4 • Important: Always read and follow operating instructions.

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 mount-
ing side up (Figure 5). Use the clamp control pedal to
move the clamps inwards (push pedal down) or outward
(toggle pedal up). Clamp steel wheels from the inside
(clamps push outward against wheel). Clamp mag and
custom wheels from the outside (clamps push inward
against the outside rim edge). Refer to the Performance
Tires and Wheels section.

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 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.

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.

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, and 1/8
to 1/4 inch clearance between the rim edge and the tool
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
tool (when changing a set of the same wheels).
Figure 8 - Proper Mount/Demount Tool Position
IMPORTANT: 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.
