BASELINE Tire Changer - Manual (Page 8)

4 • Important: Always read and follow operating instructions.
8. The mount/demount head should be in contact
with the rim edge. Turn the swing arm adjusting knob to
move the mount/demount head away from the rim 1/8
to 1/4 inch (figure 8).
Figure 8 - Adjust Swing Arm to Position Head Roller
9. Check metal head positioning. Mount/demount
metal head should be positioned with 3/16 to 1/8 inch
clearance between the top of the rim edge and the bot-
tom of the head, and 1/8 to 1/4 inch clearance between
the rim edge and the head roller. This clearance will be
maintained as long as the locking handle and adjust-
ment knob are not changed. The operator may swing
the arm out of the way and back into place again
without needing to reposition the head (when changing
a like set of wheels) (figure 9).

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 clock-
wise. 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
removing your foot from the rotation pedal.
CAUTION
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.
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 Duckhead (figure 10). Also, note
the valve stem position to the Duckhead. Use your free
hand to press down on the tire opposite the Duckhead
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).
