BEAD BREAKING

Preliminary checks

Check on the pressure gauge of the filter regulator + lubricator unit that there is a pres-
sure of at least 8 bar.
Check that the machine has been hooked up to the electrical mains correctly.

Switching on the machine

Power up the machine using the green master switch 1 fig.9d on the lid of the electrical box.
To switch on the machine, press the master switch to the -I- (ON) position. The master
switch illuminates to indicate that the machine is powered up.
If the machine is inactive after a sudden power drop, the message "ATT" appears on the
Display fig. 9a. To re-enable operation of the machine if the power blackout has occurred
during operation, the head tools and the units with bead breaker disc must be removed
from the working area.
ATTENTION
In these conditions, if the reset procedure is triggered accidentally, the movement can
be stopped by pressing one of the four "Wheel dimension" keys on the display panel.
The message "STP" will appear and a beeper will sound; all the machine's controls
can now be used in "manual" mode to restore normal working status.
Press any of the numerical value input keys on the Keypad 4 - Fig. 9a. The turntable and
the two units with bead breaker disc automatically reset in the radial position suitable
for processing 26" rims.
The machine is now ready to accept new settings and restart subsequent jobs.
Important note: during this operation, with the machine/support plate on the 26" setting,
once the reset microswitch is tripped the support plate moves back by about 1" before
restarting the reset operation.
How to decide the side of the wheel from which
to demount the tyre
See fig.10
Find the position of the drop centre A on the wheel rim. Find the largest width B and
the smallest width C.
The tyre must be demounted or mounted with the wheel positioned on the turntable
with the side with the smallest width C facing upward.

Special instructions

Some types of wheels on the market require special procedures and precautions which
differ from the standard procedure.
This applies in particular to the following types of wheels:
Alloy rim wheels: some wheels have alloy rims where the drop centre A is very small or
non-existent - fig. 10a. These rims are not approved to DOT (Department of Transportation)
criteria - the marking which certifies the tyre's conformity to the safety standards adopted
by the United States and Canada (these wheels cannot be sold on these markets).
