Hitachi NR90GC2 Handling Instructions Manual page 45

Keep the firing 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 finger on the trigger.
Do not place your finger on the trigger except when
actually nailing. If you carry this tool or hand it to
someone while having your finger on the trigger,
you may inadvertently discharge a nail and thus
cause an accident.
13. Press the nail outlet firmly against the material to
be nailed.
When driving in nails, press the nail outlet firmly
against the material to be nailed. If the outlet is not
applied properly, the nails may rebound.
14. Keep hands and feet away from the firing head
when using.
It is very dangerous for a nail to hit
the hands or feet by mistake.
15. Do not touch around the exhaust outlet.
This tool produces hot exhaust gases
that may flammable materials. The
push lever and nose will become hot
and get heated up after prolonged or
rapid use.
Do not touch with bare hands.
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 scaffoldings, ladders.
The power tool shall not be used for specific
application for example:
– when changing one driving location to another
involves the use of scaffoldings, stairs, ladders or
ladder alike constructions, e.g. roof laths,
– closing boxes or crates,
– fitting transportation safety systems e.g. on
vehicles and wagons
20. Disconnect the battery and fuel cell and take out
any nails left in the magazine after use.
Disconnect the battery and fuel cell from the tool
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 fired by mistake.
21. When removing a nail which has become stuck,
make sure to first of all disconnect the battery and
fuel cell.
When removing a nail which has become stuck in
the nail outlet, first of all make sure to disconnect
the battery and fuel cell inside the power tool.
Accidental firing of the nail could be very dangerous.
22. The operating environment for this device is
between 0°C and 40°C so ensure use within this
temperature range. The device may fail to operate
below 0°C or above 40°C.
23. Always charge the battery at an ambient
temperature of 0–40°C.
A temperature of less than 0°C will result in over
charging which is dangerous. The battery cannot
be charged at a temperature greater than 40°C.
The most suitable temperature for charging is that

If the battery is burnt, it may explode.
29. Using an exhausted battery will damage the
charger.
30. Bring the battery to the shop from which it was

becomes too short for practical use.
Do not dispose of the exhausted battery.
31. Do not insert objects into the air ventilation slots
of the charger.
Inserting metal objects or flammable into the
charger air ventilation slots will result in an electrical
shock hazard or damage to the charger.
32. Do not inhale its contents.
In case of being inhaled ; the person
affected should be taken into the
open air and brought into a
comfortable position.
33. Expanding gases cause low temperatures.
Fluid gases might cause injuries when getting in
touch with skin or eyes.
