5.1 Demounting tubeless tires
· Remove all wheel-weights from the rim. Remove the
valve stem or core and defl ate the tire (Fig. 5.1-0).
· Break outer bead starting from opposite the valve
position. lubricate the bead and rim with a tire lube
only. Break inner bead. Do not hold the foot pedal
depressed longer than necessary since this could
damage the bead. Liberally lubricate bead and rim
(Fig. 5.1-1).
WARNING!
ON CARS WITH RUN FLAT TYRES 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.
Locking Rims
· 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. When
clamping small wheels (14" or smaller) 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.
WARNING!
TO MINIMIZE THE RISK OF SCRATCHING ALLOY
RIMS, THESE SHOULD BE CLAMPED FROM THE
OUTSIDE.
· Liberally lubricate bead and rim.
· Place the wheel WITH DROP CENTER UPWARDS
(Fig. 5.1-2) on the turntable, and clamp in position.

5.1.0 Angular tool adjustment

(Fig. 5.1-3)
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:
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.
