Warning: The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be under-
stood by the operator that common sense and caution are factors which cannot be
built into this product, but must be supplied by the operator.
1. You will need to prepare a 1/4” air connector (sold separately) to connect to the air inlet on
the Sander. First, wrap the 1/4” air connector (not included) with pipe thread seal tape before
threading into Air Inlet (#11). Connect the 3/8” I.D. Air Source Hose (not included) to the
Sander.
Note: If you are not using an automatic oiler system, before operation, add a few drops of
Pneumatic Tool Oil to the airline connection. Add a few drops more after each hour of
continual use.
2. Set the air pressure on your compressor to 90 PSI. Do not exceed the recommended air
pressure of 100 PSI.
3. Check the air connection for leaks. Then, disconnect the Sander from the air hose and
turn off the air compressor.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities, contain chemicals known [to the State of California] to
cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
- Lead from lead-based paints
- Crystalline silica from bricks and cement or other masonry products
- Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do this type of
work. To reduce your exposure to these chemicals: work in a well ventilated area,
and work with approved safety equipment, such as those dust masks that are spe-
cially designed to filter out microscopic particles.
