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 inter-
nal diameter of over 8.5 mm (5/16") 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
30 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 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.
FUNCTIONAL DESCRIPTION
Nose adapter (Fig. 5 & 6)
CAUTION:
• Always lock the trigger and disconnect the hose before
installing or removing the nose adapter.
When nailing workpieces with easily-marred surfaces,
use the nose adapter. It is stored in the holder on the
reverse side of the magazine.
Attach the nose adapter to the contact arm. When not in
use, store the nose adapter in the holder on the reverse
side of the magazine to keep it from being lost.
Adjusting depth of nailing (Fig. 7)
CAUTION:
• Always lock the trigger and disconnect the hose before
adjusting the depth of nailing.
To adjust the depth of nailing, turn the adjuster so that
the arrow above the adjuster will point to the number indi-
cated 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.
ASSEMBLY
Loading nailer (Fig. 8 & 9)
CAUTION:
• Always lock the trigger and disconnect the hose before
loading the nailer.
Select nails suitable for your work. Insert strip of nails
into the magazine.
Pull the pusher lever to the rear to engage the pusher to
the last nail.
Unloading nailer (Fig. 10 & 11)
CAUTION:
• Always disconnect the air hose before unloading the
nailer.
Pull the pusher lever to the rear. Return the pusher lever
back while keeping the pusher depressed to disengage it
from the strip of nails.
Depress the nail stopper and remove the strip of nails
from the magazine.
Connecting air hose (Fig. 12)
Lock the trigger. 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 fit-
ting. 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
CAUTION:
• Make sure all safety systems are in working order
before operation.
1. To drive a nail, you may place the contact element
against the workpiece and pull the trigger
(Fig. 13) ,
or
2. Pull the trigger first and then place the contact ele-
ment against the workpiece.
(Fig. 14)
However when the tool is set to the “Intermittent Nailing”
mode, WITH THE TRIGGER HELD IN A HALF-PULLED
POSITION, an unexpected nailing could occur, if the con-
tact element is allowed to re-contact against the work-
piece or the other surface under the influence of recoil.
In order to avoid this unexpected nailing, perform as fol-
lows;
1.
Do not place the contact element against the work-
piece with excessive force.
2. Pull the trigger fully and hold it on for 1 – 2 seconds
after nailing.
No. 1 method is for intermittent nailing, when you wish to
drive a nail carefully and very accurately.
No. 2 method is for continuous nailing.
For No. 1 method, set the change lever to the “Intermit-
tent Nailing” position. For No. 2 method, set the change
lever to the “Continuous Nailing” position. Before using
the change lever to change the nailing method, always
make sure that the change lever is properly set to the
position for the desired nailing method.

Anti dry fire mechanism
This tool is equipped with an anti dry fire mechanism.
When there are a few nails remaining in the magazine,
the contact arm will be locked in the undepressed posi-
tion to prevent the tool from being activated. Load more
nails to resume operation.
