Nailing frequency
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 30 times per minute at a compression of
0.69 MPa (6.9 bar), a compressor with an air output over
80 L/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 (4.9 bar), an air hose with an inter-
nal diameter of over 6.5 mm and a length of less than
20 m is recommended when the interval between each
nailing is 0.5 seconds. Air supply hoses shall have a min-
imum 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
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 fit-
ting. 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. (Fig. 3)

FUNCTIONAL DESCRIPTION

CAUTION:
• Always disconnect the air hose before adjusting or
checking function on the tool.
Adjusting depth of nailing (Fig. 4)
To adjust the depth of nailing, turn the adjuster. The
depth of nailing is the deepest when the adjuster is
turned fully in the A direction shown in the figure. It will
become shallower as the adjuster is turned in the B
direction. If nails cannot be driven deep enough even
when the adjuster is turned fully in the A direction,
increase the air pressure. If nails are driven too deep
even when the adjuster is turned fully in the B direction,
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 depth of nail
driving.
CAUTION:
• Always disconnect the hose before adjusting the depth
of nailing.
Use the nose adapter (Fig. 5)
CAUTION:
• Always disconnect the hose before installing or remov-
ing the nose adapter.
If you like to protect the surface of workpiece, attach the
nose adapter of contact element.
When nailing workpieces with easily-marred surfaces,
use the nose adapter. To attach the nose adapter to the
contact element, press it onto the contact element until
the protrusion in three places inside the nose adapter fit
in three holes in the contact element.
ASSEMBLY
CAUTION:
• Always disconnect the air hose before carrying out any
work on the tool.
Loading nailer
Select nails suitable for your work. Depress the latch
lever and open the door. And then open the magazine
cap. (Fig. 6)
Lift and turn the coil support plate so that the arrow with
nail size indicated on the coil support plate will point to
the corresponding graduation increment marked on the
magazine. If the tool is operated with the coil support
plate set to the wrong step, poor nail feed or malfunction
of the tool may result. (Fig. 7)
Place the nail coil over the coil support plate. Uncoil
enough nails to reach the feed claw. Place the first nail in
the driver channel and the second nail in the feed claw.
Place other uncoiled nails on feeder body. Close the
magazine cap after checking to see that the nail coil is
set properly in the magazine. (Fig. 8)
Connecting air hose (Fig. 9)
Slip the air socket of the air hose onto the air fitting on
the nailer. Be sure that the air socket locks firmly into
position when installed onto the air fitting. A hose cou-
pling must be installed on or near the tool in such a way
that the pressure reservoir will discharge at the time the
air supply coupling is disconnected.
