(3) Also, apply the recommended oil to the feeding

surface of the tail cover and nail guide after cleaning.
This promotes smooth operation and retards
corrosion.

CAUTION:

䡬

Check for smooth movement of the feeders and
stoppers before use. If movement is uneven, nails
could be fired at an irregular angle, presenting a
hazard to the operator and others nearby.

COMPRESSOR

CAUTION:

䡬

When the maximum, operating pressure of the air
compressor exceeds 8.3 bar (120 psi.), be sure to
provide a reducing valve between the air compressor
and nailer. Then, adjust the air pressure within the
operating range of 4.9 ~ 8.3 bar (70 ~ 120 psi.). If the
air set is installed, lubrication is also possible, thus
providing additional convenience.

OILER-FILTER-REDUCING VALVE (Air Set)

So that the equipment can be operated under an optimum
condition to ensure extended service life, it is advisable
to use an oiler filter reducing valve. Please limit the
length of the hose between the unit and the air set to
within 10m when using.
