(2) It is recommended using the recommended oil (SHELL
TONNA). Other applicable oils are listed. Never mix
two or more types of different oils.
3. Load Nails
(1) Grip the nail guide and knob with finger.
Press the knob down and swing the nail guide open.
And open the magazine cover (Fig. 2).
(2) Adjust the position of the plate according to the nail
length (Fig. 3).
The nail will not feed smoothly if the plate is not
correctly adjusted (Fig. 4).
a. Turn the nail holder about 90 degrees
counterclockwise.
b. Slide in vertical direction possible.
Lift or lower the nail holder to accept different
length nails.
c. Adjust the plate to the nail length reference points
on the magazine cover and turn the nail holder 90
degrees clockwise until you hear "click".
(3) Place the nail coil into the magazine.
Uncoil enough nails to reach the driving hole (Fig. 5).
When using wire collated nails
Insert the first nail into the driving hole and the
second nail between the two pawls of the feeder.
Fit the nail head in the guide slot (Fig. 6).
When using plastic sheet collated nails
Insert the first nail into the driving hole and the
second nail between the two pawls of the feeder.
Fit the nail head and upper side of the plastic sheet in
the guide slot.
Fit the lower side of the plastic sheet in the guide slot
for plastic sheets (Fig. 7).
(4) Close the magazine cover first and swing the nail
guide closed (Fig. 8).
(5) Lock the knob correctly.
NOTE
Be careful not to deform the collated wires and not to
disengage the nails with the guide surface.
Otherwise, the nail guide will not close correctly.
CAUTION
To prevent unintentional 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 properly, nail
feed may 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. 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.
9
They are:
1. Intermittent operation (Trigger fire)
2. Continuous operation (Push lever fire)
(1) Intermittent operation (Trigger fire)
a. Position the nail outlet on the workpiece with
finger off the trigger.
b. Depress the push lever firmly until it is completely
depressed.
c. Pull the trigger to drive a nail.
d. Remove finger from the trigger.
To drive another nail, move the Nailer along the
workpiece and repeat this procedure (Fig. 9).
(2) Continuous operation (Push lever fire)
a. Pull the trigger with the Nailer off the workpiece.
b. Depress the push lever against the workpiece to
drive a nail.
c. 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. 10).
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.
Adjusting the adjuster (Fig. 11)
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 ( mark) (See Fig. 11, 12).
Depth is changed 1 mm with each rotation of the
adjuster.
NOTES
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 does not match the nail-driving
resistance will shorten the life of this nailer.
