1. Prepare the hose
Be sure to use the hose provided with minimum 8 mm
(5/16") inside diameter.
NOTE
The air supply hoses must have a minimum working
pressure rating of 12.8 bar (180 psi) or 150 percent
of the maximum pressure produced in the air supply
system, whichever is higher.

BEFORE USE
1. Check the air pressure
CAUTION
The air pressure must be constantly maintained at 4.9 –
8.3 bar (70 – 120 psi.).
Adjust the air pressure between 4.9 to 8.3 bar (70 –
120 psi.) according to the diameters and length of nails
and hardness of the wood being nailed. Pay special
attention to the output pressure, capacity, and piping
on the air compressor, so that air pressure does not
exceed the specifi ed limit. Note that excessive pressure
may aff ect overall performance, service life, and safety.
2. 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 off ers 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 diff erent oils.
3. Load Nails
(1) Grip the nail guide and knob with fi nger.
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
counterclockwise.
b. Slide in vertical direction possible.
Lift or lower the nail holder to accept diff erent 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 fi rst 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).
(4) Close the magazine cover fi rst and swing the nail guide
closed (Fig. 7).
(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 fl oor. 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.
