(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. Inspect the Trigger
Periodically clean the sliding parts of the trigger, and
make sure that the trigger moves smoothly (Fig. 24).
6. Inspecting the muffler
This Nailer has a built-in muffler in the exhaust to
reduce noise and stirred-up dust during exhaust.
When the mesh of the muffler is filled or the muffler
is damaged, replace the muffler with a new one. To
replace the muffler, contact our Authorized Service
Center (Fig. 25).
7. Inspecting the magazine
Clean the magazine. Remove dust of wooden chips
which may have accumulated in the magazine.
8. 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.

C: No. Used
D: Remarks
CAUTION
Repair, modification and inspection of Hitachi Power
Tools must be carried out by a 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
compressor exceeds 23 bar (320 psi.), be sure to
provide a reducing valve between the air compressor
and nailer. Then, adjust the air pressure within the
operating range of 12 – 23 bar (170 – 320 psi.). If the
air set is installed, lubrication is also possible, thus
providing additional convenience.

Noise Information
Noise characteristic values in accordance with EN 792-
13, JUNE, 2000:
The typical A-weighted single-event sound power level
The typical A-weighted single-event emission sound
pressure level at work station
Uncertainty KpA: 2.5 dB (A)
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
operaion involved,etc.
In special cases it is necessary to wear hearing protection
equipment.
Vibration Information
The typical vibration characteristic value in accordance
with EN 792-13, JUNE, 2000 : 4.8 m/s
2
Uncertainty K = 1.5 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.
