PREPARATION PRIOR TO OPERATION
1. Prepare the hose
Be sure to use the hose provided with minimum 8
mm (5/16") inside diameter.
Piston reciprocating
4.9 – 8.3 bar (70 – 120 psi.)

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
(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).
