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).
Figure 2 - Place Spring and Positioning Cone on Post
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.
Figure 3 - Place Wheel on Table Top
4. Place the adapter plate over the center post onto
the wheel with the large side (cushion side) down.
Figure 4 - Place Adapter Plate Over Wheel
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.

6. On models 1010, 1010A, 2020, 2020A, 3030A and
3040A, install the black upper bead loosener protector
on the upper bead loosener nose to protect the wheel
from possible marring by the bead loosener guide.
Place the upper bead loosener shoe on the tire next to,
but not on, the rim. Be sure the top bead loosener
guide is engaged on the rim (figure 6). Depress the
foot pedal until both bead looseners complete their full
strokes. If the top bead is not completely loosened,
release the foot pedal until the machine completes the
full return cycle, then
depress the foot pedal
again. The ratchet effect of
the upper bead loosener will
deliver a deeper stroke.
Important: Use the second stroke only if the upper
bead is not completely loosened by the first stroke.

7. Check detent control knob for proper setting.
Forward is used for all tire and rim combinations
except 15-inch x 4-inch - 4-1/2-inch, 16-inch x 5-inch - 51/2-inch, and 17.5-inch x 5-1/2-inch - 6-1/2-inch.
Relocate detent knob by pushing it down and moving
forward or backward to the proper setting.

8. Install the combination tool end protectors.

9. Demount the tire in the usual manner. Make certain the plastic protector is positioned to completely
cover the end of the tool. Always apply plenty of rubber lubricant to tire beads.

10. Mount the tire in the usual manner. Make certain the plastic protector is positioned to completely
cover the end of the tool. Always apply plenty of rubber lubricant to tire beads.

Small Lower Bead Loosener Shoe
Adjustment
Important: Before attempting to loosen beads, make
sure small lower bead loosener shoe is in adjustment.
1. Clamp a 13-inch, 14-inch, or 15-inch wheel, with-
out tire, on the table top.
2. Depress the foot pedal and cycle the bead
loosener shoe through to the top of its stroke. Watch
closely and inspect the shoe/wheel clearance.
Clearance between the shoe and the wheel rim flange
should be approximately 1/16-inch to 1/8-inch at all
points across the shoe edge. If the clearance is out of
range evenly across the shoe, it can be adjusted. If the
clearance is uneven across the shoe, it has been damaged and must be straightened or replaced.
3. Adjust shoe by loosening the 3/8-inch c 1-1/4-inch
self-tapping bolt located just below the shoes on the
end of the power arm (figure 13). Add or remove shims
turning the small lower shoe into adjustment. Addition
of shims will increase the clearance, and removal of
shims will decrease the clearance. Additional shims
are available.
4. Retighten the self tapping bolt and recheck shoe
adjustment.
Tire failure under pressure can be hazardous. Inspect the tire carefully for wear or
defects before seating or inflating. Never
use pressure beyond the tire industry recommendation of 40 PSI. Always lubricate
with approved lubricant and never damage
beads. Keep hands and entire body back
from inflating or inflated tire.
Special Safety Instructions
1. Never stand with any part of your body over the
tire during inflation process.
2. Before starting, release all air from the tire.
3. Place wheel on the table top with the narrow,
mounting side of the wheel up.
4. Position tire with valve stem directly in front of
operator.
5. Hand tighten hold down cone or adapter before
breaking beads, mounting, or demounting.
6. Use approved lubricant on all beads before seat-
ing, mounting, or demounting.
7. On units with Air-flate, depress inflation pedal only
when seating or inflating the tire.
8. Loosen hold down cone on full turn immediately
after obtaining initial bead seal and before attempting
further inflation.
9. To seat beads, use a small amount of air intermittently. Never exceed tire industry recommendation of
40PSI.
10. During inflation, observe pressure frequently
and avoid distraction to prevent over inflation.
11. When using a bead expander band, do not
exceed 5 PSI in the tire when the band is in place.
