Operation (continued)

Loosening

Note: Set the Forward/Reverse Valve (17) so that the anvil turns counterclockwise (reverse).

12.

Place the socket (not included) over the nut you wish to loosen.

13.

Grip the Impact Wrench firmly with two hands and gently squeeze the Trigger (13).

Note: If the Impact Wrench cannot loosen the nut, do not raise the air pressure on the

compressor over 90 PSI.  Do not attempt to loosen the nut with the Impact Wrench.
Use other appropriate methods and tools to loosen the nut.

14.

When the nut is loosened, release the Trigger (13).  Turn off the air compressor and
disconnect the hose.

15.

If needed, remove the nut from the socket.

Maintenance

1.

Make sure your Impact Wrench is disconnected from the air hose before attempting
any maintenance.

2.

Wipe the Impact Wrench down with a lint-free cloth after each use.

3.

Make sure the Anvil (38) is clear of dirt or debris.  If possible, spray it with compressed
air before each use.

4.

If you do not use an inline oiler/filter system, lubricate the tool daily by holding it so that
the Air Inlet (10B) is facing up. Squeeze the Trigger (13), and place one or two drops of
oil into the Air Inlet (10B).  Squeezing the Trigger (13) allows the oil to circulate in the
motor.

5.

Repairs to this tool should be performed only by a qualified technician.
