Using an impact wrench contd.
16) Only install the tool when an easily accessible
and easily operable on/off switch is
incorporated in the air supply.
17) Take care that the tool exhaust air does not
cause problems or blow onto another person.
18) Never lay a tool down unless the working
attachment has stopped moving.
19) Always ensure that the forward/reverse switch
is in the desired position before starting
the tool.
20) Do not use sockets with excessive wear to the
input or output drives. Periodically check the
squae drive on the impact wrench. Make surer
the socket, extension bar, or other attachment
is securely fitted before operating tool.
21) When loosening fasteners first ensure that
there is sufficient clearance behind the tool to
avoid hand entrapment. The tool will move
away from the threaded joint as the nut/bolt is
loosened and rides up the thread, moving the
tool with it.
Safety rules for pneumatic tools
1) Inspect the air hose for cracks or other
problems. Replace the hose if worn.
2) Never point an air hose at another person.
3) Disconnect the tool when not in use, or before
performing service or changing accessories.
4) Use proper hoses and fittings. Never use
quick-change couplings attached to the tool.
Instead, add a hose and coupling between the
tool and the air supply.

The recommended hook-up is shown in figure A.
Pneumatic tools operate on a wide range of air
pressures. For maximum efficiency and longer
tool life, the pressure of the air supplied to these
tools must not exceed the rated PSI at the tool
when the tool is running. Using a higher than
rated pressure will cause faster wear and
drastically shorten the tool's life. A higher air
pressure can also cause an unsafe condition
and explosion.
The inside diameter of the hose should be
increased to compensate for unusually long air
hoses (over 25 feet). Minimum hose diameter
should be 3/8" I.D. and fittings should have the
same inside dimensions.
The use of air line lubricators and air line filters
is recommended to prevent water in the line that
can damage the tool. Drain the air tank daily.
Clean the air inlet filter screen on at least a weekly
schedule to remove accumulated dirt or other
matter that can restrict air flow.
The tool's air inlet used for connecting an air
supply has standard 1/4" NPT American thread.
