H7949/H7950/H7951 Nailer
-6-
Compressed Air
System
The Model H7949/H7950/H7951 is
designed to be operated at 70–110 PSI
using clean, dry, regulated, compressed
air. DO NOT exceed 120 PSI.
Before using your new nailer, set the air
pressure on your regulator to the mini-
mum PSI for your model.
An in-line filter/lubricator/regulator unit,
depicted in Figure 2, can be installed and
should be located as close to the nailer
as possible.
This filter/lubricator/regulator unit will pro-
tect your tool from damaging water build-
up, allow you to adjust and maintain con-
stant air pressure to your tool, and save
you the inconvenience of manually lubri-
cating your tool every time you use it.
