Take time to experiment with the Duckhead
®
mount/demount tool locking system (figure 8).

Before tilting tower forward, always be sure
Duckhead mount/demount tool is in the
fully retracted position. 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.
9.
Using foot pedal,
position tower forward
(figure 9). See figure
8 for mount/demount
tool movement and
locking. With tower for-
ward, press the slide
lock valve button to
allow mount/demount
tool to descend on the
tire sidewall (figure 9).
Then move the mount/
demount tool toward
rim and release the
locking button.

Demount Tool
10.
Check mount/demount tool positioning. A metal
Duckhead mount/demount tool will move up and back
about 1/8-inch from the rim edge after it is locked. This
clearance will be maintained as long as the slide locking
valve remains locked. The operator may move the tower
back out of the way and back into place again without
needing to reposition the mount/demount tool (when
clamping a like set of wheels).
Note:
If equipped, when positioning the mount/
demount tool toward rim, use disk-assist in upper
position to press down on tire sidewall (figure 10).
Once the bead lifting tool is in place, raise the
Disk-assit off the tire.
At times during the mounting and demount-
ing procedure, 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.
11.
Apply tire manufacturer’s approved rubber lubri-
cant liberally to entire circumference of both beads after
bead loosening and clamping wheel on table top.
Figure 10 - Apply Rubber Lubricant to the Beads
Note:
If equipped, use disk-assist in upper position
to hold down the top bead (figure 10), while rotat-
ing wheel to make tire lubrication easier.
Note:
Normal table top rotation for demounting is
clockwise. Depress table top pedal to rotate this
direction. To rotate table top counterclockwise, lift
pedal up with your toe.
Note:
Table top rotation can be stopped at any time
by removing your foot from the rotation pedal.
12.
Insert the smooth curved end of the bead lifting
tool over the forward end of the demount tool and
below the top bead of the tire. Lift the bead up and over
the knob on the demount tool (figure 11). Also, note the
valve stem position to the demount tool.
