with this power tool. Failure to follow all instruc-
tions listed below may result in electric shock, fi re
and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR
FUTURE REFERENCE.
The term "power tool" in the warnings refers to
your mains-operated (corded) power tool or batteryoperated (cordless) power tool.
General safety instructions
1) Work area safety
a) Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
b) Do not operate power tools in explosive atmo-
spheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create
sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while op-
erating a power tool. Distractions can cause you
to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodifi ed plugs and matching outlets
will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase
the risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk
of electric shock.
f) If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the infl uence of drugs, alcohol or medi-

cation. A moment of inattention while operating power tools may result in serious personal
injury.
b) Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool. Carrying power tools
with your fi nger on the switch or energising
power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool
may result in personal injury.
e) Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of
the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away
from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
dust collection can reduce dust-related hazards.
h) Do not let familiarity gained from frequent use
of tools allow you to become complacent and
ignore, tool safety principles. A careless action
can cause severe injury within a fraction of a
second.
4) Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and
must be repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing accessories, or storing power tools. Such preven-
tive safety measures reduce the risk of starting
the power tool accidentally.
d) Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in
the hands of untrained users.
e) Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits
etc. in accordance with these instructions, taking into account the working conditions and the
work to be performed. Use of the power tool for
operations different from those intended could
result in a hazardous situation.
h) Keep handles dry, clean and free from oil and
grease. Slippery handles do not allow for safe
handling and control of the tool in unexpected
situations.
5) Service
a) Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the
power tool is maintained.
General safety instructions for sanding
a) This power tool is intended to function as a
sander. Read all safety warnings, instructions,
illustrations and specifi cations provided with
this power tool. Failure to follow all instructions
listed below may result in electric shock, fi re
and/or serious injury.
b) Operations such as grinding, polishing, wire
brushing or cutting-off are not recommended to
be performed with this power tool. Operations
for which the power tool was not designed may
create a hazard and cause personal injury.
c) Do not use accessories which are not specifi -
cally designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
d) The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and fl y apart.
e) The outside diameter and the thickness of ac-
cessories must be within the capacity rating of
5
your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
f) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by fl anges, the arbour hole of the
accessory must fit the locating diameter of
the fl ange. Accessories that do not match the
mounting hardware of the power tool will run
out of balance, vibrate excessively and may cause
loss of control.
g) Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install
an undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damaged ac-
cessories will normally break apart during this
test time.
h) Wear personal protective equipment. De-
pending on application, use face shield, safety
goggles or safety glasses. As appropriate, wear
dust mask, hearing protectors, gloves and shop
apron capable of stopping small abrasive or
workpiece fragments. The eye protection must
be capable of stopping fl ying debris generated by
various operations . The dust mask or respirator
must be capable of fi ltrating particles generated
by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
i) Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Frag-
ments of workpiece or of a broken accessory
may fl y away and cause injury beyond immediate
area of operation.
j) Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
k) Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled
into the spinning accessory.
l) Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the
power tool out of your control.
m) Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
n) Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
o) Do not operate the power tool near fl ammable
materials. Sparks could ignite these materials.
p) Do not use accessories that require liquid cool-
ants. Using water or other liquid coolants may
result in electrocution or shock.
Further safety instructions for all operations
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or
any other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in turn
causes the uncontrolled power tool to be forced in
the direction opposite of the accessory’s rotation at
the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into
the surface of the material causing the wheel to
climb out or kick out. The wheel may either jump
toward or away from the operator, depending on
direction of the wheel’s movement at the point of
pinching. Abrasive wheels may also break under
these conditions.
Kickback is the result of power tool misuse and/
or incorrect operating procedures or conditions
and can be avoided by taking proper precautions
as given below.
a) Maintain a fi rm grip on the power tool and po-
sition your body and arm to allow you to resist
kickback forces. Always use auxiliary handle,
if provided, for maximum control over kickback
or torque reaction during start-up. The operator
can control torque reactions or kickback forces,
if proper precautions are taken.
b) Never place your hand near the rotating acces-
sory. Accessory may kickback over your hand.
c) Do not position your body in the area where
power tool will move if kickback occurs. Kick-
6
back will propel the tool in direction opposite to
the wheel’s movement at the point of snagging.
d) Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory
and cause loss of control or kickback.
e) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control.
Safety Warnings Specif-
ic for Sanding Operations
a) Do not use excessively oversized sanding disc
paper. Follow manufacturers recommendations, when selecting sanding paper. Larger
sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
snagging, tearing of the disc or kickback.
