Demounting

1. Place the master roller on the tire shoulder and turn
the rim-chuck plate to lubricate the area between
tire bead and rim channel.
2. While turning, lubricate the area between the bead
and the drop center using a brush and tire bead
lubricant.
3. Use the master roller to push the tire far enough
down to allow the mounting head to be inserted
between rim and tire.

4. Put the lifting lever between the edge of the tire and
the rim, taking advantage of the space created by
the pressure of the main roller.
5. Lift the master roller off the tire.
6. Place the helper on the opposite side of the tire
(relative to the mounting head) and move the helper
downward so that the bead slips into the drop cen-
ter of the rim.
