3. Bead breaking
With the tyre changers a pneumatic tyre bead breaker
is part of the standard equipment.
Please mind the special handling of Run-fl at tires, wheels
with TD rims or rims having an asymmetric hump.
3.1
Bead breaking
Remove the valve insert of the wheel valve.
We would recommend to demount the tyre from the
wide rim shoulder in the fi rst place.
Lean the defl ated wheel on the side against the
special rubber pads provided at the machine
housing.
NOTE: If the tire is over 13" (340 mm) wide, fi rst set the
bead breaker in the "Wide" position as follow:
1) Pull up and hold pin (3,
breaker assembly in the "Wide" position.
2) Insert pin again (3,
Fig.
bead breaker in the new position.
Position the bead breaker blade
outside of the tyre approximately 1 cm away from
the edge of the rim using the adjustable handle for
accurate positioning.
Depress pedal
(2,
Fig. 9). The blade moves in
between tyre and rim. Release the pedal, continue to
rotate the wheel and repeat the breaking procedure
until the tyre has been unseated completely.
Proceed analogously with the second tyre bead.
In order to facilitate subsequent demounting of tyre
and to preserve tyre and rim, it is most useful to apply
a commercial lubricant on tyre and rim at the place
where the bead breaking blade has just penetrated into
the rim base. Never use other agents only supposed
to lubricate!
4. Clamping the wheels
• Before clamping a wheel, release the mounting/
demounting tool (1, Fig. 10), move the mounting/
demounting tool to its highest position, push the
mounting arm fully backwards and lock it again.
Depress the pedal (4, Fig. 10) to tilt the tower (2,
Fig. 10) backwards.
• Clean the wheel and remove the old balancing
weights.
