Figure 9 - Insert Bead Lifting Tool
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 10).
Figure 10 - Lift Bead Over Demount Head
12. Depress the table top pedal to rotate the wheel
clockwise. The demount tool will guide the
upper bead up and over the edge of the wheel.
NOTE: 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 bead during demount.
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 11).
Figure 11 - Demounting Lower Bead
14. Depress the table top pedal to rotate the wheel.
The demount tool will guide the bead up and
over the edge of the wheel. Continue rotation
until lower bead is demounted.
NOTE: With tube-type tires, demount the upper
bead and remove the tube before demounting the
lower bead.
NOTE: Table top rotation can be stopped at any
time by removing your foot from the pedal.
NOTE: 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.
At times during the
mounting and
demounting proce-
dure, the bead lifting tool may encounter resis-
tance or come under load. Keep one hand firmly
on the tool to avoid possible tool disconnect.
Use the reversing feature to back out or jam ups.
After successfully completing the demount
process, proceed to Mounting (page 6).

Operator Protective Equipment
Always wear durable work clothing during tire
service activity. Shop aprons or shop coats may
also be worn, however, loose fitting clothing should
be avoided. Tight fitting leather gloves are
recommended to protect the operator's hands
when handling worn tires and wheels. Sturdy
leather work shoes with steel toes and oil resistant
soles should be used by tire service personnel to
help prevent injury in typical shop activities. Eye
protection is essential during tire service activity.
Safety glasses with side shields, goggles, or face
shields are acceptable. Back belts provide support
during lifting activities and are also helpful in
providing operator protection.
