BASIC PROCEDURES

For bead loosening with rollers, refer to "Bead Loosening," page 18.
Remove valve stem core and deflate tire completely.
WARNING: All air pressure inside the tire must be removed before
proceeding. Never attempt to loosen the bead until all air
is removed from the tire. Failure to remove all air from
tire may result in injury to operator, or damage to
equipment, tire, or wheel.
Remove all weights from the rim to protect the rim and to extend life of the
mount/demount head.
The lever (pos. 1) allows to operate the bead breaker arm cylinder/side shovel. This
lever has two stable positions with hold control: when the handle is lifted, the side
shovel is pushed into the tire for bead loosening (pos. 2); when the handle is pressed
downward the side shovel opens outwards.
Press the lever downward to make the side shovel open outwards.
Position the wheel against the side of the TC, between the bead breaker arm and the
housing.
Lift the lever. The bead breaker arm will be pulled toward the TC to loosen the bead.
Press the lever downward again to swing the arm to the open position. Once the arm
has been swung to the open position, release the lever.
If the bead has not completely loosened, rotate the wheel and repeat the bead
loosening procedure at a different area on the tire.
Turn the wheel and loosen the opposite bead using the same procedure.
