LUBRICATION
It is important that the Nailer be properly
lubricated.
Without proper lubrication, the Nailer will not
work properly and parts will wear
prematurely.
䡬 Use Hitachi pneumatic tool lubricant.
Do not use detergent oil or additives.
These lubricants will harm the O-rings
and other rubber parts. This will cause
the Nailer to malfunction.
䡬 Filter-regulator-lubricator units should
always be used.
Keep the lubricator filled with Hitachi
pneumatic tool lubricant.
䡬 If a lubricator is not available, supply 10
drops min. of Hitachi pneumatic tool
lubricant into the air plug on the Nailer
every 100 shots.
COLD WEATHER CARE
䡬 Do not store the Nailer in a cold weather
environment.
Keep the Nailer in a warm area until
beginning the work.
䡬 If the Nailer is already cold, bring it in a
warm area and allow the Nailer to warm
up before use.

bar 4.5 kgf/cm
2
).
2 Remove nail from the Nailer.
3 Connect the air hose and free-fire
(blank-fire) the Nailer.
The lowered air pressure will be
enough to free-fire the Nailer.
Slow speed operation tends to warm
up the moving part.
CAUTION
䢇 Do not free-fire the Nailer at high
pressure.
01Eng_NH90AB_US 8/31/09, 2:53 PM11
— 12 —
English
䡺 THE NAILER MUST NOT OPERATE.

twice when connecting an air hose, but
it is a normal phenomenon.
ADJUSTING AIR PRESSURE
WARNING
䢇 Do not exceed 120 psi (8.3 bars 8.5 kgf/
cm
2
).
Adjust the air pressure at recommended
operating pressure 70 – 120 psi (4.9 – 8.3 bar
5 – 8.5 kgf/cm
2
) according to the length of

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
2
) 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.
