HOW TO USE THE NAILER
CAUTION
○ Do not use the body or any portion of the tool as a
hammer as nails may be discharged unexpectedly or
the tool may become damaged and serious injury could
occur.
○ Take precautions to ensure the safety of persons in the
vicinity during operation.
○ Ensure tool is always safely engaged on the workpiece
and cannot slip.
○ Never carry a pneumatic tool by its hose.
○ Never drag a pneumatic tool by its hose.
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. 8).
Depress the nail outlet onto the desired point; then pull
the trigger to drive a nail in a single shot (See Fig. 10).
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. 10) 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)
Fig. 11).
First, pull the trigger. Then depress the devise onto
the desired position to automatically drive nails (See
Fig. 12).
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 confi 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 nail-driving depth
CAUTION
When making adjustments, be sure remove your fi nger
from the trigger. When making adjustments, be sure
that the nail outlet is not facing downward and that body
parts or other persons are not in the path of the nail
outlet.
○ Adjusting the adjuster (Fig. 13)
Carry out test driving. If the nails are too deep, turn the
adjuster to the shallow side (
If the nail depth is too shallow, turn the adjuster to the
deep side (
Depth is changed 1 mm with each rotation of the
adjuster.
NOTE
○ When adjusting the adjuster, it does not rotate more
than 3 mm from the deepest point where a nail goes
down. Do not rotate the adjuster by force beyond that
point.
○ The nail-driving depth can also be adjusted by changing
the air pressure used. Carry this out together with
movement of the adjuster. Using a high air pressure that
(See
does not match the nail-driving resistance will shorten
the life of this nailer.
3. How to use nosecap
CAUTION
Remove the hose from the nailer and release the
compressed air before installing or removing the
nosecap to prevent accidental nail ejection.
○ Attach the nose cap on the tip of the push lever when
you wish to protect the surface of wood, etc., from
scratches.
(1) Attaching and detaching nose cap
The nose cap can be attached by simply pressing it into
the push lever.
Press it in until a convex part inside the nose cap enters
into a hole of the push lever (Fig. 15).
For removal, insert a thin rod such as a screw driver into
the gap on the back of the push lever, and then pull it
out.
(2) Safekeeping of nose cap
Put the removed nose cap in a space behind the
magazine for safekeeping (Fig. 16).
