the maximum pressure produced in the air supply

system, whichever is higher.

kept away from the equipment.

⅜ Wear eye protector.

⅜ Check the retaining screws which fix the exhaust

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.
