the tire bead up and over the knob portion
of the demount tool. The tool may be removed if desired
(Figure 10).

Figure 10 - Lift Bead Over Demount Tool

12. Depress the table top pedal to rotate the wheel

clockwise. The demount tool will guide the upper bead
up and over the edge of the wheel.

NOTE: Push down on the tire across from the demount
tool during table top rotation to utilize the drop center
area of the wheel. This reduces the tensional force on
the bead during demount.

The demount tool will guide the bead up and over the
edge of the wheel. Continue rotation until lower bead
is demounted.

NOTE: With tube-type tires, demount the upper bead

and remove the tube before demounting the lower
bead.

NOTE: Table top rotation can be stopped at any time

by removing your foot from the pedal.

NOTE: Normal table top rotation for demounting is

clockwise. Depress the table top pedal to rotate this
direction. To rotate the table top counterclockwise, lift
the pedal up with your toe.

CAUTION

At times during the mounting and demount­ing procedure, the bead lifting tool may
encounter resistance or come under load.
Keep one hand firmly on the tool to avoid
possible tool disconnect. Use the reversing
feature to back out or jam ups.
