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 suffi cient
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.

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.
Please make sure that the air pressure is within a range
of 12 bar – 23 bar (170 ~ 320 psi.), and that the air which
is used is clean and dry. If the air pressure is greater
than 23 bar (320 psi.), the life of the power tool will be
shortened and dangerous conditions could develop.
Tools shall not be connected to pressure which
potentially exceeds 26 bar (370 psi.).
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. Be careful of ignition and explosions.
Since sparks may fl y during nailing, it is dangerous
to use this tool near lacquer, paint, benzine, thinner,
gasoline, gas, adhesives and similar infl ammable
substances as they may ignite or explode. Under no
circumstances should this tool therefore be used in the
vicinity of such infl ammable material.
5. Always wear eye protection (protective goggles).
When operating the power tool, always wear eye
protection, and ensure that surrounding people wear
eye protection too.
The possibility of fragments of the wire or plastic linking
the nails or nails that were not properly hit entering the
eye is a threat to sight. Eye protection can be bought at
any hardware store. Always wear eye protection while
operating this tool. Use either eye protection or a wide
vision mask over prescription glasses.
Employers should always enforce the use of eye
protection equipment.
6. Protect your ears and head.
When engaged in nailing work please wear ear muffl ers
and head protection. Also, depending on condition,
ensure that surrounding people also wear ear muffl ers
and head protection.
7. Pay attention to those working close to you.
It would be very dangerous if nails that were not properly
driven in should hit other people. Therefore, always pay
attention to the safety of the people around you when
using this tool. Always make sure that nobody's body,
hands or feet are close to the nail outlet.
8. Never point the nail outlet towards people.
Always assume the tool contains fasteners.
If the nail outlet is pointed towards people, serious
accidents may be caused if you mistakenly discharge
the tool. When connecting and disconnecting the
hose, during nail loading or similar operations, be
sure the nail outlet is not pointed towards anyone
(including yourself). Even when no nails are loaded at
all, it is dangerous to discharge the tool while pointing
it at someone, so never attempt to do so. No horseplay.
Respect the tool as a working implement.
9. Before using the power tool, check the push lever.
Before using the power tool make sure to check that the
push lever and valve operate properly. Without nails
loaded into the power tool, connect the hose and check
the following. If the sound of operation occurs this
indicates a fault, so in such a case do not use the power
tool until it has been inspected and repaired.
○ If merely pulling the trigger causes operating sound
of drive bit movement occur, the power tool is faulty.
