Initial Cut
The purpose of the initial cut is to remove old finish and gross imperfections on the floor surface. The sanding equipment should be adjusted to
heavy sanding pressure setting and a coarse abrasive should be used. If the surface is severely damaged by deep scratches, pre-existing dwell
marks, uneven planks, etc., it may be necessary to sand across or diagonally to the grain to restore evenness to the surface. If these conditions are
not present, the initial cut should be done in the direction of the grain.
If glazing, loading, or burning takes place immediately into an initial cut, select a coarser abrasive. If this should occur during an initial cut, the
abrasive has dulled and must be replaced.
Final Cuts
The purpose of a finishing cut is to remove the scratches produced during the initial cut. Use a fine (60 - 80 grit) grain abrasive and a reduced
sanding pressure setting.
If the surface remains rough after a finishing cut, it may be necessary to use an even finer grain of abrasive (80 - 100 grit). Care should be taken in
selecting the grit size of the abrasive. A very fine grain will close the pores on a wood floor making admission of a stain difficult.
If glazing or burning should occur immediately into a finishing cut, reduce the sanding pressure. If it should occur during a finishing cut, the abrasive
has dulled and must be replaced.

Sanding Pressure
To adjust the sanding pressure follow this procedure:
1. Screw the sanding pressure knob down to increase the sanding pressure when making the roughing in cut.
2. Screw the sanding pressure knob up to decrease the sanding pressure when making the finishing cut.
Drum Rates
The machine can be operated at two rates. To change the speed of the drum, follow this procedure:
1. Remove the belt cover.
2. Remove the fan belt.
3. Loosen the motor bolt.
4. Slide the motor forward.
5. For high drum rates, install drive belt in larger diameter of the grooves available on the motor pulley and in the smaller diameter of the two
grooves available on the drum pulley. For lower rates, install drive belt in smaller diameter of the grooves available on the motor pulley and in
the larger diameter of the two grooves available on the drum pulley.
6. Tighten belt and secure motor to chassis.
7. Install the fan belt.
8. Install the belt guard.

Sander Adjustment Procedures
Electrocution could occur if maintenance and repairs are
performed on a unit that is not properly
disconnected from the power source. Disconnect the power
supply before attempting any maintenance or service.
Moving parts of this machine can cause serious injury and/or
damage. Keep hands, feet and loose clothing away from all moving parts of the sander.
