3.1 Safety devices
The wheel aligner features a safety device (master switch) on the rear of the machine, see
chap. 3 on page 4. The master switch disconnects power to the machine when positioned
on “O”.
Caution: the measuring heads are powered by the lift unit. These can be switched off and on by
means of the control on the unit itself (see lift manual).
