OPERATING INSTRUCTIONS
To operate the machine, follow this procedure:
1. Set any exposed nails with a hammer and punch to
avoid encounter with sanding pad.
2. Connect the machine to an appropriately grounded and
fused circuit (power supply).
3. Tilt the machine back so that the sanding pad does not
contact the floor. Select cutting speed. Use high
speed for fast stock removal. Use low speed for finish
cuts and custom work. See
figure 4 (A).
4. Depress and release the start/stop push button to start
the machine. See figure 4 (B).
5. Gradually lower sanding pad to the floor. Make sure
the machine is in motion while the sanding pad is
engaged with the floor. Broad circular motions can be
used as you sand along the length of the floor or you
may use a combination of forward and sideway
motions. In time you will develop your own technique
to optimize coverage and dust control. It is advisable
to not add effort to the pad as this may lead to
"nosing" or "tipping" which produces grooves or lines
on the floor.

SANDING CUTS AND SANDPAPER
Initial Cut
The purpose of the initial cut is to remove old finish and gross imperfections on the floor surface. 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.
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, increase pace. If it should occur during a
finishing cut, the abrasive has dulled and must be replaced.
