Operation
The die grinder must be
properly lubricated before operation. See
“Lubrication” section.
Figure 1
1. 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.
2. Place the 8mm wrench on the rotor end
(Figure 1). Keep wrench stationary. Place
6mm wrench on collet flats and turn
counterclockwise to loosen collet.
3. Fully insert 1/8-in. shaft of grinding
attachment (not included) into collet, and
retighten collet securely with wrenches.
4. Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90psi.
5. Make sure grinder is off (air regulator turned
all the way counterclockwise). Turn on air.
6. Hold die grinder firmly and rotate air
regulator clockwise to turn on and adjust
speed. A directional graphic is printed next to
the regulator.
7. Wait for grinder to reach operating speed,
then gently move it into contact with
workpiece. Do not force.
8. When finished, turn air regulator to off.
Maintenance
Lubrication
The die 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 die grinder at low
throttle without load for a few seconds to
distribute the oil throughout tool.
4. When finished operating die 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 die grinder in very humid
locations which promotes rusting of internal
mechanisms. Always oil the tool and disconnect
air hose before storage.
