Specific Operating Instructions
1. If an automatic oiler is not used, add
a few drops of Pneumatic Tool Oil
inside the air inlet before every use.
2. Note: Air Die Grinder is designed to
be used with grinding attachments,
and sanding discs and other
attachments.
3. Use the two Wrenches (44) to loosen
the Collet (31) and Collet Nut (32) .
See Figure A below.
4. Insert 1/4” diameter shank of a
Grinding Accessory (not included)
fully into Collet Nut. Then, firmly
re-tighten Collet Nut to lock both the
Collet and Grinding Accessory in
place.
5. Connect air supply hose to Air Inlet
(1). Turn on air compressor and set
its regulator to the max. 90 PSI for
Die Grinder.
6. WARNING! Grip the Die Grinder
firmly with both hands.
7. Trip the Safety Lock (41) with your
finger. Slowly apply hand pressure to
the Trigger Lever (4) until the de-
sired speed is obtained.
8. NOTE: The Die Grinder always turns
the Accessory clockwise (reference:
while holding the tool as you would
when operating it). And always point
abrasive material away from you.
9. With a firm grip on the Die Grinder,
lightly apply Accessory to workpiece,
slowly and steadily moving tool to
right and left until achieving desired
appearance (finish) on workpiece.
10. If Air Die Grinder requires more
force to accomplish task, verify that
it receives sufficient, unobstructed
airflow (CFM) and increase pressure
(PSI) output of regulator up to
maximum air pressure rating of tool.
11. If the tool still does not have suf-
ficient force at maximum pressure
and sufficient airflow, then a larger
tool may be required.
12. CAUTION! TO PREVENT TOOL
AND ACCESSORY FAILURE,
RESULTING IN INJURY:
Do not exceed the tool’s
maximum air pressure rating.
13. Once work is completed, release
hand pressure on Trigger Lever. The
Safety Lock will automatically return
to its locked position to prevent
Trigger Lever from accidentally
being activated.
14. Turn off air compressor. Trip Safety
Lock with your finger and slowly
squeeze Trigger Lever to release
any remaining air pressure from Die
Grinder. Then disconnect air hose.
15. Remove Accessory from Die
Grinder. Store the tool in a clean
and dry location out of the reach of
children.
