Working Environment - Hitachi NT 65MA4 Manuel D'instructions Et De Sécurité

Working environment

● No fl ammable gas, liquid or other
fl ammable objects at worksite.
● Clear the
unauthorized personnel.
Air supply
● Never connect Nailer to pressure
which potentially exceeds 200 psi
(13.7 bar 14 kgf/cm
● Never use non relieving coupler on
Nailer.
1. Power source
○ Use only clean, dry, regulated compressed
air as a power source for this Nailer.
○ Air compressors used to supply compressed
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/cm
○ Filter-regulator-lubricator units supply an
optimum condition for the Nailer and extend
the Nailer life. These units should always be
used.
