DEMOUNTING TUBE TYPE TIRES
4.2.4 Demount Tube type tires
◇
After both tire beads are loosened, try to remove the tube. If you cannot remove the tube
lubricate the beads and rim liberally.
◇
Position the demount head and bead lifting tool as described earlier paying careful
attention not to pinch the tube. Depress the table top pedal and rotate only a short
distance at a time. This allows you to stop the process should you suspect the tube is
getting pinched.
◇
After upper bead is demount, remove tube and demount lower bead.

or rubber residue. Do not attempt to service heavily corroded wheels.
◇
I
nspect tire for damage, paying close attention to the beads. Verify size match between
tire and wheel.
◇

REMEMBER:
TABLE TOP ROTATION CAN BE STOPPED AT ANY TIME BY REMOVING YOUR FOOT FROM THE ROTA- TION
PEDAL. NORMAL TABLE TOP ROTATION
FOR DEMOUNTING IS CLOCKWISE. DEPRESS THE TABLE TOP PEDAL TO ROTATE THIS DIRECTION. TO
ROTATE THE TABLE TOP COUNTERCLOCKWISE, LIFT THE PEDAL UP WITH
YOUR TOE.
THE RIM AND BEAD MUST BE LIBERALLY LUBRICATED. FAILURE TO USE AN
ADEQUATE LUBRICANT CAN LEAD TO THE BEAD BINDING ON THE RIM AND
LEAD TO DAMAGE TO THE MOTOR AND OR VOID THE WARRANTY.
