TOOL INSTALLATION INSTRUCTIONS AND US€
Selecting compressor
The air compressor must comply with the require-
ments of ANSI 819.3
-
1981.
Select a compressor that has ample pressure and air
output to assure cost-efficient operation. The graph
shows the relation between nailing frequency, applica-
ble pressure and compressor air output. Thus, for
example, if nailing takes place at a rate of approxi-
mately 40 times per minute at a compression of 0.49
MPa (70 PSIG). a compressor with an air output over
2 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.
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 0.49 MPa (70 PSIG), an air hose with
an internal diameter of over 6.5 mm (1/4") 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 1.06 MPa (150 PSIG) or 150 percent of the
maximum pressure produced in the system whichever
is higher.

I
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
T o 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 50 nails.
When an air set is not used, oil the tool with pneu-
matic tool oil by placing
2
(two) or 3 (three) drops into
the air fitting. This should be done before and after
use. For proper lubrication, the tool must be fired a
couple of times after pneumatic tool oil is introduced.
