2. Pull the bead loosener shoe away from the machine
and roll wheel into position. The valve stem should be
in the 2 o’clock position to accommodate a possible
asymmetric safety hump type rim. Position the bead
loosener shoe against the tire next to, but not on, the
rim. Press the bead loosener foot pedal to actuate the
shoe and loosen the bead. It may be necessary to
loosen the bead in multiple locations around the tire
(figure 3).

3. Turn the wheel around and repeat loosening pro-
cedure on the other side of the wheel (figure 4). This

the table top if the long side of the rim is loosened

liberally to entire circumference of both tire beads after
loosening (figure 5).

7. Use Robo-Arm LR with cone to apply pressure to
aid in clamping rim (figure 7). Use the clamp control
pedal to move the clamps inward (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).
