Make sure the compressor model you use has
sufficient cubic feet per minute (CFM) output for
the air tool you plan to connect. Most air tools will
have an air requirement stated in terms of a spe-
cific CFM at a specific pressure (PSI). Consult the
chart below to determine the output of your com-
pressor model.

The compressor should put out a higher CFM
than the tool requires. If connecting multiple tools
which will be used simultaneously, then the CFM
for each tool should be added together and com-
pared to the compressor output value.
Consideration should also be given to the type of
usage. A nailer or staple gun uses air in short
bursts and it is easier for the compressor to main-
tain pressure. A paint sprayer or grinder tends to
use a more continuous stream of air as these
tools are run for longer time periods. It is always
better to oversize a compressor to allow for vari-
ation in the type of usage and the number of tools
to be powered. Air tools being operated with
insufficient air volume will not perform their func-
tion satisfactorily.
Connect the tool using a good quality air line with
an adequate length to reach from the compressor
to the point of use. Quick-connect couplers are a
good option for fast and sure connection of tools
and air hoses. Make certain the air hose will not
be placed in a position where it can become con-
stricted or cut by a sharp object. Having a hose
run over by heavy vehicles may not cause an
immediate leak, but it will shorten the life of the
hose.
The air control valve lever is located just next to
the On/Off switch near the air outlet fitting. When
the lever is turned so it is in line with the fitting,
the valve is OPEN. When it is at a 90˚ position
relative to the fitting, the valve is CLOSED. (
See
Figure 5).
The air outlet supplied is a brass barb fitting
over which an air hose can be slipped. This
will be suitable for low pressure uses. If you
will be operating at higher pressure, or run-
ning air tools, you should replace this fitting
with a quick connect coupler which you can
find at your local hardware store.

There is also a pressure release valve which can
be used when decompression of the storage tank
is needed quickly and efficiently. Pull the metal
ring to release the pressure.
