To drive a nail, turn the lock lever to the "Free"
position. When not driving nails set the lever to the
"Lock" position (Fig. 2).
CAUTION
Keep the trigger locked at all times except when
driving nails.
3. Lubrication
(1) Prior to operating this nailer, be sure to provide an air
set between the air compressor and this device.
Lubrication through the air set offers smooth
operation, extended service life, and anticorrosion.
Adjust the oiler so that a single drop of oil is supplied
at intervals of 5 to 10 nailing cycles.
(2) It is recommended using the recommended oil (SHELL
TONNA). Other applicable oils are listed. Never mix
two or more types of different oils.
4. 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. 3).
(2) Adjust the position of the nail holder according to the
nail length (Fig. 4).
The nail will not feed smoothly if the nail holder is
not correctly adjusted (Fig. 5).
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. 6).
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. 7).
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. 8).
(4) Close the magazine cover first and swing the nail
guide closed (Fig. 9).
(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. Set the lock lever to "Free" position
Turn the lock lever and align it with the "Free" position
(Fig. 10).
2. How to drive nails
This device is equipped with a mechanism allowing
"intermittent operation" or "continuous operation"
for most effective use according to the type material
the nails will be driven into.
(1) Intermittent operation
Intermittent operation nail driving is used when the
finished appearance is important and when driving a
nail in a particular spot. 1 Press the push-lever up
against the spot where you will drive the nail. 2
Drive the nails one at a time by pulling the trigger
(Fig. 11).
NOTE
Use "intermittent operation" when you are aiming at
a particular spot to drive the nail.
(2) Continuous operation
To drive nails with contact drive: 1 First, pull the
trigger. 2 Then press the nail dispenser up against
the spots you want, to drive the nails one after another
at those spots (Fig. 12).
NOTES
In intermittent operation, you cannot drive nails with
the trigger still held down, by again pressing the
push-lever up against the target spot. To continually
drive nails one after another, release your finger
from the trigger and switch to "continuous operation".
If a nail driver placed on the floor (push-lever pressed
against the floor) is picked up while pulling the trigger,
the nail driver will shift to single shot and it may be
impossible to shoot nails even if the push-lever is
pressed against something. If that happens, release
your finger from the trigger and then try driving nails
again.
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 2
cc 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.
3. Adjusting the nail-driving depth
CAUTIONS
When making adjustments, be sure remove your
finger from the trigger. When making adjustments,
