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

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

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 (NR90GC2), 5 or 6
(NR90GR2).
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
fi
rmly 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
).
2
If nails are driven too deep, move the push lever to
forward (See
Fig. 16
).
If nails are driven too shallow, move the push lever
to backward (See
Fig. 17
).
3
Stop moving the push lever when a suitable position
is reached for a nailing test.
4
Connect the fuel cell and the battery to the tool.
ALWAYS WEAR EYE PROTECTOR.
Perform a nailing test.
5
Remove the fuel cell and the battery from the tool.
6
Choose a suitable position for the push lever.
3. Clearing a jam
If nails are jammed in
fi
ring head, remove it, and adjust
the nailing in the following order.
1
Remove the fuel cell and the battery from the Nailer.
(See
Fig. 15
)
2
Lock follower back in magazine and remove
fasteners.
