The air compressor must comply with the requirements
driven 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 pin-driving frequency,
applicable pressure and compressor air output.
and Thus, for example, if pin driving takes place at a rate of
approximately 15 times per minute at a compression of
250 PSIG (1.76 Mpa), a compressor with an air output

Makita over 2.5 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 a high pressure resistant air hose.
Use an air hose as large and as short as possible to
assure continuous, efficient pin-driving operation.
CAUTION:
Low air output of the compressor, or a long or

smaller diameter air hose in relation to the pin-
driving 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.
