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 50 times per minute at a compression of
1.77 MPa (17.7 bar), a compressor with an air output
over 70 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
Fig.1
Use a high pressure resistant air hose.
Use an air hose as large and as short as possible to
assure continuous, efficient nailing operation.
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
Before and after use, oil the tool with pneumatic tool oil
by placing two or three drops into the air fitting. For
proper lubrication, the tool must be fired a couple of
times after pneumatic tool oil is introduced.
