3. Rotate the wheel counterclockwise while main-
taining pressure on the spade tool until the outer bead
is demounted. Push the valve stem inside the rim and
pull the inner tube out of the tire.
Note: It is possible to roll one or both beads(s) off the
rim with the bead loosener disc instead of the combo
tool. However, care must be taken not to damage the
tube or the valve stem. By alternately rotating the
wheel first counterclockwise, then clockwise, being
careful not to pass over the valve stem, the tire may be
demounted using this method. If the tire is wide, the
rim is thin or weak, or the side wall is tough, do not use
this method since the bead or the rim may be dam-
aged.
Note: Tire lubricant greatly reduces the force needed
to demount or mount a tire. Liberally lube each bead
and rim edge while the bead loosener disc holds the
bead away from the rim. FAILURE TO APPLY LUBE
COULD RESULT IN DAMAGE TO THE TIRE BEADS.
Mounting
1. Lube both beads and the rim liberally.
2. Rotate the rim so the valve stem hole is directly
on the bottom, then roll the wheel onto the carriage.
3. Move the combo tool into position near the edge
of the rim.
Note: Mounting of the outer bead is shown in order
to see the position of the tools. Position of the tools
will be the same for the inner bead.
4. Lean the tire against the rim and clamp the vise
grip on the edge of the rim to the left of the combo
tool. Rotate the chuck to lift off the carriage.
5. Using one of the tire tools to assist the bead into
drop center, continue rotating the chuck until the inner
bead is mounted.
6. Insert the inner tube and repeat the above steps
to mount the outer bead.
Note: Avoid damage to the valve stem by never
allowing the stem to pass the stationary tool.
