Hitachi NV 45AB3 Mode D'emploi page 11

If nails are driven too shallow, turn the adjuster
clockwise while pulling it downward.
When the adjuster is released, it return upward.
Furthermore, turn the adjuster until it reaches a position
where it gets fixed with a clock. (Fig. 11)
The adjuster can be fiexed each at 1/4 rotation.
The adjuster moves approximately 0.25mm per 1/4
rotation.
c. Stop turning the adjuster when a suitable position is
reached for a nailing test.
d. Connect the air hose.
ALWAYS WEAR EYE PROTECTOR.
Perform a nailing test.
e. DISCONNECT AIR HOSE FROM NAILER.
f. Choose a suitable position for the adjuster.
NOTE:
The nail-driving depth can also be adjusted by changing
the air pressure used. Carry this out together with
movement of the adjuster. Using a high air pressure
that does not match the nail-driving resistance will
shorten the life of this nailer.
INSPECTION AND MAINTENANCE
CAUTION
Be sure to disconnect the hose during cleaning
jams, inspection, maintenance and cleaning.
1. Countermeasure for nail jamming
(1) Remove the nail roll from the magazine, open the nail
guide, insert a rod into the outlet and tap the rod with
a hammer. (Fig. 12).
(2) Remove the jammed nail with slotted screwdriver.
(Fig. 13)
(3) Cut off the defective part of the steel wire which links
the nails with cutting nippers, correct the deformation,
then load the nail roll in the magazine.
(4) In case of frequent jams, consult the Authorized Service
Center from which you bought this machine.
2. 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.
3. Protection against dirt
Remove dirt from the inlet port and interior of the
hose.
Use only clean oil to protect the air intake port and
sliding part against clogging or damage.
4. Inspecting the feeders
(1) Occasionally clean the knob sliding part and then
apply the recommended oil. (See Fig. 14)
(2) Open the nail guide and remove dust, etc., as shown
in Fig. 15. Apply lubricant to the sliding groove of the
feeder and feeder shaft. Check the main nail stopper
and sub nail stopper slide smoothly by pushing them
with your finger.
(3) Also, apply the recommended oil to the feeding sur-
face 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. Cleaning and removal of tar and dirt
Adhesion of tar and dirt to areas around the discharge
outlet, push lever or nail feed parts will interfere with
proper operation.
Please clean and remove tar and dirt with kerosene, #2
fuel oil or diesel fuel.
CAUTION
Never use gasoline or other similar highly volatile
liquids for cleaning. Vapors of such liquids inside the
power tool could be ignited by sparks produced during
nailing and cause an explosion.
Never use kerosene to oil the tool.
(1) Please immerse only the area around the discharge
outlet in solvent and do not immerse the cylinder or
magazine.(See Fig. 16)
CAUTION
Do not immerse the nailer in solvent. Plastic parts and
the O-ring etc. may be demaged.
(2) Throughly dry the power tool. If any oily film from the
solvent remains, it will promote adhesion of tar and
frequent cleaning will be necessary.
(3) After cleaning check that the push lever, the spring to
return the push lever, and the feeder move smoothly.
CAUTION
The push lever must be free to move without sticking
or binding. The spring must positively return the push
lever to its down position whenever the push lever is
released from being held in its up position.
6. Inspecting the magazine
Clean the magazine. Remove dust of wooden chips
which may have accumulated in the magazine.
7. 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 ot in use, the Nailer should be stored in a warm
and dry place.
Keep out of reach of children.
8. 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 re-
questing 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.
