12. Depress the table top pedal to rotate the wheel
clockwise. Leave the left hand helper in postion
opposite the demount head and allow it to follow
the wheel rotation to assist the bead into drop
center while demounting. Raise it off the tire as
demounting nears completion (Figure 11).
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. If the tire is
large/wide or has become stuck on the lower
part of the rim, the L.H./R.H. lower helper disks
may be used to unstick and raise the tire so it is
easier to work (Figure 12).

The demount head will quide the bead up and

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
