(
10) OPERATION INSTRUCTION
This unit must be properly operated and properly maintained to help avoid accidents that could injure
the operator or bystanders, or damage the unit. This section of the Operating Instructions manual review
basic operations and use of controls. These instructions should be reviewed with all employees before they are
allowed to work with the machine. Keep these instructions near the machine for easy reference.
This machine may operate differently from machines you have previously operated.
Practice with a regular steel wheel and tire combination to familiarize yourself with the machine’s operation and
function.
A
.
Remember to remove all weights from both sides of the wheel. Weights left on backside of wheel may
cause the wheel to be clamped unleveled. This may result in the combination mount/demount tool contacting
the rim causing scratches. On alloy wheels, always rotate the wheel one turn after setting the Duckhead
mount/demount tool to insure proper wheel clamping.
B.
Always review with the owner any nicks and scratches on expensive wheel and tire combinations
prior to servicing.
C.
Review the performance wheel section of this manual prior to servicing performance tire/wheel com-
binations.
Change a new tire
Loosening the beads on a partially or fully inflated tire is unsafe and
causes excess movement and friction against the bumper pads and excessive
wear on pivots. Deflate the tire completely to prolong the life of your ma-
chine.
1. Deflate the tire completely by removing the valve core from the valve
stem (figure 1). Be cautious and do not smoke as a flammable gas
could have been introduced into the tire at some time.
Tires are always installed and removed from the rim’s narrow
side.
D.
Always loosen the bead on the narrow side
of the wheel’s drop center first (tire removed in figure 2 for clar-
ity).
E.
The clamps on the table top may extend beyond
the table top itself. To avoid damaging the clamps, move them
to their full inward position before positioning a tire for bead
loosening.
F.
Use extra care in positioning the bead loosened
shoe on larger wheels/tires, and on alloy wheels.
Make sure the shoe rests next to but not on the
rim, and not on the tire sidewall.
2. Actuate valve (or pull) to position the bead loosener.shoe away
from the machine and roll wheel into position. The valve stem should be
in the 2 o’clock position to accommodate a possible asymmetric
safety hump type rim. Position the bead loosener shoe against the
tire next to, but not on, the rim. Actuate the bead loosener handle/button
to position the shoe or press the bead loosener pedal to position the
shoe and loosen the bead. It may be necessary to loosen the
bead in multiple locations around the tire (figure 3).