TO REDUCE THE RISK OF INJURY,
USER MUST READ INSTRUCTION MANUAL.
Various dust created by power sanding,
sawing, grinding, drilling and other construction
activities contains chemicals known (to the State
of California) to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and
other masonry products,
• Arsenic and chromium from chemically-treated
lumber.
The risk from these exposures varies, depending
on how often you do this type of work.
To reduce your exposure to these
chemicals work in a well ventilated
area and use approved safety equipment, such as dust masks that are specially designed to fi lter out microscopic
particles.

Intended use
The RAS 115 E is designed for sanding wood, plastics, stone, composite materials, paints / lacquers,
fi llers, stoppers and similar materials.
Never use the tool for grinding or cutting metal. Materials containing asbestos must not
be processed.
Never fasten grinding disks on the
tool. Work only with the provided sanding pad and
whereupon fastened abrasives.
The device is unsuitable for wet sanding for reasons of electrical safety.
7
If explosive or self-infl ammable dusts are produced
when sanding certain materials, refer to the processing instructions of the material manufacturer.
The user bears sole responsibility for
any damage or accidents resulting from incorrect
use.
Electrical connection and operation
The mains voltage must correspond
to the voltage on the rating plate!
1.1
To switch the tool on, push the safety sliding switch
(1.1) forwards. The tool is switched off by gently
pressing the rear end of the switch.
Extension cord
If an extension cord is required, it must have suffi cient cross-section to prevent an excessive drop
in voltage or overheating. An excessive drop in voltage reduces the output and can lead to failure of
the motor. The table below shows you the correct
cord diameter as a function of the cord length for
the RAS 115 E.
Total Extension Cord
Lenght (feet)
25 50 100 150
Cord size (AWG) 18 16 16 14
Use only U.L. and CSA listed extension cords. Never
use two extension cords together. Instead, use one
long one.
Note: The lower the AWG number, the stronger the
cord.
Electronic control
The tool has full-wave electronics with the following features.
Do not use the rotary sander if the
electronic control is defective, since this can lead
to excessive speeds. A defect of this kind can be
recognized by the fact that the smooth run-up is
absent, the noise level under no-load conditions is
higher or the speed cannot be controlled.
Speed adjustment
2.1
You can regulate the speed steplessly between
1500 and 4000 rpm using the adjusting wheel (2.1).
This lets you optimize the sanding speed to suit the
material (see "Working with the tool").
Smooth start-up
The smooth start-up ensures jolt-free startup.
Constant speed
The pre-selected speed remains constant whether
the tool is in operation or in neutral position.
Temperature control
To prevent overheating, the safety electronics
switch the tool off when it reaches a critical motor
temperature. Let the tool cool down for approx. 3-5
minutes before using it again. The tool requires
less time to cool down if it is running, i.e. in neutral
position.
Tool settings
Always remove the power plug from
the socket before carrying out any work on the
power tool.
Extraction hood AH-RAS D 115
The extraction hood AH-RAS D 115 (3.1) can be used
in conjunction with the sanding pads STF D 115.
3.4
3.2
3.3
3.1
a) Fitting
Before fi tting the extractor hood, ensure that the
clamping lever is in “released” position (3.4). Press
the extractor hood onto the clamping throat (3.2) of
8
the rotary sander and secure the hood by moving
the clamping lever forward (3.3).
4.1
4.2
4.5
4.4
4.3
Do not work with the machine unless the extractor
hood is clamped fi rmly and securely to the clamping throat. If the clamping force is reduced as the
result of frequent use, the clamping lever can be
re-adjusted.
–Release the screw (4.1) on the clamping lever and
remove the lever (4.2).
–Tighten the square-headed screw (4.3) by hand
until a tension is obtained.
–Re-fi t the clamping lever and secure it with the
screw. The optimum clamping force can be determined by closing the clamping lever before the
clamping screw is tightened.
b) Repositioning the rotatable handle
The rotatable additional handle can, if required, also
be fi tted to the right-hand side of the extractor hood.
For this purpose, the handle and the clamping lever
should be interchanged.
–Release the screw (4.1) on the clamping lever and
remove the lever (4.2).
–Remove the square-headed screw (4.3).
–Detach the additional handle (4.5), using a 6 mm
A/F Allen key.
