Operation
The grinder must be properly
lubricated before operation. See “Lubrication”
section.
Figure 1
1. Remove two nuts and outer wheel flange
from spindle.
2. Install grinding wheel (not provided), and
reinstall outer wheel flange and two nuts.
Hold the 50mm wrench on inner wheel flange
to prevent spindle from turning, and use the
double end wrench to tighten the hex nuts.
3. Adjust wheel guard to appropriate position.
4. Remove protective cap from air inlet. 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 securely with both hands and
press throttle lever. The throttle lock may be
engaged to continue operation without
holding the lever.
7. Position grinding wheel against workpiece
with steady pressure.
8. Press in throttle lever and disengage throttle
lock to stop grinder.
User-maintenance
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.
Storage
Avoid storing the grinder in very humid locations
which promotes rusting of internal mechanisms.
Always oil the tool and disconnect air hose before
storage.
