2. Efficient work
(1) The Nailer may take a long time to shoot
a nail when the operating pressure is low,
or hard timber or long nails are used. In
such cases, it is advisable to set the
operating air pressure to 100 – 20 psi (6.8
– 8.3 bar, 7 – 8.5 kgf/cm
work.
(2) When the Nailer is pressed firmly or used
continuously, it may become inoperative
due to decreased pressure of the air
compressor. In such cases, wait until the
air compressor's pressure increases
sufficiently to use the Nailer.
3. Precautions on idle shooting
NOTE:
"Idle shooting" means that the Nailer is
pressed and operated even though no
nail is shot or the Nailer continues to be
pressed and operated even after a nail is
shot. If idle shooting is continued, each
part of the Nailer may be affected. Take
extra care not to do idle shooting.
After nailing:
1) disconnect air hose from the Nailer;
2) remove nail from the Nailer;
3) supply 10 drops min. of Hitachi
pneumatic tool lubricant into the air
plug on the Nailer; and
4) open the petcock on the air
compressor tank to drain any
moisture.
