Storage
Avoid storing the die grinder in very humid
locations which promotes rusting of internal
grinding
mechanisms. Always oil the tool and disconnect
air hose before storage.
Blow out air line to remove any dirt or
moisture, then connect air supply hose to
tool. Set air pressure to 90psi.
Make sure grinder is off (air regulator turned
all the way counterclockwise). Turn on air.
Hold die grinder firmly and rotate air
regulator clockwise to turn on and adjust
speed. A directional graphic is printed next to
the regulator.
Wait for grinder to reach operating speed,
then gently move it into contact with
workpiece. Do not force.
When finished, turn air regulator to off.
Disconnect air hose from tool.
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.
Re-connect air. Run die grinder at low
throttle without load for a few seconds to
distribute the oil throughout tool.
When
finished
operating

dry cloth. Place 4 or 5 drops of air tool oil into
