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.11).

B. Break both beads.
Hold open the Bead Breaker, roll the tire/rim into the
Breaker area (Fig. 12). Ensure that the Tire/rim assem-
bly is 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 easy to
mistakenly keep your foot on the bead breaking pedal
too long. This could potentially result in bead or rim
damage

NOTICE !
ON “RUN FLAT” TYPE WHEELS 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 WILL RE-
SULT 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 ex-
pand 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.
