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. Connect a regulator valve, an in-line shut
off valve and 1/4” NPT air hose (all sold
separately) to the Quick Coupler. Use
thread tape for all threaded connections.
The air hose must be long enough to
reach the work area with enough extra
length to allow free movement while
working. 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. See pages 8
and 9 for Air Tool Setup procedures.
Note: If an automatic oiler system is not
used, add a few drops of Pneumatic
Tool Oil into the airline connection before
operation. Add a few more drops after
each hour of continual use.
