6.
Adjust the Air Regulator (13) to the
desired torque setting. NOTE: The
actual torque delivered at each of the
several torque settings will depend
on the air pressure supplied to the
tool. We suggest that you test the
actual torque by tightening a nut or
bolt on a test piece using each
setting, then observing the resultant
torque by using a mechanical torque wrench (not supplied).
7.
If installing a nut or bolt, set it as tight as possible by hand.
8.
Place the impact socket (not included) over the fastener. Grip the Air Ratchet
Wrench tightly with both hands, and squeeze the trigger (8). The tool will
operate and tighten the fastener.
9.
When the fastener is tightened, release the Trigger (8), and remove the tool
from the fastener.
10. If possible, check the actual torque applied to the fastener with a mechanical
torque wrench (not supplied). If additional torque is required beyond what is
delivered by using air pressure, the fastener may be further tightened using
this tool in the manner of a standard ratchet wrench.
11. If removing a fastener, rotate the Reverse Button (38) counterclockwise,
assuming that the fastener is a standard right-hand thread. Always check to
be sure of the thread direction of any fastener before attempting to install or
remove it. If the fastener is a left-hand thread, turn the Reverse Button (38) to
the right for removal.
12. Place an appropriate impact socket (not included) over the fastener. Holding
the Air Ratchet Wrench with both hands, squeeze the Trigger (8). The fastener
should come off.
WARNING: If the fastener will not come off, first check to be sure of the
direction of the thread. If you have the thread direction correct and the
fastener will not come off, DO NOT INCREASE THE AIR PRESSURE to the
tool beyond 90 psi. This may damage the tool. You may have to use pen-
etrating oil, heat, or a mechanical wrench to remove the fastener.
13. When you are done using this tool, turn off the air compressor, and disconnect
the air hose. Put the Air Ratchet Wrench away in its proper storage place.
Note: Never over-
tighten the nut or bolt;
damage may result
from over-tightening.
