Symbols
The followings show the symbols used for tool.
Read and understand tool labels and man-
ual. Failure to follow warnings could result
in death or serious injury.
Operators and others in work area must
wear safety glasses with side shields.
Keep fingers away from trigger when
not driving fasteners to avoid accidental
discharge.

Nailing frequency (times/min)
The air compressor must comply with the requirements
of ANSI B19.3.
• 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 0.59 MPa (85 PSIG), a compres-
sor with an air output over 3 ft
Pressure regulators must be used to limit air pres-
sure 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.

/minute is required.
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 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 1.03 MPa
(150 PSIG) or 150 percent of the maximum pres-
sure produced in the system whichever is higher.
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 an air set 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 lubrication, the tool must be fired a couple of
times after pneumatic tool oil is introduced.
