tions. Failure to follow all instructions listed below
may result in electric shock, fi re and/or serious
personal injury.
SAVE THESE INSTRUCTIONS
General safety rules
1) Work area safety
a) Keep work area clean and well lit. Cluttered
and dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, 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
operating 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 electric shock if your body is earthed or
grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will in-
crease 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) Hold power tool by insulated gripping surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Contact with a
„live“ wire will make exposed metal parts of the
power tool „live“ and shock the operator.
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 medication. A moment of inattention while
operating power tools may result in serious personal injury.
b) Use safety equipment. Always wear eye
protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce
personal injuries.
c) Avoid accidental starting. Ensure the
switch is in the off position before plugging
in. Carrying power tools with your fi nger on the
switch or plugging in 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
balance 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, clothing
and gloves 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 these devices can reduce dust re-
lated hazards.
4) Tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The cor-
rect 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
2
cannot be controlled with the switch is dangerous
and must be repaired.
c) Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing power tools.
Such preventive safety measures reduce the risk
of starting the power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are dan-
gerous 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 tools 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 and in the manner intended for the
particular type of power tool, 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.
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.
• 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 micro-
scopic particles.

Specifi c Safety Rules
a) Hold power tools by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Contact with a
„live“ wire will make exposed metal parts of the
power tool „live“ and shock the operator.
TO REDUCE THE RISK OF INJURY,
USER MUST READ AND UNDERSTAND 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,
Intended use
The RAS 115.04 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.
If explosive or self-infl ammable dusts are pro-
duced 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 connec-
tion and operation
The mains voltage must correspond
to the voltage on the rating plate!
To switch the tool on, push the safety sliding
switch (1.1) forwards. The tool is switched off by
gently press-ing the rear end of the switch.
1.1
(2.1). This lets you optimize the sanding speed to
suit the material (see "Working with the tool").
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
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 115.04 E.
Total Extension Cord
Lenght (feed)
Cord size (AWG)18161614
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.
2550100150
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.
Smooth start-up
The smooth start-up ensures jolt-free startup.
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.
3.2
3.3
3.4
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 the rotary sander and secure the hood by moving the clamping lever forward (3.3).
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.
Speed adjustment
2.1
You can regulate the speed steplessly between
1500 and 4000 rpm using the adjusting wheel
4.3
4.2

4.4
4.5
– 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 extrac-
tor 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
open-ended wrench, before fully tightening the
additional handle.
c) Replacing the brush insert
5.1
5.2
6.36.16.2
The brush ring (6.2) can be adjusted by means of
the additional rotatable handle (6.1). This makes
it possi-ble to achieve an optimum setting for
the working position used. Always turn the brush
ring into the direc-tion 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.
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.
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 origi-nals)
• 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.
7.1
7.4
7.2
7.3
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
Maintenance and care
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).
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 dissi-pate.
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 ro-
tary control (2.1) for electronic machines:
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.
Accessories, tools
For safety reasons, only use original
Festool accessories and tools!
The accessory and tool order number can be found
in the Festool catalog or on the Internet under
www.festool-usa.com.
Systainer
Many Festool products are shipped in a unique
system container, called "Systainer". This provides
protection and storage for the tool and accessories. The Systainers are stackable and can be
interlocked together. They also can be interlocked
atop Festool CT dust extractors.
