4.5 Stop brake
Figure 4-22 Pedal of wheel stop brake
Activate the pedal to brake the wheel holder chuck
and make fixing nut clamping or unclamping easier.
The wheel is also retained in the correct position to
allow for an easier weight application.
Warning:
This stop brake is designed only to facilitate
orientation of the wheel and must not be used for
braking the chuck during operation.
The pedal also controls the Power Clamp, for clamping
the wheel on the balancer.
 Lift the pedal so as to clamp or unclamp the wheel.
 Press the pedal to engage the brake and stop the
chuck.
4.6 Clamping a wheel
Fig. 5-17
The main shaft lock pedal has two functions:
A
PEDAL DOWN: Stopping rotation.
POWER CLAMP lock
PEDAL UP:
The pedal in addition to the brake has a control function
for the POWER CLAMP device (and the wheel Lifter
if present), for clamping and removing the wheel on/
from the balancer.
Each time the pedal is moved UP, the Power Clamp
alternatively releases or clamps the wheel on the
balancer.
Only for models with wheel lifter:
The platform of the lifter (if present) is operated
by the pedal simultaneously with the POWER
CLAMP command and moves vertically to
support the wheel. The platform DESCENDS
during wheel clamping, then RISES during
wheel release.
