Main shaft lock
Fig. 4-7 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 “p” equipped with the quick–
acting

system: The pedal also
controls the

, for clamping the wheel
on the balancer.
•
Lift the pedal so as to clamp or unclamp the wheel.
•
Depress the pedal to actuate the main shaft lock,
thus locating the main shaft.
