GENERAL OPERATIONAL PRECAUTIONS
1. Operate the power tool safely for correct uses.
Do not use the power tool for uses other than those
specified in this instructions.
2. For safe operation handle the power tool correctly.
Please follow the instructions given in this instruction
manual and correctly handle this tool so as to ensure
safe operation. Never let the tool be use by children
or people who do not know enough to be able to
handle it correctly, or let it be used by people who
cannot operate it correctly.
3. Confirm the safety of the workshop.
Keep unauthorized people away from the workshop.
Especially children should be kept away.
4. The right parts in the right places.
Do not remove any of the covers or screws. Keep
them in place as they have their functions.
Moreover, because it would be dangerous, never
make modifications to the tool or use it after making
modifications.
5. Check the tool before using it.
Before using the tool, always check that no parts of it
are broken, that all screws are completely tight, and
that no parts are missing or rusty.
6. Excessive work could cause accidents.
Do not make tools and accessories work beyond
their abilities. Excessive work not only damages the
power tool but also is dangerous in itself.
7. Stop operation immediately if abnormalities are
noticed.
Stop operation if you notice abnormalities, or if the
power tool does not work properly; have the power
tool inspected and serviced.
8. Look after the power tool carefully.
If you drop or knock the power tool against things,
the outer frame may be deformed and cracks or
other kinds of damage may occur, so please handle it
with sufficient care. Also, do not scratch or engrave
signs on the power tool. Owing to high pressure air
inside the tool, cracks in the surface are dangerous.
Never use the power tool if a crack develops or if air
is escaping from a crack.
9. Take good care for a long life.
Always take good care of the power tool and keep it
clean.
10. Inspection at regular intervals is essential for safety.
Inspect the power tool at regular intervals so that the
power tool can be operated safety and efficiently at
all times.
11. Consult an authorized service agent if repair or parts
replacement is necessary.
Ensure that the power tool is serviced by authorized
service agent only, and that only genuine replacement
parts are used.
12. Keep the power tool in a proper place.
When not in use, the power tool should be kept in a
dry place out of the reach of children. Put into the
body 5-10 drops oil through the hose joint to protect
the tool from rust.
13. The exploded assembly drawing on this handling
instructions should be used only for authorized
service center.

PRECAUTIONS ON USING NAILER
1. Safe operation through correct usage
This tool was designed for driving nails into wood
and similar materials. Use it for its intended purpose
only.
2. Make sure air pressure is within the rated range of
air pressure.
Fastener driving tools operated by compressed air
shall only be connected to compressed air lines where
the maximum allowable pressure cannot be exceeded
by a factor of more than 10% which can for example
be achieved by a pressure reduction valve which
includes a downstream safety valve.
(For model NR50AK, 110% of rated maximum
allowable pressure is 9.1 bar = 130 psi)
Fastener driving tools operated by compressed air
should only be operated at the lowest pressure
required for the work process at hand, in order to
prevent unnecessarily high noise levels, increased
wear and resulting failures.
3. Never operate the equipment with high-pressure
gases other than compressed air.
Never use carbon dioxide, oxygen or another gas
from pressurized containers under any circumstances.
4. Never drive nails into metal or concrete.
YES
• pre-punched holed
metal
• wood
If the nail is driven into metal or concrete directly, it
could ricochet and hurt yourself as well as others.
5. Always be aware of position of firing head.
YES
work surface
When the firing head is pointed away from work
surface, injuries can occur.
6. Keep the tool aligned with the pre-punched metal
hole when firing.
