H.
The tool clearance may change with machine use and
should be inspected often. Failure to maintain the proper
clearance may result in damage to the wheel rim and/or tire.
J.
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.
K.
Table top rotation can be stopped at any time by re-
moving your foot from the rotation pedal.
At times during the mounting and demounting pro-
cedure, the bead lifting tool may encounter resistance and
can be thrown. Keep one hand firmly on the tool to avoid
possible tool disconnect. Use the reversing feature to back
out of jam-ups. A thrown tool can cause injury.
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. Lift the bead up and over the knob on the Mounting
head (figure 10). Also, note the valve stem position to the
Mounting head. Use your free hand to press down on the tire
opposite the Mounting head to allow the bead to utilize the
drop center area of the rim, this position reduces stresses in the
bead and allows an easier bead lift.

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.
Hold the tool and bead in this position (figure 11).
Figure 11 - Lift Bead Over Demount Head
12. Depress the table top pedal to rotate the wheel. The
Mounting head will guide the tire bead up and over the edge
of the wheel. Continue rotation until the upper bead is de-
mounted.
L.
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 10).
Figure 12 - Demounting Lower Bead
13. Lift and hold the tire at an angle so that the lower bead
is resting in the drop center directly across from the de-
mount head, and is loose below the demount head (figure
12). 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 13).
Figure 13 - Guide Lower Bead Over Tool Head
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 de-
mounted.
M.
With tube-type tires, demount the upper bead and
remove the tube before demounting the lower bead.
