●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 y 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 specications: 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

MAINTENANCE/SERVICE
●Do not take apart or modify tool.
Disassembly or modification carried out without
the supervision of a qualied or authorized service
engineer could result in an accident or injury.
●Inspect cutting tool and accessories, etc.
Always check to see that cutting tool 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 oil 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 connecting hose carefully.
Do not carry the tool by the air hose.
Do not pull the air hose to disconnect.

0.6 MPa.
● Always replace damaged, bent or severely worn
Pads.
Do not use a Pad that has been subjected to an
Abrasive Paper failure.
● Avoid grinding at pad edge or banging pad edge
against work material or other object, as this can
shorten tool life.

3. AIR SUPPLY
3-1. Air Pressure
Adjust air pressure with the air regulator to the
appropriate level for the pneumatic tool used.
Air pressure that is too low will stop the tool from
operating at full capacity.
Air pressure that is too high may cause damage to
the tool.
3-2. Air Line (Fig.1)
Use a 9.5 mm (3/8") I. D. connecting hose between
the compressor and the tool.
Drained water, etc., if flown into the tool, could
cause tool failure. Install an air filter between the
compressor and the tool.

Fig. 1
3-3. Lubrication
Install an oiler between the compressor and the tool.
Use the machine oil ISO VG-10. Failure to lubricate
as required may result in damage to the tool. Use of
oil that is too thick will reduce the performance of the
tool.
4. PREPARATIONS
4-1. Thread Size of Hose Fitting
The product comes with a metal fitting with
Rc(metric) thread. Connect the Bushing R thread x
NPT thread included as standard accessories, if you
would like to have American NPT thread instead.

5. ATTACH ABRASIVE PAPER
WARNING
Always turn off the air supply and disconnect the
air supply hose beforehand whenever replacing
Abrasive Papers.
5-1. Abrasive Paper
Cut standard size paper (9" x 11") into 4 pieces for
Model FS-100C and into 8 pieces for Model FS-50A,
as shown in Fig.2. For dry sanding, use an open
cost type Abrasive Paper with silicon carbide or
aluminum oxide abrasive grains to prevent clogging,
improve grinding efficiency, and prolong the life of
the paper.
Fig.2
Fig. 2
5-2. Attach Abrasive Paper
Raise the circular knob at the end of the Clamp
Spring (2 points), pull to the side, and push it down.
The paper clamp will then open, push in Abrasive
Paper at this point, raise the circular knob and insert
the Clamp Spring inside the Clamp Stopper. This
completes tting the Abrasive Paper. Refer to Fig.3
and Fig.4. Install Abrasive Paper tightly. If both sides
are not clamped completely (Fig.5), cutting and
sanding power will drop. Compare Fig.4 and Fig.5.
Notice how in the incorrectly clamed figure, the
cutting surface of the Abrasive Paper does not come
in contact with the Rubber Pad.
Fig. 3
Fig. 4
Fig. 5
5-3. In Case of Using Double-Sided Adhesive Tape
Attach double-sided adhesive tape to the sponge
part then attach the Abrasive Paper to the tape.
5-4. In Case of Using Spray Adhesive
Spray the Abrasive Paper with adhesive then attach
it to the sponge. Since the Abrasive Paper must
be removed after it has been used. Avoid using
permanent adhesive. Paper adhesives are available.
6. HOW TO OPERATE THE TOOL
6-1. Start and Stop
(1) FS-100C (Fig.6)
To start, press the Trigger until it is locked. Hold the
Trigger in this position. To stop, press the Cancel
Switch and return the Trigger to its original position.
Fig. 6
(2) FS-50A (Fig.7)
To start, push the Trigger all the way towards the
body. To stop, pull the Trigger all the way out away
from the body.Removing
Fig. 7
6-2. Sanding Pressure
Sanding pressure for FS-100C is 20 to 50 N and
for FS-50A is 10 to 30 N. Applying excessive force
will lower sanding efficiency. For flat work, adjust
pressure so force is applied evenly to the entire
surface of the Rubber Pad. Uneven pressure will
result in an irregular surface.
7. REPLACING RUBBER SUPPORTS
WARNING
Always turn off the air supply and disconnect the
air supply hose beforehand whenever replacing
Rubber Supports.
