Bead Loosening
1. After locking the wheel on the chuck, remove the
valve core and deflate the tire completely.
2. Position the bead loosening disc in one of the
square holes in the carriage closest to the outer edge
of the tire.
3. Rotate the tire. While the tire is rotating, slowly
advance the bead loosening disc to contact the tire
bead. Adjust the chuck up or down so the disc is close
to the rim.
Do not contact the rim with the bead loos-
ening disc. Damage to the rim may result.
4. Once the rim edge is cleared, the chuck may be
lowered to move the disc closer to the tire bead.
Continue moving the disc toward the machine until the
bead is loosened.
5. While the tire is still rotating, apply a liberal
amount of tire lubricant to the tire bead and the rim.
6. Raise the chuck and back the tool away from the
tire, being careful not to contact the rim.
7. Move the bead loosening disc to the rear of the
tire and repeat the steps above to loosen the rear
bead.
Note: Tire lubricant is very important in the demount-
ing and mounting process. While the bead loosening
tool is pushing the bead away from the rim edge, lib-
erally lube both beads and the rim. FAILURE TO APPLY
LUBE COULD RESULT IN DAMAGE TO THE TIRE
BEAD.
Note: Applying a liberal amount of lube to the tire
sidewall prior to bead loosening will make the tire
more pliable and therefore reduce the likelihood of
damage to the sidewall.
Demounting
1. If the rim has an inclined edge of 15 degrees, con-
tinue the bead loosening procedure for the rear bead
until the tire has been pushed off the rim.
The bead opposite the disc must be in the
drop center of the rim. Damage to the bead
may occur if the bead is not in the drop cen-
ter.
2. If the rim has no edge, or has a stiff sidewall,
retract the disc and remove it from the carriage. Place
the combo tool and tee into position near the outer rim
edge.
