CAUTIONS
䡬
To prevent unintentional operation, never touch the
trigger or place the top end of the push lever on a
work bench on floor. Also, never face the nail outlet
toward any part of a person.
HOW TO USE THE NAILER
CAUTIONS
䡬
Never use the head or body of this device as a
hammer.
䡬
Take precautions to ensure the safety of persons in
the vicinity during operation.
1. Nailing procedures
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. 3
).
Fig. 3
Whether you set the trigger pin (See
Fig. 4
) 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).

CAUTION
䡬
Excercise care when nailing corners of lumber. When
continuous nailing corners of lumber, a nail may go
astray or break through the corner.
䡬
Do not drive a nail on another nail.
䡬
Do not drive a nail on metal parts.
NOTES
䡬
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 confirm the
amount of remaining nails. On the other hand, all nails
should be removed after using this nailer.
䡬
After completing operation, put into the body 5–10
drops oil through the hose joint to protect the tool
from rust.
䡬
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. 5)
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 firmly 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.
