1. Nailing procedures
CAUTIONS:
NOTES:
2. Adjusting the nailing depth (See Fig. 7)
Gap
(1) the air pressure to the Nailer remains constant
(2) the Nailer is always held firmly against the workpiece.
3. Changing the exhaust direction
Take precautions to ensure the safety of persons in
the vicinity during operation.
This product is a nailer using a sequential trip (single-
shot) mechanism. If you pull the trigger first, nothing
will happen even if you press the push lever up against
an object.
First, press the push lever against the object to the
desired position, then pull the trigger to drive the nail
into the object (See Fig. 5).
Whether you set the trigger pin (See Fig. 6) up or
down, you cannot drive a nail by first pulling on the
trigger and then pressing the push lever against an
object (continuous nailing).
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.
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 bumper, magazine, and nail
feeder.
To avoid no-load operation, occasionally confirm 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 Hitachi pneumatic tool
lubricant into the air plug on the nailer; and
(4) open the petcock on the air compressor tank to
drain any moisture.
To assure that each nail penetrates to the same depth,
be sure that:
(regulator is installed and working properly), and
If nails are driven too deep or shallow into the
workpiece, adjust the nailing depth in the following
order.
1 Disconnect air hose.
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 protection.
Perform a nailing test.
5 Disconnect air hose.
6 Choose a suitable position for the adjuster.
The direction of the exhaust vent can be changed by
turning the top cover (See Fig. 8).
