Before You Begin
When working on custom wheels, take your time and
use extreme care in all tire servicing operations to prevent damaging these costly wheels. Read and follow all
the instructions and acquaint yourself with this adapter
before use.
Adapter Usage Instructions
1. Before servicing aluminum or magnesium wheels
with a large rim flange, install the 3/16-inch shim to prevent the lower bead loosener from catching on, or damaging the wheel.
To install 3/16-inch Shim: Depress the foot pedal until
the cylinder reaches the top of its stroke. Lay the lower
bead loosener shoe back and place the shim between
the small lower shoe and the shoe adjusting bar (figure
1). When loosening beads on wide flanged rims, watch
the small lower shoe and make certain it clears the rim
flange. If it does not, use the 1/4-inch shim or combine
both shims. Do not use shims on steel wheels.
Figure 1 - Installation of Shim
2. Place the spring and positioning cone over the center post onto the table. The small end of the cone
points upward (figure 2).

3. Place the wheel over the center post onto the
table top, guiding the positioning pin into a lug hole. Be
sure the valve stem is in front of the operator.

4. Place the adapter plate over the center post onto
the wheel with the large side (cushion side) down.

Note: On some high center hub wheels where the
adapter assembly touches the hub of the wheel, the
spacer cushion must be used. Place the cushion on the
wheel, ledge side up, and place the adapter plate on top
of the cushion.
5. Turn the tire changer hold down cone over and
thread it onto the center post. Tighten it down securely
onto the adapter plate. Be sure the hold down cone is
tight.
