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
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, applica-
ble pressure and compressor air output.
Thus, for example, if nailing takes place at a rate of
approximately 30 times per minute at a compression of
100 PSIG (0.69 MPa), a compressor with an air output
over 80 liters/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 70 PSIG (0.49 MPa), an air hose with an
internal diameter of over 6.5 mm and a length of less
than 20 m is recommended when the interval between
each nailing is 0.5 seconds. Air supply hoses shall have
a minimum working pressure rating of 150 PSIG (1.03
MPa) or 150 percent of the maximum pressure pro-
duced 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.
