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

of the wheel and must not be used for braking the
main shaft.
The pedal also controls the
Power Clamp
, 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.
By changing the mode of operation it is possible to
reverse the direction of actuation of the pedal.
