4.5 Main shaft lock
Fig. 4-16
Pedal of main shaft lock
The main shaft is locked when the pedal is depressed.
This facilitates tightening or untightening of the
clamping nut and retains the wheel in the correction
position for correct fi tting of the balance weights.
Note
:
This lock is designed only to facilitate orientation
of the wheel and must not be used for braking the
main shaft.
4.6 Gauge arms

2
Position to locate the adhesive weight both for
identifi cation of subsequent fi tting position and
for actual fi tting of the balance weight.
3 Adhesive weight kept in weight positioner.
4 Gauge head to identify rim dimensions on a
variety of rim profi les.
4.7 Ultrasonic detector
(S-Version Maschine)
On the outer side of the rim the machine has an
ultrasound detector for the wheel width (outside of
rim) (
Fig. 4-17b
).
The sonar resolution is 0,5 inch.
That tollerance 0,5 inch doesn’t affect the precision
of the balancing.
