Inspection And Maintenance - HIKOKI NV 65HMC Mode D'emploi

4. Changing the exhaust direction
The direction of the exhaust vent can be changed by
turning the top cover (See Fig. 17).
5. Cutting off the sheet
Tear off the output sheet in the direction of the arrow
when using the sheet collated nails (Fig. 18).
6. Using the blow nozzle
CAUTION
○ Be sure to release your fi nger from the trigger before
using the blow nozzle.
○ Do not point the air outlet at a person.
○ Do not use the blow nozzle with the push lever left fi t.
This Nailer has a blow nozzle that blows out wood shavings
which occur during work.
Press the knob with your thumb to use the blow nozzle (See
Fig. 19).
NOTE
○ When the blow nozzle is used for a long time, the nailing
force may degrade temporarily. In this case, allows the
air supply pressure to stabilize before starting work.
○ Oil in the body or drained water from the compressor can
sometimes spout out of the air outlet. It is recommended
that you once conduct a test before use and see if
such phenomenon happens at an environment where
spouted oil will cause any inconvenience.
7. How to use nosecap
CAUTION
Remove the hose from the nailer and release the
compressed air before installing or removing the
nosecap to prevent accidental nail ejection.
○ Attach the nose cap on the tip of the push lever when
you wish to protect the surface of wood, etc., from
scratches.
(1) Attaching and detaching nose cap
The nose cap can be attached by simply pressing it into
the push lever.
Press it in until a convex part inside the nose cap enters
into a hole of the push lever. (Fig. 20)
For removal, insert a thin rod such as a screw driver into
the gap on the back of the push lever, and then pull it
out.
(2) Safekeeping of nose cap
Put the removed nose cap in a space behind the
magazine for safekeeping. (Fig. 21)

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. 22).
(2) Remove the jammed nail with slotted screw driver
(Fig. 23).
(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. Inspecting the push lever
Check if the push lever can slide smoothly (Fig. 24).
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.
4. Inspecting the feeders
(1) Occasionally clean the knob sliding part and then apply
the recommended oil (See Fig. 24).
(2) Open the nail guide and remove dust, etc., as shown
in Fig. 25. Apply lubricant to the sliding groove of the
feeder and shaft. Check the nail stopper (A) and nail
stopper (B) slide smoothly by pushing them with your
fi nger.
(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 fi red 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. 26).
6. Inspecting the muffl er
This Nailer has a built-in muffl er in the exhaust to reduce
noise and stirred-up dust during exhaust.
When the mesh of the muffl er is fi lled or the muffl er
is damaged, replace the muffl er with a new one. To
replace the muffl er, contact our Authorized Service
Center (Fig. 27).
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.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
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.
