Air Connection; Operation - Central Pneumatic 53176 Assembly And Operating Instructions Manual

Air Connection

1. Remove the Screen from the Inlet (both included in part 42). You will need an air hose
fitting (sold separately) before you can connect your Impact Wrench to an air compressor.
2. Attach the air hose fitting to the Inlet and tighten with a wrench.
3. Attach a quick-disconnect coupler (sold separately) to the air hose fitting if desired. This
is a useful accessory as it allows quick-coupling action when using a variety of tools with the
same air compressor.
4. The Impact Wrench is ready for use.

Operation

Frequent but not excessive, lubrication is required for best performance. Oil added through
the airline connection will lubricate internal parts. An automatic airline oiler is recommended but
oil may be added manually before every operation or after about 1 hour of continuous use. Only
a few drops of oil at a time are necessary. Too much oil will collect inside the tool and be blown out
during the exhaust cycle. ONLY USE PNEUMATIC TOOL OIL. Do not use detergent oil or
additives as these lubricants will cause accelerated wear to the seals in the tool.
Dirt and water in the air supply are major causes of pneumatic tool wear. Use a filter/oiler for
better performance and longer life. The filter must have adequate flow capacity for the specific
application. Consult the manufacturer's instructions for proper maintenance of your filter.
The connector on the tool must not hold pressure when the air supply is disconnected. If the
wrong fitting is used, the tool can remain charged with air after being disconnected.
Your Impact Wrench features an air Regulator (37), allowing you to vary the amount of torque
exerted on the nut or bolt you are working on. Setting "1" is the lowest setting, and is recom-
mended for smaller nuts and bolts. Setting "4" is the highest setting and provides the most torque
and speed.
Loosening
1. Attach the correct size socket to the Anvil (8).
2. Set the compressor's pressure regulator to 90 PSI. Do not set the compressor's outlet
regulator above 90 PSI.
3. Connect the Impact Wrench to the air compressor's hose. If leaking is detected, discon-
nect the air hose and repair before use.
4. Place the socket over the nut to loosen.
5. Grip the Impact Wrench firmly. Press the Reverse Valve (44) in from the area above the
Trigger (29) so that the Reverse Valve protrudes out the back of the Housing. Press the Trigger to
start the Impact Wrench.
Caution: Make sure the nut or bolt can withstand the Impact Wrench's working torque.
