INSPECTION AND MAINTENANCE

CAUTION:
Be sure to disconnect the hose during cleaning
jams, inspection, maintenance and cleaning.
1. Countermeasure for nail jamming
(1) DISCONNECT AIR HOSE.
(2) Remove all nails.
(3) Release the lock lever and open guide plate (A) (See
Fig. 11).
(4) Remove the jammed nail with a slotted-head
screwdriver (See Fig. 12).
(5) Close guide plate (A) and latch.
(6) In case of frequent jams, consult the Authorized
Service Center from which you bought this machine.
2. Inspecting the magazine
Clean the magazine. Remove dust or wooden chips
which may have accumulated in the magazine. Apply
oil occasionally to the nail rail (See Fig. 13).
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
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 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.

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 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. 14)
