Hitachi NV 90HMC Handling Instructions Manual page 38

English
○ If merely pushing the push lever against the material
to be nailed causes the sound of drive bit movement
to occur, the power tool is faulty. Furthermore, with
regard to the push lever, please note that it must
never be modifi ed or removed.
10. Use specifi ed nails only.
Never use nails other than those specifi ed and
described in these instructions.
11. Be careful when connecting the hose.
When connecting the hose and loading nails in order
not to fi re the tool by mistake, make sure of the following.
○ Do not touch the trigger.
○ Do not allow the fi ring head to contact with any
surface.
○ Keep the fi ring head down.
Strictly observe the above instructions, and always
make sure that no part of the body, hands or legs is
ever in front of the nail outlet.
12. Do not carelessly place your fi nger on the trigger.
Do not place your fi nger on the trigger except when
actually nailing. If you carry this tool or hand it to
someone while having your fi nger on the trigger, you
may inadvertently discharge a nail and thus cause an
accident.
13. Completely Close the nail guide and do not open it
during operation.
If nailing is attempted when the nail guide is open, nails
will not be driven into the timber, and there is a risk of
dangerous discharge.
14. Press the nail outlet fi rmly against the material to
be nailed.
When driving in nails, press the nail outlet fi rmly against
the material to be nailed. If the outlet is not applied
properly, the nails may rebound.
15. Keep hands and feet away from the fi ring head
when using.
It is very dangerous for a nail to hit the hands or feet by
mistake.
16. Beware of the tool's kickback
Do not approach the top of the tool with your head etc.
during operation. This is dangerous because the tool
may recoil violently if the nail currently being driven in
comes into contact with a previous nail or a knot in the
wood.
17. Take care when nailing thin boards or the corners
of wood.
When nailing thin boards, the nails may pass right
through, as may also be the case when nailing the
corners of wood due to deviation of the nails. In such
cases, always make sure that there is no one (and
nobody's hands or feet; etc.) behind the thin board or
next to the wood you are going to nail.
18. Simultaneous nailing on both sides of the same
wall is dangerous
Under no circumstances should nailing be performed
on both sides of a wall at the same time. This would be
very dangerous since the nails might pass through the
wall and thus cause injuries.
19. Do not use the power tool on scaff oldings, ladders.
The power tool shall not be used for specifi c application
for example:
– when changing one driving location to another
involves the use of scaff orldings, stairs, ladders or
ladder alike constructions, e.g. roof laths,
– closing boxes or crates,
– fi tting transportation safety systems e.g. on vehicles
and wagons

20. Do not disconnect the hose with your fi nger on the
trigger.
If you disconnect the hose with your fi nger on the
trigger, the next time the hose is connected, there is a
danger that the power tool will fi re a nail spontaneously,
or operate incorrectly.
21. Disconnect the hose and take out any nails left in
the magazine after use.
Disconnect tool from air before doing tool maintenance,
cleaning a jammed fastener, leaving work area, moving
tool to another location, or after use. It is very dangerous
for a nail to be fi red by mistake.
22. When removing a nail which has become stuck,
make sure to fi rst of all disconnect the hose and
release compressed air.
When removing a nail which has become stuck in the
nail outlet, fi rst of all make sure to disconnect the hose
and release compressed air inside the power tool.
Accidental fi ring of the nail could be very dangerous.
23. To avoid hazards caused by falling nails, never
open the magazine with the device facing
downward while loading nails.
24. A female plug (air socket) should not be used in
the body.
If a female plug is installed in the body, the compressed
air sometimes can not be drawn when the hose is
disconnected so avoid this.
The tool and air supply hose must have a hose coupling
such that all pressure is removed from the tool when the
coupling joint is disconnected.
25. Do not remove the dust cover
Never operate with the dust cover removed in order
to avoid the danger of breakage of the wire or plastic
retaining the nails or missed-fi red nails fl ying about.
26. Disconnect the air hose before operating the nose
switch lever.
Be sure to disconnect the air hose before operating
the nose switch lever. Otherwise, you run the risk of
accidentally fi ring nails.
27. When attaching and detaching the nose cap,
disconnect the hose.
When attaching the accessory nose cap to the tip of
the push lever and when detaching it, make sure to
disconnect the hose beforehand. It is very dangerous
for a nail to be fi red by mistake.
28. Use a compressor and an air hose intended for
high-pressure nailers.
This nailer is designed to operate with air pressure
higher than that for general nailers. Therefore, use a
compressor and an air hose intended for use with a
high-pressure nailer. The main unit of this nailer, its air
plug, and the air socket used to connect the compressor
and air hose are exclusively designed for use with high-
pressure parts, and cannot be connected to standard-
pressure parts. Do not modify the air plug and air
socket. Using other parts may result in an accident.
