1. Prepare the hose
Be sure to use the hose provided with minimum 8
mm (5/16") inside diameter.
NOTE:

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) Load nails in the magazine
Grip the nail guide and knob with fingers. Then
depress the knob to open the nail guide towards the
