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. 3)
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. 4)

FUNCTIONAL DESCRIPTION

CAUTION:
• Always disconnect the air 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.
Use the nose adapter (Fig. 6)
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. 7)
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. 8)
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. 9)

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 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.
OPERATION
CAUTION:
• Make sure all safety systems are in working order
before operation.
Selecting the operation mode
CAUTION:
• Always make sure that the change lever is properly set
to the position for the desired nailing mode before nail-
ing.
This tool is equipped with the change lever. You can
select either the single sequential actuation mode or the
contact actuation mode with it. (Fig. 11)
Single sequential actuation mode:
You can drive one nail by one sequential operation.
Select this mode when driving a nail carefully and accu-
rately.
To choose this mode, set the change lever to the
position.
Contact actuation mode:
You can drive nails repetitively by placing the contact ele-
ment with the trigger held.
To choose this mode, set the change lever to the
position.
Checking proper action before operation
Before operation, always check following points.
– Make sure that the tool does not operate only by con-
necting the air hose.
– Make sure that the tool does not operate only by pulling
the trigger.
– Make sure that the tool does not operate only by plac-
ing the contact element against the workpiece without
pulling the trigger.
– In single sequential actuation mode, make sure that the
tool does not operate when pulling the trigger first and
then placing the contact element against the work-
piece.
Single sequential actuation
Place the contact element against the workpiece and pull
the trigger fully.
After nailing, release the contact element, and then
release the trigger. (Fig. 12)
CAUTION:
• Do not place the contact element against the workpiece
with excessive force. Also, pull the trigger fully and hold
it on for 1-2 seconds after nailing. Even in the "Single
sequential actuation" mode, half-pulled trigger causes
an unexpected nailing, when the contact element re-
contacts the workpiece.
