General Operating Instructions
1. If an automatic oiler is not used, add a few
drops of Pneumatic Tool Oil to the airline
connection before use. Add a few drops
more after each hour of continual use.
2. Wipe the work surface clean of all dirt and
debris, especially that of previous courser
sanding sessions, which will scratch the
surface of a finer grit sanding session.
3. Attach the desired grit sanding disc (sold
separately) onto the Backing Pad.
4. Attach the air supply.
5. Grip the Handle and depress the Trigger
to start the tool
. The speed of the
Sander may be varied by turning the
Air Regulator. Allow the tool to reach
the intended speed before sanding.
cAUTION! Do not allow free, no-load
rotating at high speed to avoid possible
injury or damage to the tool.
6. Keep heavy pressure off of the
Sander when operating. Allow the
sanding disc to do the work.
7. Move the Sander in a uniform pattern up and
down or side to side to ensure even sanding.
Note: If the Sander creates swirls when
it contacts the workpiece, disconnect the
air supply and verify that the Spindle Lock
is not engaging with the Drive Spindle.
8. Periodically, stop the Sander and check
for possible disc wear. Replace used or
worn sanding discs when necessary.
9. If the tool requires more force to accomplish
the task, verify that the tool receives
sufficient, unobstructed airflow (CFM)
and increase the pressure (PSI) output
of the regulator up to the maximum
air pressure rating of this tool.
cAUTION! TO pREVENT INJURy FROM
TOOL OR AccESSORy FAILURE:
Do not exceed the tool’s
maximum air pressure rating.
If the tool still does not have sufficient force
at maximum pressure and sufficient airflow,
then a larger tool may be required.
10. To prevent accidents, after use, release
the Trigger, detach the air supply and then
safely discharge any residual air pressure
in the tool. Clean external surfaces of the
tool with a clean, dry cloth. Then store the
tool indoors out of children’s reach.
