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 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.
Depress the pedal to actuate the main shaft lock,
thus locating the main shaft.
