the maximum pressure produced in the air supply

system, whichever is higher.

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.
