FUNCTIONAL DESCRIPTION

CAUTION:
Always disconnect the air hose before adjusting or
•
checking function on the tool.
Adjusting depth of nailing
Fig.3
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.4
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.
Adjusting the shingle guide
Fig.5
Fig.6
The shingle guide is designed for consistent shingle
exposure. Place shingle in desired position.
Turn the lever clockwise to release the adjusting plate.
Reset the tool on the exposed shingle with the projections
of the contact element depressing the bottom of the
previous row of the shingle. Slide the adjusting plate up
against the bottom of the exposed shingle and turn the
lever counterclockwise to lock the adjusting plate.
ASSEMBLY
CAUTION:
Always disconnect the air hose before carrying out
•
any work on the tool.
Loading nailer
Fig.7
Select nails suitable for your work. Depress the latch
lever and open the magazine cap.
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
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, or
Fig.11
Fig.12
2. Pull the trigger first and then place the contact
element against the workpiece.
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.
CAUTION:
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 contact element is allowed to re-
contact against the workpiece or the other surface
under the influence of recoil.
In order to avoid this unexpected nailing, perform
as follows;
− A. Do not place the contact element against the
workpiece with excessive force.
− B. Pull the trigger fully and hold it on for 1-2
seconds after nailing.
For No. (1) method, set the change lever to
•
the position.
For No. (2) method, set the change lever to
the position.
After 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
