Setup and Assembly
Any missing parts or damage should be reported
immediately to your JET
®
distributor. Do not use a
damaged tool. Read this instruction manual
thoroughly for operation, maintenance and safety
instructions.

Operation
The pneumatic sander must
be properly lubricated before operation. See
“Lubrication” section.
Figure 1
1. Raise paper clamp by pushing on tab, and
insert end of sanding paper (not included).
Repeat for opposite end. Sandpaper must fit
snug against sanding pad.
2. Adjust speed using air regulator knob.
3. Remove protective cap from air inlet (Figure
1). If an in-line oiler is not being used, add 4
or 5 drops of air tool oil (not included) into the
air inlet.
4. Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90 psi.
IMPORTANT: Connecting a quick-change
coupling directly to the tool is not
recommended, as vibration may cause the
connection to fail. Instead, add a leader hose
and install any quick-change couplings
farther down the line.
5. Place sander on workpiece, and press down
on operating lever with palm while grasping
sander with your fingers.
6. Release operating lever to stop.
Maintenance
Lubrication
The sander should be lubricated daily (or before
each use) with air tool oil through the air inlet.
During continual operation, it should be re-oiled
every 1 to 2 hours. This can be done with an in-
line oiler, or manually. If done manually, proceed
as follows:
1. Disconnect air hose from tool.
2. Place 4 or 5 drops of air tool oil into air inlet.
NOTE: Air tool oil not provided; it is available
at most major hardware and tool stores. SAE
#10 oil or sewing machine oil may be used
as a substitute. Do not use detergent oil.
3. Re-connect air. Run sander at low throttle
without load for a few seconds to distribute
the oil throughout tool.
4. When finished operating sander, disconnect
air hose. Wipe off housing with a dry cloth.
Place 4 or 5 drops of air tool oil into air inlet;
re-connect air and run tool for a few seconds
to distribute the oil. Disconnect air.
Storage
Avoid storing the sander in very humid locations
which promotes rusting of internal mechanisms.
Always oil the tool and disconnect air hose before
storage.
Air system requirements
1. Use proper air hose size (refer to tool
specifications). The hose should be just long
enough to serve the working area. Excessive
hose length will cause pressure drop.
2. Make sure air compressor supplies clean,
dry air at correct CFM for the tool.
3. Set air pressure to 90 psi.
