• 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 60 times per minute at a compression of
0.69 MPa (6.9 bar), a compressor with an air output
over 60 L/min 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. 2)
• 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
internal diameter of over 6.5 mm (1/4") and a length of
less than 20 m (6.6 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 (Fig. 3 & 4)
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
50 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 after pneumatic tool oil is introduced.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always disconnect the hose before adjusting or
checking function on the tool.

Adjusting depth of nailing (Fig. 5)
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.
Hook (Fig. 6)
CAUTION:
• Always disconnect the hose from the tool.
• Never hook the tool at high location or on potentially
unstable surface.
The hook is convenient for hanging the tool temporarily.
ASSEMBLY
CAUTION:
• Always disconnect the hose before carrying out any
work on the tool.
• Load the same kind, size and uniform length of nails
when loading nails in the magazine.
Loading nailer
Press the lever and open the sliding door of the magazine
by pulling it toward yourself with the lever pressed.
(Fig. 7)
Align the tip of nails with the grooves at the bottom of the
magazine and push the whole part of nails toward the
firing opening. (Fig. 8)
Close the sliding door.
Nose adapter (Fig. 9)
CAUTION:
• Always disconnect the hose before installing the nose
adapter.
To prevent the surface of workpiece from being scratched
or damaged, use the nose adapter.
Connecting air hose (Fig. 10)
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 coupling 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.
OPERATION
To drive a nail, you may place the contact element against
the workpiece and pull the trigger. (Fig. 11)
CAUTION:
• WITH THE TRIGGER HELD IN A HALF-PULLED
POSITION, an unexpected nailing could occur, if
contact element is allowed to re-contact against the
