Nailing frequency (times/min.)

The air compressor must comply with the requirements
of EN60335-2-34.
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 0.59 MPa (5.9 bar), a compressor
with an air output over 3 CFM (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.
Selecting air hose
004294
Use an air hose as large a diameter and as short as
possible to assure continuous, efficient nailing
operation. With an air pressure of 0.49 MPa (4.9
bar), an air hose with an internal diameter of over
8.5 mm (5/16") and a length of less than 20 m (6.6
40
50
times

minute

/minute) is
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 (10.3 bar) or 150 percent of the 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
proper lubrication, the tool must be fired a couple of times
at
a
after pneumatic tool oil is introduced.
