3. Position Wheel: Roll wheel onto the safety skirt as
close to the working top as possible. Position rim flange
into the lower clamp.
4. Clamp Rim: With the left hand on the top front of
the rim, push the rim toward the upper two clamps.
Then close the clamping jaws by twisting the control
handle clockwise. Observe the clamping action to make
sure all three clamps are properly engaged. Lower
working table to desired angle by pushing forward on
control handle.
CAUTION
Make sure the short drop center side of the
wheel is toward the operator. Attempting to
demount tire from the long drop center side
may damage the tire bead.
Aluminum Wheels: Many aluminum wheels are
designed for the tire to be mounted from either side.
For these wheels it is recommended to clamp with
the disc side down. However, if the wheel does have
a short drop center side, it should always be clamped
with this side up.
5. Lubricate both beads thoroughly: Both beads and
the rim flange should be thoroughly lubricated with an
approved tire lubricant before attempting to demount
the tire. It may be easier to lubricate the bottom bead
while the tire is in the bead loosener.
Demounting
1. Install Mount/demount Tool: Insert mount/demount
tool in square drive socket and position tool head on the
rim flange. Rotate the tool head to approximately a 12
o’clock position by depressing either foot pedal.
