○ 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.
Filter ............ The fi lter removes moisture and dirt
mixed in compressed air.
Drain daily unless fi tted with an
automatic drain.
Keep the fi lter clean by regular
maintenance.
