ADJUSTING AIR PRESSURE
WARNING
䢇
Do not exceed 120 psi (8.3 bar 8.5 kgf/
cm2).
Adjust the air pressure at recommended operating
pressure 70 – 120 psi (4.9 – 8.3 bar
5 – 8.5 kgf/cm2) according to the length of staples and
the hardness of workpiece.
The correct air pressure is the lowest pressure which
will do the job. Using the Stapler at a higher than
required air pressure unnecessarily over stresses the
Stapler.
LOADING STAPLES
WARNING
䢇
When loading staples into Stapler,
1) do not pull trigger;
2) do not depress push lever; and
3) keep Stapler pointed downward.
(1) Pull the staple feeder backward, and confirm that
the feeder stopper is securely lodged in the feeder
stopper hole on the staple feeder.

WARNING
䢇
Keep your finger off the trigger except
during fastening operation, because
serious injury could result if the push
lever accidentally contacts you or others
in work area.
䢇
Keep hands and body away from the
discharge area. The Stapler with contact
trip mechanism may bounce from the
recoil of driving a fastener and
unwanted subsequent fastener may be
driven, possibly causing injury.
䢇
Some types of loaded staples can spark
out of the muzzle during a staple driving
operation. Exercise caution!
The SINGLE SEQUENTIAL ACTUATION MECHANISM is
for use where precision fastener placement is desired.
The SINGLE SEQUENTIAL ACTUATION MECHANISM
may reduce the possibility of bodily injury to you or
others in the work area compared to the CONTACT
ACTUATION MECHANISM. This is because it is less
likely to drive an unwanted nail if you keep the trigger

SEQUENTIAL ACTUATION MECHANISM is
recommended to inexperienced users.
NOTE:
䢇
If all warnings and instructions are followed, safe
operation is possible with all three systems:
SINGLE SEQUENTIAL ACTUATION MECHANISM,
CONTACT ACTUATION MECHANISM.
䢇
Always handle staples and package carefully. If
staples are dropped, collating bond may be broken,
which will cause mis-feeding and jamming.
䢇

be sure that:
1) the air pressure to the Stapler remains constant
(regulator is installed and working properly), and
2) the Stapler is always held firmly against the
workpiece.
If staples are driven too deep or shallow into the
workpiece, adjust the stapling in the following order.
1
DISCONNECT AIR HOSE FROM STAPLER.
Adjuster
If staples are driven too deep, turn the adjuster to
the shallow side.
If staples are driven too shallow, turn the adjuster
to the deep side.

Connect the air hose.
ALWAYS WEAR SAFETY GLASSES.
Perform a stapling test.
5
DISCONNECT AIR HOSE FROM STAPLER.
6
Choose a suitable position for the adjuster.
NOTE:
䢇
The staple might not drive deep enough if using
high pressure with the adjuster set upwards
(shallow side) due to factors such as the material
hardness or staple type.
If that happens, reduce pressure and set the
adjuster to lowest position so the staple drives in
at a good position.
