Air Supply...
Tools of this class operate on a wide range of air pressures. It is
recommended that air pressure of these tools measure 90 PSI at the
tool while running free. Higher pressure and unclean air will
shorten the tool’s life because of faster wear and may create a
hazardous condition.
Water in the air line will cause damage to the tool. Drain the air
tank daily. Clean the air inlet filter screen on at least a weekly
schedule. The recommended hookup procedure can be viewed in
Figure 1.
The air inlet (B) Figure 2, used for connecting air supply, has
standard 1/4" NPT American Thread.
Line pressure should be increased to compensate for unusually long
air hoses (over 25 feet). Minimum hose diameter should be 1/4"
I.D. and fittings should have the same inside dimensions.

Lubrication...
Lubricate the tool daily with a good grade of air tool oil. If no air
line oiler is used, run a teaspoon of oil through the tool. The oil can
be squirted into the tool air inlet (B) Figure 2, or into the hose at the
nearest connection to the air supply, then run the tool. A rust
inhibitive oil is acceptable for air tools.
WARNING: After an air tool has been lubricated, oil will discharge
through the exhaust port during the first few seconds of operation.
The exhaust port must be covered with a towel before applying air
pressure to prevent serious injury.
Troubleshooting...
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air line,
moisture or restrictions in air pipes or the use of hose connections of
improper size or poor condition may reduce air supply. Grit or gum
deposits in the tool may cut power and may be corrected by
cleaning the air strainer and flushing out the tool with gum solvent
oil or an equal mixture of SAE #10 oil and kerosene. If outside
conditions are in order, disconnect tool from hose, and take tool to
your nearest authorized service center.
Operation...
The air regulator knob can be used as an air throttle and can be
used for setting positive speed control. The air inlet used for
connecting air supply has standard 1/4" NPT thread.
Let the sander do the work. The normal weight of the machine is
sufficient for efficient sanding. Do not put additional pressure on the
machine. This will only slow down the speed of the pad, reduce
sanding efficiency and put an additional burden on the motor. Start
the sander off the work, set it down on the work evenly and move it
slowly back and forth in wide, overlapping areas. When finished
sanding, lift it off the work before stopping the motor.
