10. Insert the smooth curved end of the bead lifting
tool over the forward end of the demount head
and below the top bead of the tire. Use your free
hand to press down on the tire opposite the
head to help with tool insertion (Figure 9).

11. Push the bead lifting tool down towards the
wheel to lift the tire bead up and over the knob
portion of the demount head (Figure 10). The
bead lifting tool may now be removed from
between the tire and the wheel.

12. Depress the table top pedal to rotate the wheel
clockwise. The demount head will guide the
upper bead up and over the edge of the wheel.
J. Push down on the tire across from the
demount head during table top rotation to utilize
the drop center area of the wheel. This reduces
the tensional force on the top or first bead
during demount (Figure 9).
13. Lift and hold the tire at an angle so that the
lower bead is resting in the drop center directly
across from the demount head, and is loose
below the demount head (Figure 11). Insert the
smooth curved end of the bead lifting tool down
over the forward end of the mount/demount tool
and below the lower bead. Lift the bead up and
over the knob on the demount head (Figure 12).

14. Depress the table top pedal to rotate the wheel.
The demount head will guide the bead up and
over the edge of the wheel. Continue rotation
until lower bead is demounted.

K. With tube-type tires, demount the upper bead and
remove the tube before demounting the lower bead.
L. Table top rotation can be stopped at any time by
removing your foot from the rotation pedal.
M. 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 bead lifting tool may
encounter resistance or
come under load at times
during the mount and demount procedures.
Keep one hand firmly on the tool to avoid
possible tool disconnect. Use the reversing
feature to back out of jam ups.
After successfully completing the
demount process, proceed to Mounting
(page 6).
