(6) Lock the knob completely.
CAUTION
To prevent unitentional operation, never touch the
trigger or place the top end of the push lever on a work
bench or floor. Also, never face the nail outlet toward
any part of a person.
NOTE
Before loading the nails in the magazine, position the
nail holder according to the length of the nail. If the nail
holder position is not adjusted, the nail jam. If the
cover is forcibly closed without adjusting the position
of the nail holder, the nail holder may be damaged.
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
NOTE
For nailing asphalt composition shingles the correct
air pressure is that which will drive the nail, so that the
underneath side of the nail touches or creases the top
surface of the shingle without breaking or cutting it.
This Nailer is equipped with the push lever and does not
operate unless the push lever is depressed (upward
position).
There are two methods of operation to drive nails with
this Nailer.
They are:
1. Intermittent operation (Trigger fire):
2. Continuous operation (Push lever fire):
(1) Intermittent operation (Trigger fire)
1 Position the nail outlet on the workpiece with
finger off the trigger.
2 Depress the push lever firmly until it is completely
depressed.
3 Pull the trigger to drive a nail.
4 Remove finger from the trigger.
To drive another nail, move the Nailer along the
workpiece and repeat this procedure. (Fig. 6)

when using on hard materials. In such cases, fire the
nails by squeezing and quickly releasing the trigger.
(2) Continuous operation (Push lever fire)
1 Pull the trigger with the Nailer off the workpiece.
2 Depress the push lever against the workpiece to
drive a nail.
3 Move the Nailer along the workpiece with a
bouncing motion.
Each depression of the push lever will drive a nail.
As soon as the desired number of nails have been
driven, remove finger from the trigger. (Fig. 7)

CAUTION:
Exercise care when nailing corners of lumber. When
continuous nailing corners of lumber, a nail may go
astray or break through the corner.
NOTES:
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.
After completing operation, put into the body about
2cc oil through the hose joint to protect the tool from
rust.
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
CAUTIONS:
When making adjustments, be sure remove your
finger 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.
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.
