B.
Break both beads.
Hold open the Bead Breaker, roll the tire/rim into the
Breaker area (Fig. 4.1-2). Ensure that the tire/rim
assembly is flat against the rubber breaker pads on
the side of the machine. Make certain that the bead
breaker blade is not over the top of any portion of the
rim. Now activate the bead breaker pedal. As soon
as the bead dislodges from the rim, release the breaker
foot pedal. It may be necessary to rotate the tire 90
degrees and repeat the above procedure to dislodge all
beads.
Pay extra attention during this operation, as it is
easy to mistakenly keep your foot on the bead-
breaking pedal too long. This could potentially result
in bead or rim damage (Fig. 4.1-2)

NOTICE !
ON RUN FLAT TIRES WITH THE OPTIONAL LOW
PRESSURE SENSOR INSTALLED, BREAK THE
BEAD AT 90 DEGREES OFFSET FROM THE VALVE
STEM. DAMAGE TO THE WHEEL AND/OR SENSOR
MAY RESULT IF THE BEAD IS BROKEN AT ANY
OTHER POINT ON THE RIM.
C.
Set the rim clamps to the proper position: retract
clamps to clamp the wheel from the outside and expand
clamps to clamp from the inside.
When clamping small wheels (14" or smaller) from the
outside, set the clamps at a diameter nearly equal to
the rim diameter before placing the wheel on the
clamps. This will help avoid the possibility of pinching
the tire as the clamps retract.
NOTICE !
TO MINIMIZE THE RISK OF SCRATCHING ALLOY
OR CLEAR COATED RIMS, THESE RIMS SHOULD
BE CLAMPED FROM THE OUTSIDE.ô:
D
Position wheel and press it down by hand on the
turntable.
E
Depress pedal through the first position and release.
The wheel is clamped.
4.0 MOUNTING AND DEMOUNTING PRECAUTIONS
IMPORTANT! BEFORE MOUNTING A TIRE ON A
RIM, PAY ATTENTION TO THE FOLLOWING:
A. THE RIM MUST BE CLEAN AND IN GOOD
CONDITION: IF NECESSARY CLEAN IT AFTER
REMOVING ALL WHEEL-WEIGHTS INCLUDING
‘TAPE WEIGHTS’ INSIDE THE RIM.
B. THE TIRE MUST BE CLEAN AND DRY, WITHOUT
ANY DAMAGE TO THE BEAD.
C. REPLACE THE RUBBER VALVE STEM WITH A NEW
ONE OR REPLACE THE ‘O’ RING IF THE VALVE STEM
IS MADE OF METAL.
D. IF THE TIRE REQUIRES A TUBE, MAKE SURE THE
TUBE IS DRY AND IN GOOD CONDITION.
E. LUBRICATION IS NECESSARY TO MOUNT THE
TIRE CORRECTLY AND GET A PROPER CENTERING.
BE SURE YOU ARE USING APPROVED LUBRICANT
ONLY.
F. MAKE SURE THE TIRE IS THE CORRECT SIZE
FOR THE RIM.
4.1 DEMOUNTING TUBELESS TIRES
A.
Remove all wheel-weights from the rim. Remove
the valve stem or valve stem core and deflate the tire
(Fig. 4.1-1).
