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
2
6.0 kgf/cm G (85 PSIG), a compressor with an air output
3
over 3 ft /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 5.0 kgf/cm
internal diameter of over 8.5 mm (5/16") and a length of
less than 20 m (6.6 ft.) is recommended when the inter-
val between each nailing is 0.5 seconds. Air supply
hoses shall have a minimum working pressure rating of
2
10.7 kgf/cm G (150 PSIG) or 150 percent of the maxi-
mum pressure 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 fit-
ting. 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.
