WARNING
Operator Protective Equipment
Personal protective equipment helps make tire
changing safer. However, equipment does not take
the place of safe operating practices. Always wear
durable work clothing during tire service activity.
Shop aprons or shop coats may also be worn,
however 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.

Operating Instructions
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.
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 back side of wheel may
cause the wheel to be clamped unlevel. This may
result in the combination mount/demount head
contacting the rim causing scratches. On alloy
wheels, always rotate the wheel one turn after
setting the head to insure proper wheel chucking.
B. Always review nicks and scratches with owners of
expensive wheel and tire combinations prior to
servicing.
C. 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).
Figure 1 – Remove Valve Core to Deflate Tire
NOTE: 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.
D. Always loosen the bead on the narrow side of
the wheel’s drop center first. See Figure 4 for
more information on the drop center.
E. 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.
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 3 o’clock position.
Position the bead loosener shoe against the tire
next to, but not on, the rim. Press the button on
the bead loosener to actuate the shoe and
loosen the bead. It may be necessary to loosen
the bead in multiple locations around the tire
(Figure 2).
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 (see
Figure 4).
G. 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 3).
Figure 3 – Apply Rubber Lubricant to Tire Beads

CAUTION
5. 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.)
Figure 4 – Determining Mounting Side of Wheel
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 steel wheels from the inside (clamps
push outwards against wheel). Clamp mag and
custom wheels from the outside (clamps push
inwards against the outside rim edge). Refer to
the Performance Tires and Wheels section.
Figure 5 – Place Tire/Wheel Assembly on Table Top
7. Move the swing arm into position. Pull the
locking handle forward to release the slide.
Push down on the top of the vertical slide to
move the demount head 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 head will move upward
approximately 1/8 inch from rim edge (Figure 6).
Figure 6 - Position
Mount/Demount Tool
8. The mount/demount head roller should be in
contact with the rim edge. Turn the swing arm
adjusting knob to move the roller away from the
rim 1/8 to 1/4 inch (Figure 7).
Figure 7 - Adjust Swing Arm to Position Head Roller
9. Check head positioning. Mount/demount head
should be positioned with 1/8 to 3/16" clearance
between the top of the rim edge and the bottom
of the head, and 1/8 to 1/4 inch clearance
between the rim edge and the head roller. 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 head (when changing
a like set of wheels) (Figure 8).
Figure 8 - Proper Mount/Demount Head Position
Figure 8A – Depicts proper mount/demount
head positioning with the standard 6060 head.
Figure 8B – For additional protection on
decorative wheels, the nylon "bootie" (part
#182963) should be used. The clearance may
also be reduced when using the "bootie."
Figure 8C – For maximum protection on
decorative wheels, the optional nylon head
should be used (part #182960). This head
replaces the metal head. The vertical locking
mechanism "lift" feature must also be reduced to
1
⁄
16".
H. The vertical tool clearance may change with
machine use and should be inspected often.
Failure to maintain the proper clearance may
result in damage to the wheel rim and/or tire.
