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
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.
