The unit must be properly operated and properly
maintained to help avoid accidents that could damage
the unit and injure the operator or bystanders. This sec-
tion 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 instruc-
tions near the machine for easy reference.
Bead Loosening And Demounting
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 to help
prevent damage to rim finishes.
Remember to remove all weights from both sides of
the wheel. Weights left on back side of wheel may
cause the wheel to be clamped un-level. This may
result in the combination mount/demount head con-
tacting the rim causing scratches. On alloy wheels,
always rotate the wheel one turn after setting the head
to insure proper wheel chucking.
Note:
Always review nicks and scratches with own-
ers of expensive wheel and tire combinations prior to
servicing.
Important:
Review the performance wheel section
of this manual prior to servicing performance
tire/wheel combinations.
1.
Deflate tire completely by removing the valve core
from the valve stem (Figure 1).
Figure 1 - Remove Valve Core to Deflate Tire
Note:
Loosening the beads on a fully inflated tire is
unsafe and causes excess movement and friction
against the bumper pads and excessive wear on piv-
ots. Deflate the tire completely to prolong the life of
your machine.
ATV Note:
It may be necessary on ATV wheels to
leave 3-6 PSI in some of these wheels to facilitate
bead loosening. Even after loosening one bead; it may
be necessary to reinflate to 5 PSI to loosen the oppo-
site bead.
Note:
Always loosen the bead on the narrow side of
the wheel's drop center first (motorcycle wheels may
not have a narrow or long side, and some ATV wheels
may may bolt together). See Figure 4 for more infor-
mation on the drop center.
Remember:
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.
Note:
Use extra care in positioning the bead loosener
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.
Pull the bead loosener shoe away from the
machine and roll wheel into position. The valve stem
should be in the 2 o'clock position. Position the bead
loosener shoe against the tire next to, but not on, the
rim. Depress the bead loosener foot pedal to actuate
the shoe and loosen the bead. It may be necessary to
loosen the bead in multiple locations around the tire
(Figure 2).
Figure 2 - Position Tire and Bead Loosener Shoe
3.
Turn wheel around and repeat loosening proce-
dure on the other side of the wheel. This should be the
long side of the drop center.
Tip:
It will be easier to clamp the wheel to the table
top if the lower bead is loosened last.
4.
Apply tire manufacturer's approved rubber lubri-
cant liberally to entire circumference of both tire beads
after loosening (figure 3).
