Stop brake
Fig. 4-16
Wheel stop brake pedal
Press the pedal to brake the wheel holder chuck to
make clamping nut locking or unlocking easier.
The wheel is retained in the correction position for
correct fi tting of the balance weights.
Warning
:
This brake is designed only to facilitate orientation
of the wheel and must not be used for braking the
chuck in operation.
Note
:
On the wheel balancers equipped with the quick-
acting
Power Clamp
system, the pedal also controls
the
Power Clamp
, for clamping the wheel on the
unit.
—
Lift the pedal so as to clamp or unclamp the wheel.
—
Depress the pedal to actuate the brake, and lock
the chuck.

Ultrasonic detector
On the outer side of the rim the machine has an
ultrasound detector for the wheel width (
Fig. 4-18
).
The sonar has a tolerance of +/- 0.5’’.
Such tolerance does not jeopardise the accuracy of
the balancing procedure.
4.6 Laser Pointer
(if present)
Figure 4.-19
The machine uses the
Laser Pointer
to indicate the precise
point for fi tting the stick-on weights on the rim (
F
5.9).
Note
:
If the machine is set in Gauge arm mode as default, the
Laser Pointer mode can be activated by calling service.
