ADJUSTMENTS

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.
