AIR CONNECTION
Note: Air Compressor is not supplied.
1. Acquire a Union fitting (not supplied) and screw into the Air Inlet fitting.
Tighten with the wrench.
2. Attach a quick-coupler (not supplied) to the Union fitting if desired. This
allows quick exchange of the Air Hose to other air tools.
3. Connect the Air Hose to the Air Inlet Coupling.
Warning: Follow all air compressor warnings before using tool.
This air tool requires lubrication during operation. For best results, it is recom-
mended to have an oiler and water filter in line with the air supply as shown on
Page 5. This will extend the life of the tool.

Warning: Before installing the attachment, make sure Grinder is not
attached to the air supply and make sure no built up air pressure
remains in the Air Die Grinder.

Retainer [24] while removing the Collet Nut (27).

4. Reassemble the Collet and Collet Nut. Tighten with both Wrenches.
5. Set the Air Compressor’s pressure regulator to 90 PSI.
6. Connect the Die Grinder to the Air Compressor’s hose.
7. Secure the stock you will be grinding. Warning: Do not hold the stock
with your hand.
8. Wear safety glasses or a full face mask.
9. Grip the Die Grinder firmly with your hand, then squeeze the Safety
Throttle Lever (13) to turn it on. The speed of the Die Grinder depends on
how far down you press the Lever.

excessive force to press the attachment into the stock surface that is
being ground. If the Die Grinder stalls while being operated, immediately
release the Lever and pull the Die Grinder away from the surface.
