Air Supply
TO PREVENT
EXPLOSION:
Use only clean, dry, regulated,
compressed air to power this
tool. Do not use oxygen,
carbon dioxide, combustible
gases, or any other bottled
gas as a power source for this
tool.
1. Incorporate a lter, regulator with
pressure gauge, oiler, in-line shutoff
valve, and quick coupler for best
service, as shown in the air tool setup
examples at the end of this section.
An in-line shutoff ball valve is an
important safety device because it
controls the air supply even if the
air hose is ruptured. The shutoff
valve should be a ball valve
because it can be closed quickly.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil to the airline connection
