3. Turn the wheel around and repeat loosening pro-
cedure on the other side of the wheel (figure 4). Note
that the valve is placed at 11 o'clock for the initial loos-
ening procedure to accommodate a possible asym-
metric safety hump type rim.

G. It will be easier to outside clamp the wheel
to the tabletop if the long side of the rim is
loosened last.
4. Determine the mounting side of the wheel. The
mounting side is the narrow side of the drop center
(tire removed in figure 2 for clarity).
Clamp control pedal must be in the full up
or full down position (detent position) to
maintain clamping force on wheel.
5. Preposition tabletop clamps. Use the clamp con-
trol pedal to move the clamps inward (push pedal
down). Use the clamp control pedal to move the
clamps outward (lift pedal up). Engage the detent posi-
tion (pedal in full up or full down position) to maintain
clamped or unclamped pedal position.
Avoid back injury, use the tire lift or ask
another operator for assistance when lifting
tire/rim assemblies onto the tire changer.
6. Lift wheel to tabletop or, if equipped, roll
tire/wheel assembly on the tire lift bar. Keep wheel
vertical and press foot pedal to raise wheel up. Now
rotate wheel for placement on tabletop (figure 5).

Clamp control pedal must be in the full up
or full down position (detent position) to
maintain clamping force on wheel.
8. Use Robo Arm to apply pressure to aid in clamp-
ing rim (figure 7). Use the clamp control pedal to move
the clamps inward (push pedal down). Use the clamp
control pedal to move the clamps outward (lift pedal
up). Engage the detent position (pedal in full up or full
down position) to maintain clamped or unclamped
pedal position.
