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 AND PAINT IT AFTER REMOVING ALL
WHEEL-WEIGHTS TO INCLUDE '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 care and deflate the tire (Fig.14).
B. Break both beads.
Hold open the Bead Breaker, roll the tire/rim into the
Breaker area (Fig. 15). Ensure that the Tire/rim assembly
is against the rubber breaker pad 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.15).
