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

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 5 - Place Tire/Wheel Assembly on Table Top

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 approxi-

mately 1/8 inch from the

rim edge.

Figure 6 - Position Mount/
Demount Tool

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.

Figure 7 - Adjust Swing Arm to Position Tool Roller

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. 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.
