Pay extra attention during this operation as it easy to
mistakenly keep your foot on the bead breaker pedal too
long. This could result in immediate bead damage.
C. Set the rim clamps to the proper position: retract
clamps to clamp the wheel from the inside and expand
clamps to clamp from the outside.
Clamping the wheels from the outside set the clamps
at diameter nearly equal to the rim diameter, before
placing the wheel on the clamps. This will avoid the
risk of pinching the tire.
(1,5mm)
D. Liberally lubricate both beads.
Place the wheel WITH DROP CENTER UP (Fig. 4.1-4)
on the turntable, and clamp in position. Hold the tire
and wheel down while clamping.
E. Gently position the mount/demount head in contact
with the rim edge and lock it into place: the tool
automatically moves away from the rim edge vertically.
Turn the adjustment knob until the mount/demount
head clears from the rim fl ange about 1/16" (2 mm):
this is necessary to avoid rim damage (Fig. 4.1-5).
MAINTENANCE NOTE:
IF THE MOUNT/DEMOUNT HEAD NYLON INSERTS
ARE WEARING OUT PREMATURELY, THE CAUSE
IS THE OPERATOR'S FAILURE TO CORRECTLY
SET THE RIM DIAMETER ADJUSTMENT KNOB,
CAUSING THE INSERT TO INCORRECTLY
CONTACT THE RIM.
WARNING
ON CHEVROLET CORVETTE WHEELS WITH
THE OPTIONAL LOW PRESSURE SENSOR
INSTALLED, BREAK THE BEAD AT 90 DEGREES
OFFSET FROM THE VALVE STEM. DAMAGE
TO THE WHEEL WILL RESULT IF THE BEAD IS
BROKEN AT ANY OTHER POINT ON THE RIM.
WARNING: TO MINIMIZE THE RISK OF
SCRATCHING ALLOY RIMS, THESE SHOULD
BE CLAMPED FROM THE OUTSIDE
NOTE:
The plastic insert inside the mount/demount tool
must be periodically replaced. Every
machine is equipped with several plastic
inserts (inside standard equipment box).
If desired, a steel roller also included in
the standard equipment box may replace
the plastic insert. Follow the instructions
included with the replacement parts.
