PREPARATION PRIOR TO OPERATION
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.
2. Check on safety
CAUTIONS
Unauthorized persons (including children) must be
kept away from the equipment.
Wear eye protector.
Check the retaining screws which fix the exhaust
cover, etc. for tightness.
Check the nailer for air leaks and defective or rusty
parts.
Check whether or not the push lever works correctly.
Also check whether or not any dirt has adhered to the
moving parts of the push lever.
Recheck on operational safety.

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 specified limit. Note that
excessive pressure may affect 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 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.
3. Load nails
CAUTIONS
When loading nails into Nailer,
(1) do not depress trigger;
(2) do not depress push lever; and
(3) keep your face, hands feet and other body parts,
as well as those of other persons away from the
nose muzzle to avoid possible injury during usage
and carrying.
Do not insert different length sized nail strips at same
time. If do so, it could result in damaging nail strips
and jamming.
Always point first nail protruded from the nose away
yourself and others.
Keep your face, hands, feet, other body parts as well
as those of other person away from the nose muzzle
to avoid possible injury during usage and carrying.
(1) Align the nail head with nail length indicated on load
slot of the magazine cover, and then load the nails
(See Fig. 2).
(2) Slide the nail strip forward in the magazine.
The nail strip should pass over the nail stopper, which
means it is in proper position (See Fig. 3).
(3) Pull the nail feeder back with depressing the feeder
plate knob to push the nail strip.
NOTE
Use nail strip of more than 5 nails.
The Nailer is now ready to operate.
Removing the nails:

slide the nail feeder forward.
2 Remove the nails from the Nailer.
CAUTION

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.
