Operation; Bead Breaking - Nussbaum TC 450 Manual De Instrucciones

ENGLISH • Instructions manual
WARNING!
During all operations, keep hands and other parts of the body as far as possible from moving parts of the machine.
Necklaces, bracelets and too large clothes, can be dangerous for the operator.
WARNING!
Bead breaking must be done with the utmost care and
attention.
When the bead breaker pedal is operated the bead breaker
arm moves quickly and powerfully.
Anything within its range of action can be in danger of
being crushed.
WARNING!
Remember to remove all weights from both sides of the
rim before operating the machine.
1) Deflate the tyre completely and remove the valve core.
2) Close the turntable gripper slides completely.
WARNING!
Bead breaking with the turntable slide grippers open can
crush the operator's hands.
During bead breaking NEVER touch the walls of the tyre
with your hands.
The stroke limiter (see Fig. G/1) is required for bead breaking on RUN FLAT,
LOW PROFILE and UHP tyres.
The device limits the "closure" of the bead breaker by different amounts depending
on the position of the pin (1, Fig. G/1):
- setting "0" : no limitations
- settings 6"-7" ; 8 -9" ; 10"-11" : indicate the rim width for which the bead
breaker closure is set.
Check the rim width and then place the pin in the correct hole: the stroke limiter
will enable bead breaking and prevent the blade from penetrating the tyre sidewalls too far (see Fig. G/2).
N.B.: The stroke limiter must be used with the bead breaker arm set to -10.
3) Open the bead loosener by hand by pushing it towards the outside.
Place the wheel up against the rubber wheel support (13, Fig. E). Bring the blade (14,
Fig. E) against the bead about 1 cm from the edge of the rim (See Fig. G/3).
WARNING! Position the blade as to operate the bead of the
tyre and not of the rim.
4) Push the blade (14, Fig. E) into the tyre by depressing pedal (3, Fig. E).
Repeat this process at different points around the tyre and on both sides until the
beads are completely loosened.
