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 8.3 bar, 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. 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 unit and the air set to within
10m when using. (Fig. 16)

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 levelat 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
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: 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.
