BEFORE USE
1. Insert battery into the tool (See Fig. 4)
Do not operate the push lever or trigger while
installing the battery.
Make sure the battery indicator light is flashing GREEN
(See Fig. 5).

– Flashing RED: Insufficient power remaining (The
light turns steady during operation).
– OFF: The battery is extremely empty. Charge the
battery.
Power saving mode
If the tool has not been used for about an one hour
with the battery still installed, Power saving mode
turns on to minimize unnecessary consumption of
battery power. Power saving mode is also activated
when the battery power is extremely low or there's
an abnormality in the machine so please pay attention
to the battery indicator light after deactivating Power
saving mode (by removing the battery and reinstall
it).

The Nailer is now ready to operate.
Removing the nails:
1 Pull the feeder knob backward (See Fig. 12).
2 Return the feeder knob forward quietly while pushing
the nail feeder (B).
3 Pull out nails from the back of the magazine (See Fig.

CAUTION
To prevent unintentional operation, never touch the
trigger or place the top end of the push lever on a

HOW TO USE THE NAILER
CAUTION
Never use the top cover or housing of this device as a
hammer.
Take precautions to ensure the safety of persons in
the vicinity during operation.
Squeeze the trigger when drive a nail, otherwise the
piston can not return correctly.
Make sure the nailing depth when the temperature is
above 40°C or below 0°C.
1. Nailing procedures
This power tool is equipped with a FULL SEQUENTIAL
ACTUATION MECHANISM.
(1) Intermittent nailing
Depress the nail outlet onto the desired point; then pull
the trigger to drive a nail in a single shot (See Fig. 14).
After nailing once, nailing will not be possible again
until the trigger is released and pressed again.
(2) Push lever
When depressing the nail outlet, be sure to fully lift
the push lever (See Fig. 14) to release the safety lock.
Thus, nails cannot be driven without releasing the
safety lock even though the trigger is pulled.
The machine employs a preventive mechanism for
unloaded operation.
The machine enters a state where the push lever
cannot be pushed up. This takes place when the
magazine is not loaded with nails or when the
remaining number of nails becomes less than 8 or 9
(NR90GC), 5 or 6 (NR90GR).
CAUTION
Exercise care when nailing corners of lumber. When
continuous nailing corners of lumber, a nail may go
astray or break through the corner.
Do not drive a nail on another nail.
Do not drive a nail on metal parts.
Use caution not to throw the push lever tip onto wood
when the push lever cannot be pushed up.
NOTE
Under low temperature conditions, the tool
sometimes does not operate correctly. Always operate
the tool at the appropriate ambient temperature.
2. Adjusting the nailing depth (See Fig. 16, 17)
To assure that each nail penetrates to the same depth,
be sure that the tool is always held firmly against the
workpiece.
If nails are driven too deep or shallow into the
workpiece, adjust the nailing in the following order.
1 Remove the fuel cell and the battery from the tool
(See Fig. 15).
