CAUTION
To prevent unintentional operation, never touch the
trigger or place the top end of the push lever on a work
bench on
fl
oor. Also, never face the nail outlet toward
any part of a person.
HOW TO USE THE NAILER
CAUTIONS
○
Never use the head or body of this device as a hammer.
○
Take precautions to ensure the safety of persons in the
vicinity during operation.
1. Nailing procedures
This HiKOKI nailer is equipped with a nailer operation
switching device.
Use SINGLE SEQUENTIAL ACTUATION MECHANISM
or CONTACT ACTUATION MECHANISM in accordance
with the work to be performed.
(1) Intermittent nailing
Set the switching device to the upward position (to set
to SINGLE SEQUENTIAL ACTUATION MECHANISM)
(See
Fig. 3
).
Depress the nail outlet onto the desired point; then pull
the trigger to drive a nail in a single shot (See
Fig. 4
).
After nailing once, nailing will not be possible again until
the trigger is released and pressed again.
WARNING
A nail will
fi
re each time the trigger is depressed as long
as the push lever remains depressed.
CAUTION
If you do not pull the trigger quickly and crisply while in
the single shot mode, the nailer will bounce and shoot
several nails instead of just one. To avoid this, be sure
to pull the trigger quickly and crisply.
(2) Push lever
When depressing the nail outlet, be sure to fully lift the
push lever (See
Fig. 4
) to release the safety lock. Thus,
nails cannot be driven without releasing the safety lock
even though the trigger is pulled.
(3) Continuous nailing
Set the switching device to the downward position (to
set to CONTACT ACTUATION MECHANISM) (See
Fig. 5
).
First, pull the trigger. Then depress the devise onto
the desired position to automatically drive nails (See
Fig. 6
).
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 pulled and
accidentally bump the push lever against yourself or
others.
The SINGLE SEQUENTIAL ACTUATION MECHANISM
may also reduce the speed of operation compared to
the CONTACT ACTUATION MECHANISM. The SINGLE
SEQUENTIAL ACTUATION MECHANISM is recommended
to inexperienced users.
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.
NOTE
○
Precautions on no-load operation
Sometimes nailing will continue after driving in all nails
previously contained in the magazine.
This is termed “no-load operation”. Such operation may
deteriorate the damper, magazine, and nail feeder.
To avoid no-load operation, occasionally con
fi
rm the
amount of remaining nails. On the other hand, all nails
should be removed after using this nailer.
○
Always handle nails and package carefully. If nails
are dropped, collating bond may be broken.
○
After nailing:
(1) disconnect air hose from the nailer;
(2) remove all nails from the nailer;
(3) supply 5 – 10 drops of HiKOKI pneumatic tool
lubricant into the air plug on the nailer; and
(4) open the petcock on the air compressor tank to
drain any moisture.
○
Under low temperature conditions, the machine
sometimes does not operate correctly. Always operate
the machine at the appropriate ambient temperature.
2. Adjusting the nailing depth (See Fig. 7)
To assure that each nail penetrates to the same depth,
be sure that:
(1) the air pressure to the Nailer remains constant
(regulator is installed and working properly), and
(2) the Nailer 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
DISCONNECT AIR HOSE FROM NAILER.
2
If nails are driven too deep, turn the adjuster to the
shallow side.
If nails are driven too shallow, turn the adjuster to
the deep side.
3
Stop turning the adjuster when a suitable position is
reached for a nailing test.
4
Connect the air hose.
ALWAYS WEAR EYE PROTECTOR.
Perform a nailing test.
5
DISCONNECT AIR HOSE FROM NAILER.
6
Choose a suitable position for the adjuster.
3. Using the nose cap (See Fig. 8)
CAUTION
When detaching or attaching the nose cap, be sure to
remove your
fi
nger from the trigger and disconnect the
air hose from the nailer.
The nose cap is attached to the push lever tip to protect
the workpiece from scratches or damage. Remove in
the order shown below when not using.
(1) DISCONNECT AIR HOSE FROM NAILER.
(2) Pull out the nose cap in the direction of the arrow as
shown in the diagram.
○
Attach to the tip of the push lever in the reverse order of
detaching.
INSPECTION AND MAINTENANCE
CAUTION
Be sure to disconnect the hose during cleaning jams,
inspection, maintenance and cleaning.
1. Inspecting the magazine
1
DISCONNECT AIR HOSE.
2
Clean the magazine. Remove paper chips or wooden
chips which may have accumulated in the magazine.
Lubricate it with HiKOKI pneumatic tool lubricant.
