Special Instructions For Demounting
Extremely Wide Motorcycle Tires (RC200)
101. First review the large decal located on the
tower of the changer. Read and understand the informa-
tion.
102. On very wide motorcycle tires (over 8-inches
wide) it may be advantageous to remove the motor-
cycle clamps from the machine and replace with three
position automotive clamps.
The automotive three position clamps are accessories
and can be ordered as p/n 818113125C for four clamps.
Also, the plastic protection booties are recommended
and can be ordered as p/n 8183604 for 10.
103. As with motorcycle clamps, after bead loosen-
ing and before clamping the wheel, preposition the
clamps.

Protective Booties
104. With the tire bead loosened from the rim, posi-
tion the wheel in the center of the table clamping sys-
tem. If the sidewalls are extremely stiff, the Robo Arm™
may be placed in the center of the wheel (protect the
surface with rag) and press the wheel down with the
RoboArm to assist in clamp engagement. Activate the
clamps slowly and observe rim clamping.
105. To assist in positioning the duckhead at the
location near the rim, use the Robo Arm to press the
tire sidewall down.
106. Lubricate the upper bead surface. To assist,
position the manual roller assembly into the receiver.
Press down and the roller between the rim and the tire
bead. This will allow easy lubrication of the upper bead
surface and rim flange.
