WHEEL SPIN
(VERSION WITH
GUARD)
Wheel spin takes place automatically when
the guard is lowered, or can be triggered
by pressing the START key with the guard
lowered.
A special safety device stops rotation if the
guard is raised during the spin; in this case,
the "A Cr" message is displayed.
WARNING
Do not operate the machine without the
guard and/or if the safety device has been
tampered with.
WARNING
Never raise the guard before the wheel
has come to a stop.
WARNING
If the wheel keeps spinning permanently
due to a fault on the machine, switch off the
machine using the main switch or discon-
nect the plug from the power supply board
(emergency stop) and wait until the wheel
stops before raising the guard.
