Be sure to use the hose provided with minimum
8 mm (5/16") inside diameter.
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.
Unauthorized persons (including children) must be
kept away from the equipment.
Wear eye protector.
Check the retaining screws which fix the exhaust

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,
