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.
Note
:
On wheel balancers equipped with the quick–acting
Power Clamp
system: The pedal also controls
the
Power Clamp
, for clamping the wheel on the
balancer.

the balancing procedure.
