4. Inspecting the feeders
(1) Occasionally clean the knob sliding part and then
apply the recommended oil (See Fig. 18).
(2) Open the nail guide and remove dust, etc., as shown
in Fig. 19. Apply lubricant to the sliding groove of the
feeder and feeder shaft. Check sub nail stopper slide
smoothly by pushing them with your finger.
(3) Also, apply the recommended oil to the feeding surface
of the nose and nail guide after cleaning. This promotes
smooth operation and retards corrosion.
CAUTION
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.
5. Inspecting the magazine
Clean the magazine. Remove dust of wooden chips
which may have accumulated in the magazine.
6. Storing
When not in use for an extended period, apply a thin
coat of the lubricant to the steel parts to avoid rust.
Do not store the Nailer in a cold weather environment.
Keep the Nailer in a warm area.
When not in use, the Nailer should be stored in a warm
and dry place.
Keep out of reach of children.

CAUTION
Repair, modification and inspection of Hitachi Power
Tools must be carried out by an Hitachi Authorized
Service Center.
This Parts List will be helpful if presented with the tool
to the Hitachi Authorized Service Center when
requesting repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
MODIFICATIONS
Hitachi Power Tools are constantly being improved
and modified to incorporate the latest technological
advancements.
Accordingly, some parts (i.e. code numbers and/or
design) may be changed without prior notice.
COMPRESSOR
CAUTION
When the maximum, operating pressure of the air com-
pressor 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 nailer and the air set to within 10 m
when using (See Fig. 20).

Noise Information
Noise characteristic values in accordance with Dr prEN
792-13, JUNE, 1997:
The typical A-weighted single-event sound power level
The typical A-weighted single-event emission sound
pressure level at work station
These values are tool-related characteristic values and
do not represent the noise development at the point of
use. Noise development at the point of use will for
example depend on the working environment, the
workpiece, the workpiece support and the number of
driving operations, etc.
Depending on the conditions at the workplace and the
form of the workpiece, individual noise attenuation
measures may need to be carried out, such as placing
workpieces on sound-damping supports, preventing
workpiece vibration by means of clamping or covering,
adjusting to the minimum air pressure required for the
operation involved,etc.
In special cases it is necessary to wear hearing protection
equipment.
Vibration Information
The typical vibration characteristic value in accordance
with Dr prEN 792-13, JUNE,1997 does not exceed 2.5 m/s
This values is a tool-related characteristic value and does
not represent the influence to the hand-arm-system
when using the tool. An influence to the hand-arm-
system when using the tool will for example depend on
the gripping force, the contact pressure force, the working
direction, the adjustment of energy supply, the workpiece,
the workpiece support.
