4.0 MOUNTING AND DEMOUNTING
PRECAUTIONS
IMPORTANT!
BEFORE MOUNTING A TIRE ON A RIM, PAY AT-
TENTION 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 CEN-
TERING. BE SURE YOU ARE USING APPROVED
LUBRICANT ONLY.
F. MAKE SURE THE TIRE IS THE CORRECT SIZE
FOR THE RIM.

4.0.1 Angular tool adjustment

The tool is adjusted at the factory with an optimal angle
for most wheels used today. However, the angle can
be optimised for wheels with a diameter that diff ers
considerably from the standard.
To adjust the tool angle, proceed as follows (Fig. 10):
1 Mount the rim for which the adjustment is required.
2 Loosen the lower screw (1).
3 Adjust the tool with the screws shown (2a and
2b). Unscrew the screw 2a or 2b to rotate the tool,
respectively clockwise or counterclockwise.
4 Screw in the opposite screw to block the tool in the
desired angular position.
5 Tighten the lower screw (1) with a torque of 35 Nm.

4.1 DEMOUNTING TUBELESS TIRES

A. Remove all wheel-weights from the rim. Remove
the valve stem or valve stem core and defl ate the tire
(Fig.11).
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 as-
sembly 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 is easy to mistakenly keep your foot on the
bead breaking pedal too long. This could po-
tentially result in bead or rim damage (Fig.12)

NOTICE !
ON VEHICLES WITH TPMS SENSORS, BREAK THE
BEAD AT 90 DEGREES OFFSET FROM THE VALVE
STEM. DAMAGE TO THE WHEEL AND/OR SENSOR
WILL RESULT IF THE BEAD IS BROKEN AT ANY
OTHER POINT ON THE RIM.
