OPERATION
CAUTION:
Make sure all safety systems are in
working order before operation.
Selecting the operation mode
CAUTION:
Always make sure that the actua-
tion mode selector is properly set to the position
for the desired stapling mode before stapling.
► Fig.17: 1. Actuation mode selector
Single sequential actuation mode:
You can drive one staple by one sequential operation.
Select this mode when driving a staple carefully and
accurately.
To choose this mode, set the actuation mode selector to
the position.
Contact actuation mode:
You can drive staples repetitively by placing the contact
element with the trigger held.
To choose this mode, set the actuation mode selector 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 stapling, release the contact element, and then
release the trigger.
► Fig.18
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 stapling.
Even in the "Single sequential actuation" mode, half-
pulled trigger causes an unexpected stapling, when
the contact element re-contacts the workpiece.
Contact actuation
Pull the trigger first and then place the contact element
against the workpiece.

Empty indicator
When the remaining number of staples in the magazine
becomes low, the empty indicator turns to red. Reload
the staples when the empty indicator becomes red.

Removing jammed staples
CAUTION:
Always return the trigger and
disconnect the hose before removing jammed
staples.
CAUTION:
Do not use deformed staples or
strip of staples. Failure to do so causes poor staple
feeding.
NOTE: Always hold the rear of the sliding door when
you press the lever. The sliding door opens suddenly
with the lever pressed when staples are stored in the
magazine.
Follow the procedure of "Removing staples" to remove
the strip of staples, and remove jammed staples from
the staple rail.
MAINTENANCE
CAUTION:
Before attempting to perform
inspection or maintenance, always release the
trigger and disconnect the air hose from the tool.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
Staples
Handle staple strips and their box carefully. If the staple
strips have been handled roughly, they may be out of
shape, causing poor staple feed.
Avoid storing staples in a very humid or hot place or
place exposed to direct sunlight.
Maintenance of stapler
Always check the tool for its overall condition and loose
screws before operation. Tighten as required.
With tool disconnected, make daily inspection to assure
free movement of the contact element and trigger. Do
not use tool if the contact element or trigger sticks or
binds.
