Operation
The pneumatic sander must
be properly lubricated before operation. See
“Lubrication” section.
Figure 1
1.
Sanding disc (not provided) may be resin-
bonded or pressure sensitive adhesive
(PSA).
2. Install backing plate, sanding disc, and
flange nut. Tighten flange nut. If using PSA
disc, press firmly onto backing plate.
3.
Adjust speed using air regulator knob.
4.
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.
5. 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.
6.
Grip sander firmly, and place other hand over
top of housing. Gently press trigger.
7. For best results, keep sander moving in
overlapping motions while pressing it to
workpiece. Do not force the sander, allow the
tool to do the work.
8.
Release trigger to stop sander.
9.
Unscrew flange nut to remove sanding disc
and plate. If needed, insert end of holding
tool into hole for better leverage, while
turning flange nut with a flat object, such as
a screwdriver.
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.
