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.

SAFETY RULES

  

1.

Always assume that the tool contains fasteners.

  

2.

Do not point the tool towards yourself or anyone
else, whether it contains fasteners or not.

  

3.

Never depress the operating mechanism or work-
contacting element unless the nose of the tool is
directed onto a safe work surface or test material.

  

4.

Never horseplay or skylark with any tool.

  

5.

Never trigger the tool when moving it from fixing
to fixing.

  

6.

Do not load the tool with fasteners while any part of
the operating mechanism is depressed.

  

7.

Always take extra care when nailing near to the edge
of material and when skew nailing.

  

8.

Never use volatile or combustible gas to power a
pneumatic tool, that is a tool designed to be powered
with compressed air.  Never use bottled oxygen.

  

9.

Always disconnect the tool when it is left
unattended.  If a suitable stand is available, the tool
should be left in that.

  

10. Always disconnect the tool before carrying out

cleaning or adjustment.

  

11. Never use a defective tool.

  

12. Always have a competent experienced person carry

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 4.9 bar – 8.3 bar (70 ~ 120 psi.), and that
the air which is used is clean and dry. If the air
pressure is greater than 8.3 bar (120 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 14
bar (200 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 fly during nailing, it is dangerous
to use this tool near lacquer, paint, benzine, thinner,
gasoline, gas, adhesives and similar inflammable
substances as they may ignite or explode. Under
no circumstances should this tool therefore be used
in the vicinity of such inflammable 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 nails that were
not properly hit entering the eye is a threat to sight.
