2. Inspection and maintenance
Periodically inspect the device.
(1) Remove the four hexagon socket hd. bolts securing
the exhaust cover and remove the exhaust cover.
Then, cylinder, piston, and other parts can be removed
in respective assembly groups.
Wipe the drive bit, the piston sliding part and the body
interior with a cloth to remove deposited dirt.
(2) Confirm that the piston damper offers normal
operation. A damaged piston damper may cause
damage to other component parts.
(3) Carefully check the O-ring for wear while
disassembling. A worn or damaged O-ring may
deteriorate overall performance. Replace a worn or
damaged O-ring with new one.
(4) Prior to reassembling the device, apply grease
(Attolub No. 2 Grease) to the O-ring. Also, lubricate
the device with the recommended oil.
3. Check on mounting screws for each part
At regular intervals check every part for loose
mounting screws and whether or not there are any
air leaks. Retighten any loose screws. Operating the
equipment with loose screws untightened will incur
a hazard.
4. Inspecting the push lever
Check if the push lever (Fig. 1) can slide smoothly.
Clean up the sliding area of the push lever and use the
provided oil for lubrication from time to time.
Lubrication enables smooth sliding and simultaneously
serves to prevent the formation of rust.
5. 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 stapler in a cold weather environment.
Keep the stapler in a warm area.
When not in use, the stapler should be stored in a
warm and dry place.
Keep out of reach of children.
6. Service parts list
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 may be changed without
prior notice.
COMPRESSOR
CAUTION:
When the maximum, operating pressure of the air
compressor 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 unit and the air set to within
10m when using. (Fig. 10)

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
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: 3.9 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.
