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

) for efficient

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:

䢇 ”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.

䢇 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.
