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 0.59 Mpa (5.9 bar), a
compressor with an air output over 80 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 an air hose as large and as short as possible to
assure continuous, efficient nailing operation. With an air
pressure of 0.49 Mpa(4.9bar), an air hose with an
internal diameter of over 8.5 mm and a length of less
than 20 m (6.6 ft.) is recommended when the interval
between each nailing is 0.5 seconds.
50 60
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.
Fig.2
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
after pneumatic tool oil is introduced.

FUNCTIONAL DESCRIPTION

CAUTION:
Always lock the trigger and disconnect the hose
•
before adjusting or checking function on the tool.
Nose adapter
When nailing workpieces with easily-marred surfaces,
use the nose adapter. It is factory installed at the rear of
the tool.
Fig.4
Attach the nose adapter to the contact arm. When not in
use, store the nose adapter at the rear of the tool to keep
it from being lost.

Adjusting depth of nailing

To adjust the depth of nailing, turn the adjuster so that the
arrow above the adjuster will point to the number
indicated on the adjuster. The depth of nailing is the
deepest when the arrow points to the number 1. It will
become shallower as the arrow points to higher number.
The depth can be changed in approx. 1.0 mm increments
per graduation. If nails cannot be driven deep enough
even when the arrow points to the number 1, increase
the air pressure. If nails are driven too deep even when
the arrow points to the number 9, decrease the air
pressure. Generally speaking, the tool service life will be
longer when the tool is used with lower air pressure and
the adjuster set to a lower number.

CAUTION:
Always lock the trigger and disconnect the hose
