Operation
The angle polisher must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1.
Install dead handle into either side of tool.
2.
Push spindle lock button and hold.
3.
Thread backing disc clockwise onto the
spindle.
4.
Install disc nut and tighten with spanner.
5.
Install polishing pad (not provided).
6.
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.
7.
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.
8.
Grip handle firmly, and place other hand on
dead handle. Push throttle lock to release
throttle lever.
9.
Gently press throttle lever. Pressure against
throttle lever determines rotation speed of
tool.
10. For best results, keep polisher moving in
wide, overlapping motions while holding it
against work surface. Do not force the
polisher, allow the tool to do the work.
11. Release throttle lever to stop polisher.
12. To remove backing disc, engage spindle lock
and unscrew disc nut with pin wrench.
Maintenance
Lubrication
The polisher 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 polisher at low throttle
without load for a few seconds to distribute
the oil throughout tool.
