TOOL INSTALLATION INSTRUCTIONS AND USE
Selecting compressor
The air compressor must comply with the requirements of
Select a compressor that has ample pressure and air output
to
assure cost-efficient operation. The graph shows the
relation between nailing frequency, applicable pressure and
compressor air output. Thus, for example,
if
nailing takes
place at a rate of approximately
40
times per minute at a
compression of
6
kgf/cm2G (85 PSIG), a compressor with
an air output over 3 ft3/minute is required. Pressure
regulators must be used to limit air pressure to the rated
pressure of the tool where air supply pressure exceeds the
tool’s rated pressure. Failure to do
so
may result in serious
injury to tool operator or persons in the vicinity.
ANSI B19.3
-
1981.
Selecting air hose
Use an air hose as large and as short as possible to assure
continuous, efficient nailing operation. With an air pressure
of
5 kgf/cm2G (70 PSIG), an air hose with an internal
diameter of over
8.5
mm
(5/16”)
and a length of less than
20
m
(6.6
ft.) is recommended when the interval between
each nailing is
0.5
seconds. Air supply hoses shall have a
minimum working pressure rating of 10.7 kgf/cm2G (150
PSIG) or
150
percent of the maximum pressure produced
in the system whichever is higher.

(timedmin.)
CAUTION:
Low air output of the compressor, or a long or smaller diameter air hose in relation to the nailing frequency
may cause a decrease in the driving capability of the tool.
Lubrication
To insure maximum performance, install an air set (oiler,
regulator, air filter) as close as possible to the tool. Adjust
the oiler
so
that one drop of oil will be provided for every
30 nails.
When
n ir et is not used,
oil
the tool with pneumatic tool
oil by placing
2
(two) or 3 (three) drops into the air fitting.
This should be done before and after use. For proper lubri-
cation, the tool must be fired a couple of times after pneu-
matic tool oil is introduced.
