DANGER

● NEVER

use

oxygen or

other

bottled

gases.

Explosion

may

occur.

 

WARNING

●Never connect Nailer to pressure which potentially exceeds 200 psi (13.7 bar 14 kgf/cm2).

●Never use non relieving coupler on Nailer.

1.Power source

○Use only clean, dry, regulated compressed air as a power source for this Nailer.

○Aircompressorsusedtosupplycompressed air to this Nailer must comply with the requirements of the latest version of ANSI Standard B 19.3 “Safety Standard For Compressors For Process Industries.”

○Moisture or oil in the air compressor may accelerate wear and corrosion in the Nailer.

Drain daily.

2.Filter-Regulator-Lubricator

○Use a regulator with a pressure range of 0 –

120 psi (0 – 8.3 bar 0 – 8.5 kgf/cm2).

○Filter-regulator-lubricator units supply an optimum condition for the Nailer and extend the Nailer life. These units should always be

used.

Drain daily unless fitted with an automatic drain.

Keep the filter clean by regular maintenance.

Regulator

The regulator controls the operating pressure for safe operation of the Nailer. Inspect the regulator before operation to be sure it operates properly.

Lubricator

The lubricator supplies an oil mist to the Nailer.

Inspect the lubricator before operation to be sure the supply of lubricant is adequate. Use Hitachi pneumatic tool lubricant.

Air hose

 

 

 

 

 

 

 

Air hose must have a minimum working

 

pressure rating of 150 psi (10.4 bar 10.6

 

kgf/cm2) or 150% of the maximum pressure

 

produced in the system, whichever is
