Machine-related safety instruc-
tions
- The manufacturer’s handling and processing
instructions must be observed without fail if
explosive or self-igniting dusts are likely to oc-
cur during sanding.
- If dust dangerous to health is produced during
sanding, the machine should be connected to
an appropriate extraction device and the safety
regulations that apply to the working material
should be observed.
- The operating pressure should not exceed 6.5 bar.
- The machine should only be operated with sand-
paper. Grinding wheels and parting grinder discs
are not permitted.
- Onlyworkwithcorrectlyprocessedcompressedair.
Using the Festool service unit VE guarantees this.
- Only use original Festool accessories.
- Wear suitable protection such as ear protection,
safety goggles, a dust mask for work which gen-
erates dust, and protective gloves when working
with raw materials and when changing tools.
- The permissible rotational speed of the acces-
sory must be at least as high as the maximum
speed specified on the machine. Accessories
that rotate faster than the permissible level can
rupture.
- Proceed with caution in unfamiliar surround-
ings that may contain electricity or other supply
cables that harbour hidden dangers. Make sure
that there are no electrical cables, gas pipelines
or similar that, if damaged, could pose a hazard
when the machine is used.
Residual risks
In spite of compliance with all relevant design
regulations, dangers may still present them-
selves when the machine is operated, e.g.:
• Workpiece parts being thrown off,
• Parts of damaged tools being thrown off,
• Noise emission,
• Sawdust emission.

Functional description
Connection and start-up
Make sure that the pneumatic tool
is switched off when you connect the compressed-
air supply.
Compressed-air treatment
The Festool service unit should always be used
to ensure that Festool pneumatic tools function
correctly. Consisting of a filter, control unit, con-
densation drain and lubricator, the service unit
cleans and lubricates the compressed air and
keeps it free of condensation.
For thios tool, the lubricator should be set so that
a drop is applied to the compressed air approx.
every 7-10 minutes.
Damage that occurs as a result of incorrect
compressed-air treatment is excluded from war-
ranty claims.
We recommend a service unit with a 3/8” con-
nector for up to two Festool pneumatic tools. The
compressor used to supply the compressed air
should supply at 20 cfm and an operating pressure
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 Califor-
nia) to cause cancer, birth defects or other repro-
ductive harm. Some examples of these chemicals
are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and
other masonry products, and
• 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
work with approved safety equip-
ment, such as dust masks that are
specially designed to filter out
microscopic particles.

of 87 psi. The diameter of the piping system must
be sufficiently large (at least 9 mm / 1/2”).
IAS 2 hose connector
The eccentric sander is a pneumatic tool for con-
nection to the Festool IAS 2 system.
This hose system combines three functions in
one hose:
- Compressed air supply (1.1)
- Exhaust air extraction (1.2)
- Dust extraction (1.3)

Starting
Pressing the lever (3.1) switches on the pneu-
matic tool. Releasing the lever switches the tool
off again.
Tool settings
Always disconnect the tool from
the compressed air supply before doing any work
on the tool.
Speed adjustment
You can regulate the sanding speed steplessly
between 6,500 and 8,000 rpm using the adjusting
wheel (3.2). This enables you to optimize the speed
to suit the material.
Suction unit
Sanding dust is extracted through the extraction
channels in the sanding pad and taken di-rectly to
the material removal point. To ensure optimized
dust extraction, we recommend using a Festool
dust extractor with automatic switch-on/switch-
off device for compressed-air tools.
In order to prevent damage to the
pneumatic motor, dust extraction must be allowed
to run through the pneumatic tool when it is at
standstill.
Sanding pads
Sanding pads have different weights
depending on their diameter. Using a sanding
pads of the incorrect size will cause excessive
vibration of the tool.
Only use sanding pads with an undamaged burr
layer.
Sanding pads are available in three degrees of
hardness to suit the type of application:
- Hard: high edge strength, for removing coarse
material from surfaces and for sanding edges.
- Soft: universal for coarse and fine sanding, with
elastic structure for even and curved surfaces.
- Super soft: high elasticity, for smooth fine sand-
ing of moulded parts, curves, radii. Do not use
on edges.
Assembly - see Fig. 4. Make sure the positive-fit
supports on the sanding pad (4.1) are flush with
the ones on the tool (4.2).

Abrasive
Self-adhesive abrasives, such as Stickfix sand-
paper, and sanding cloths can be affixed to the
Stickfix sanding pads.
To affix the abrasive, simply press it onto the sand-
ing pad and remove it after use.
The abrasive must be centered on
the pad and the holes aligned with those on the
sanding pad.
Maintenance and care
Always disconnect the tool from
the compressed air supply before doing any work
on the tool.
Any maintenance or repair work requiring the
motor housing to be opened may only be carried
out by an authorized service workshop.
Vanes
We recommend that the vanes on the motor be
replaced after approx. 500 operating hours.
Sanding pad brake
The collar (5.1) makes contact with the sanding
pad, thus preventing uncontrolled vibration of the
sanding pad. This collar wears out over time and
must be replaced should brake fading occur. The
sanding pad must be removed for this. You can
then remove the collar from the snap-on fastener
(5.2) and replace it with a new one.
Lubrication
If the tool has not been used for an extended pe-
riod, such as a weekend, introduce 1 or 2 drops
of lubricating oil into the compressed-air supply
(5.3) on the tool prior to use.
Replacing the silencer
The silencer on the IAS 2 connecting piece must
be replaced at regular intervals to maintain the
power of the pneumatic tool.

Cleaning the extraction channels
We recommend that the extraction channels in the
tool (5.4) be cleaned once a week using a small
pipe-cleaner brush or a cloth (especially when
sanding resin filler).
Accessories, tools
For safety reasons, only use origi-
nal Festool accessories and tools!
