The red emergency disconnect button and power must be in the OFF postion before intallation and
the pad driver assembly in the RAISED position. Remove center cup locking device by gripping on
outer edges and turning clockwise.
After removing used pad, place new pad on pad driver assembly using outer flange of pad driver to
center the pad. Push centering locking cup through the pad and into the pad driver assembly. The
ratchet teeth on the center cup will engage into the pad driver assembly and should be pushed in as
far as possible. If further tightening is needed, rotate the center-locking cup counter-clockwise.

The pad pressure adjust knob is located on the top of the control console. Counter-clockwise rotation
increases pad pressure, the opposite rotation decreases. Different floors, conditions, and pads
produce carying pad load conditions. Ideal burnishing conditions are maintained while the operating
range meter remains in the Green Zone. If the meter reads in the Red Zone decrease the pad
pressure. When the machine is operated in the Red Zone for a long period of time motor overload
will occur and the 70-amp circuit breaker for the motor will trip. If the motor circuit trips:
1. Check pad condition.
2. Decrease pad pressure.
3. Reset circuit breaker.
