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
compression of 6.0 kgf/cm
compressor with an air output over 3 ft
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.

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
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/cm
maximum 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
004295
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
at a
proper lubrication, the tool must be fired a couple of times
after pneumatic tool oil is introduced.
