Nose adapter (Accessory)
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.
Attach the nose adapter to the contact element. (Fig. 7)
Adjusting depth of nailing (Fig. 8)
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 a lower air pressure and
the adjuster set to a deeper depth of nail driving.
CAUTION:
• Always lock the trigger and disconnect the hose before
adjusting the depth of nailing.
Installing the hook (Fig. 9)
CAUTION:
• Always lock the trigger and 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.
To use the hook, simply lift up hook until it snaps into the
open position.
When not in use, always lower hook until it snaps into the
closed position.
ASSEMBLY
CAUTION:
• Always lock the trigger and disconnect the hose before
carrying out any work on the tool.
Loading the nailer (Fig. 10)
Select nails suitable for your work. Insert strip of nails into
the magazine. (Fig. 11)
Load nails so that they get parallel to the driver guide.
(Fig. 12)
Pull the pusher lever to the rear to engage the pusher to
the last nail.
Unloading nailer (Fig. 13)
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. (Fig. 14)
Connecting the air hose (Fig. 15)
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 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
CAUTION:
• Make sure all safety systems are in working order
before operation.
Selecting the operation mode
CAUTION:
• When not in use, always set the change lever to the
trigger lock position.
• Always make sure that the change lever is properly set
to the position for the desired nailing mode before
nailing.
This tool is equipped with the change lever. You can
select either the single sequential actuation mode or the
contact actuation mode with it. You can also lock the
trigger by setting it to the trigger lock position. (Fig. 16)
Single sequential actuation mode:
You can drive one nail by one sequential operation. Select
this mode when driving a nail carefully and accurately.
To choose this mode, set the change lever to the
position.
Contact actuation mode:
You can drive nails repetitively by placing the contact
element 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
connecting 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
placing 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
workpiece.
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. 17)
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.