The clamping lever and the additional handle can
now be interchanged. Fitting is carried out in the
reverse of the above sequence. The locking nut
(4.4) can be used to vary the turning resistance of
the rotatable additional handle by tightening the
nut against the housing, using a 13 mm A/F openended wrench, before fully tightening the additional
handle.
c) Replacing the brush insert
5.1
5.2
In order to replace this, press out the brush insert
by inserting a screwdriver through the square apertures (5.1). Insert the new brush strip (5.2) into
the groove, slightly bend this to obtain the correct
radius and press in fi rmly until the brush strip is in
contact with the base of the hood. The inclination of
the brush bristles must point outwards.
Two different brush inserts are available:
• AH-RAS D 115 Poly (484727): Pack of 2 polyamide
brushes (replacement for worn originals)
• AH-RAS D 115 metal (484728): Pack of 1 metal
brush (for use with spark-generating materials)
d) Sanding with dust extraction
For dust extraction, the suction hose (27 mm dia.)
of a Festool dust extractor should be inserted into
the connection socket (6.3) at the end of the rotary
sander housing.
The brush ring (6.2) can be adjusted by means of
the additional rotatable handle (6.1). This makes
it possible to achieve an optimum setting for the
working position used. Always turn the brush ring
into the direction of travel of the sanding dust.
A considerable quantity of air-borne sparks are
generated during the sanding of metals and other
spark-generating materials. For safety reasons,
therefore, a spark-trap (484733) must be fi tted
between the extractor hood and the rotary sander.
6.3 6.1 6.2
Fitting tool inserts
Use only tool inserts whose maximum
permissible speed is at least equal to the speed
given on the rating plate of the rotary sander. This
is the case with all original Festool accessories.
The Stickfi x sanding pads STF D 115 are provided
with an M 14 thread which enables these to be
screwed directly onto the drive spindle.
It is normally possible to unscrew the sanding pad
(7.3) by hand from the drive spindle after pressing
the spindle stop (7.1).
Actuate the spindle stop only when the
drive spindle is stationary. Do not switch on the motor when the spindle stop is pressed in.

7.1
7.2
7.3
7.4
In case the pad should seize:
– Remove the brush insert.
– Insert the special spanner (7.4) through the slot
(7.2) and place on spanner fl ats of tool.
– Release the tool with the spindle stop pressed by
turning the special spanner.
Please note: Always screw the sanding pad onto the
drive spindle by hand. This will make it considerably
easier to remove it subsequently.
Attaching the abrasive
Stickfi x is a hook-and-loop fastening sys-
tem. Stickfi x sanding pads allow the use
of self-adhesive hook-and-loop abrasives
such as Stickfi x sandpapers and sanding
cloths.
Simply press the abrasive onto the sanding pad and
pull it off again after use.
Use only abrasives with an undamaged
Stickfi x hook-and-loop coating. Before use, check
that the coating has not been damaged by improper
use (such as over heating).
In the case of a weakening adhesive
effect of the StickFix surface, the sanding pad accessories, in particular those which are not yet
touching the workpiece, may come loose from
the sanding pad and cause injuries. Replace the
sanding pad!
The Mini-Stickfi x D 52 sanding pad was
developed for use in confi ned spaces and with small
areas. This small-diameter pad and the affi xed
abrasive will inevitably heat up in use more than
larger pads, since the same pressure is distributed
over a smaller area. Sand only with moderate pressure and do not sand continuously for too long. Lift
the sander off the workpiece at intervals to allow
friction heat to dissipate.
Working with the tool
Always secure the workpiece in such
a manner that it cannot move while being sanded.
Never overload the tool by using too
much pressure! The best sanding results are
achieved when applying moderate pressure. Sanding performance and quality depend primarily on
the choice of the right abrasive.
For safe guidance, always hold the tool
with both hands.
We recommend the following settings on the rotary
control (2.1) for electronic machines:
6
• Sanding hard GRP components (limited suit-
ability).
3 - 6
• Sanding off dry, cracked paint.
• Stripping anti-fouling paints.
• Sanding wood.
2 - 4
• Sanding paint/varnish with tendency to smear
• Light sanding of thin top coats of paint.
• Cleaning sandstone, concrete, formwork materi-
als.
1 - 2
• Sanding thermoplastic materials.
Maintenance and care
All maintenance or repair work requiring the motor housing to be opened must be carried
out only by an authorized service workshop. Maintenance or repair work carried out by an unauthorized
person can lead to the incorrect connection of the
wiring or other components, which in turn can lead
to accidents with serious consequences.
Always remove the plug from the
mains supply socket before carrying out any work
on the machine!
Always keep the tool and in particular the ventilation slots clean.
The tool is fi tted with special motor brushes with
an automatic cut-out. When the brushes become
worn the power supply is shut off automatically and
the tool comes to a standstill.
