ADJUSTING AIR PRESSURE

Do not exceed 120 psi (8.3 bar 8.5 kgf/cm
Adjust the air pressure at recommended operating
pressure 70 – 120 psi (4.9 – 8.3 bar 5 – 8.5 kgf/cm
according to the length of nails and the hardness of
workpiece.
The correct air pressure is the lowest pressure which will
do the job. Using the Nailer at a higher than required air
pressure unnecessarily over stresses the Nailer.
