5. Connect a regulator valve, an in-line
shut off valve and a 1/4” NPT air hose
(all sold separately) to the Quick
Coupler (76). The air hose must be
long enough to reach the work area
with enough extra length to allow free
movement while working.
Note: 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.
Depending on the tool which you will 6.
be using with this compressor, you
may need to incorporate additional
components, such as an in-line oiler,
a lter, or a dryer (all sold separately).
Consult your air tool’s manual for
needed accessories.
