Operation
The angle grinder must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1. Install dead handle into threaded hole on
either side of grinder.
2.
Press spindle lock and rotate disc pad until
engaged.
3. Unscrew disc nut from spindle and install
grinding wheel. Reinstall disc nut securely.
4.
Remove protective cap from air inlet (Figure
2). 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. Hold grinder with a light but secure grip.
Push throttle lock knob to release throttle
lever.
7. Gently press throttle lever. Rotation is
clockwise as viewed from above tool.
Pressure against throttle lever determines
rotation speed.
8.
Place grinding wheel against workpiece with
a steady pressure. Do not use excessive
pressure – allow the tool to do the work.
9.
Release throttle lever to stop grinder.
To reposition disc guard, loosen the two socket
head cap screws with provided wrench and rotate
guard to desired position. Re-tighten screws.
Maintenance
Lubrication
The grinder 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 grinder at low throttle
without load for a few seconds to distribute
the oil throughout tool.
4.
When finished operating grinder, 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.
