ABOUT WORK AREA
● Keep the work area clean.
Cluttered work areas (e.g. workbench) invite
accidents.
● Carefully select the work area.
Do not expose tool to rain.
Do not use tool in a wet or soaked area.
See that the work area is adequately illuminated.
● Never work near inflammable liquid or in a
potentially explosive atmosphere.
● Keep children away from the work area.
Keep children and unauthorized people away from
the work area to avoid accident or injury.
BEFORE OPERATION
● Inspect tool before use.
Before using, check that screws are securely
tightened, that any protective cover or guard is
securely in place, other parts are free from damage
and that the tool runs as it should.
Check that moving parts are properly adjusted for
positioning and tightened, that parts are free from
damage and properly mounted, and that all other
parts are in good condition for normal operation.
Should you find any damage to the protective
cover or other part, replace it in accordance with
the Operation Manual. If there are no instructions
in the Manual, please contact the sales agent
through which you have purchased your tool or an
authorized dealer near you for repair.
Likewise, if a switch failure occurs, contact sales
agent through which you have purchased your tool
or an authorized dealer near you for repair. .
Do not use the tool if it does not start or stop with
the start/stop switch.
● Securely mount cutter
An improperly mounted cutter may fly out, causing
possible damage to the tool or injury to the operator.
● Always remove spanner, wrench, etc., once
adjustment has been made with them.
● Use a tool appropriate for the application.
Avoid heavy-duty application that is beyond the
capacity of tool.
● Do not use the tool for purposes other than what
it is designed for.
● Do not abuse tool.
Use tool in accordance with the specifications: you’ll
get the most out of it while ensuring safety.
● Securely fasten workpiece in place.
Use a vice or clamp to securely fasten the workpiece
in place. It is much safer this way than holding it in
your hand, allowing you to operate the tool with both
hands.
ABOUT HANDLING
● How to store tool.
When the tool is not used, store it in a dry area and
out of reach of children.
● How to carry tool.

power source. Do not leave the work area until the
tool comes to a complete stop.
MAINTENANCE/SERVICE
● Do not take apart or modify tool.
Disassembly or modification carried out without
the supervision of a qualified or authorized service
engineer could result in an accident or injury.
● Inspect cutting tool and accessories, etc.
Always check to see that cut t ing too l and
accessories, etc. are in good operating condition
without damage or deterioration before you mount
them on the tool. Should you find any damage to
an accessory or part, please contact sales agent
through which you have purchased your tool or an
authorized dealer near you for repair.
● Check parts for damage.
When you have found damage to accessory or other
part, carefully check the damaged part to determine
the extent of influence it has upon the functions
of the tool – that is, determine whether it can still
perform its normal functions.
Check to see that the linkage of the moving parts
is OK, that all parts are OK without damage,
that they are properly mounted, and that the tool
functions normally. Should you find any damage
to an accessory or part that may hamper proper
functioning of the tool, please contact sales agent
through which you have purchased your tool or an
authorized dealer near you for repair.
● Have your tool repaired at an authorized Nitto
Service Center.
For repair or parts replacement, please contact the
sales agent through which you have purchased your
tool or an authorized dealer near you.
● Use only Nitto genuine parts.
Use of improper parts may result in serious accident.
To obtain a Nitto genuine part, consult this Manual
or contact the sales agent from which you have
purchased your tool directly.
● Do not detach label or nameplate from tool.
When a label/nameplate gets damaged, worn or
becomes missing, contact the sales agent through
which you have purchased your tool or Nitto Kohki
Co. Ltd, directly for a replacement.
DISPOSAL
● When a tool is taken permanently out of service, it
is advised that the tool is disassembled, degreased
and parts separated by material and recycled locally
in the appropriate manner.
GENERAL: PNEUMATIC
TOOLS
WARNING
● Use appropriate air pressure.
Excessively high air pressure will increase the tool
number of revolutions or strokes causing not only
potential premature failure/breakage but could also
lead to an unexpected accident or injury.
● Connect tool to air supply line.
There are various types of pipes running in a factory
in addition to the pneumatic line (such as oxygen,
nitrogen, gas and water). For this reason, always
ensure that you are connecting to the pneumatic
line.
● Start tool properly.
Turn the start switch OFF before connecting to the
air supply line.
● Always disconnect the tool from the air supply
line before putting on/taking off any accessory
and prior to carrying out any maintenance work.
● Avoid exposure to exhaust air.
Pneumatic tool exhaust air contains oi l and
contaminated moisture. Make sure the exhaust air is
not directed towards your face or anyone else within
the work area.
● Keep tool off electricity.
This pneumatic tool is not electrically insulated. To
avoid a potential electric shock do not use where
there is a possibility of coming into contact with live
electricity.
CAUTION
● Handle tool carefully.
Abusive use of tool could invite failure or accident.
Do not throw, drop or shock the tool.
● Handle air hose carefully.
Do not carry the tool by the air hose.
Do not pull the air hose to disconnect.

8. STORAGE
CAUTION
When tool is not used, store it out of reach of
children.
Avoid storing the tool in a location subject to high
humidity. If the tool is left as it is used, residual
moisture on the inside can cause rusting. Before
storing, and after operation, oil the tool at the air inlet
with machine oil ISO VG-10 and run it for a short time.
In order to protect the Indexable Insert, place the
Protective Cap on the Disk. Also, by placing the
Gauge to the Protective Cap, you can prevent its loss.
