4 Electrical connection and operation
WARNING
Risk of accident if the machine is operated using
unauthorised voltages or frequencies.
- The mains voltage and the frequency of the
power source must correspond with the speci-
fi cations on the machine’s name plate.
- In North America, only Festool machines with
voltage specifi cations of 120 V may be used.
Switch (1.2) is an on/off switch. For continuous
use it can be engaged with the lateral locking
button (1.3). Pressing the switch again releases
the lock. Only ETS 150/3 EQ, ETS 150/5 EQ: See
Fig. 3 for connection and disconnection of the
power cable.
5 Electronic control
The ETS 150/3 EQ, ETS 150/3 E, ETS 150/5
EQ, ETS 150/5 E has an electronic control
with which the rotational speed can be
varied step-free.
This allows the sanding speed to be adapted to
the optimum level according to the material con-
cerned (see Chapter 9). The speed is set using the
rotary control button (1.1).
6 Dust extraction
CAUTION
Dust may be harmful or cause allergic reac-
tions!
• Always connect the machine to a dust extractor.
• When performing work that generates dust,
always wear a dust mask.
6.1 Turbo-fi lter (partly accessories)
The sanding dust is extracted through suction
openings in the sanding base (1.13) and trapped
in the turbo-fi lter (1.5).The turbo-fi lter has to be
changed when it is so full of dust that the extrac-
tion power diminishes.
Inserting a turbo-fi lter
- Push the front cardboard section of the turbo-
fi lter with the sealing lip (1.4) onto the extraction
nozzle (1.9) of the fi lter holder
- Insert rear cardboard section with slot (1.6) onto
the retaining strip (1.7) of the fi lter holder
- Push the fi lter holder with its opening (1.11) as
far as it will go onto the extraction nozzle (1.12)
of the machine and clamp tight by turning rotary
knob (1.10).
6.2 External extraction by an extraction unit
In order to avoid frequent changing of the turbo-
fi lter when carrying longer sanding jobs, it is
possible to connect a Festool extractor to the unit
instead of using inbuilt extraction.
In this case, the extraction pipe (Ø 27 mm (1.8))
of the extraction unit is connected to the suction
nozzle (1.12).
7 Choice and installation of the sanding
disks
7.1 Choice of sanding disk
The appliance can be fi tted with three sanding
disks of different hardness depending on the
surface to be treated.
Hard: coarse sanding on surfaces, sanding at
edges.
Soft: universal for coarse and fi ne sanding, for
fl at and curved surfaces.
Super-soft: fi ne sanding on formed parts, curves,
radii. Do not use on edges!
7.2 Assembly
The sanding disks and the tool-holding fi xture on
the appliance are equipped with a positive holder
(2.1).
CAUTION
Risk of injury
• Make sure the sanding disk is correctly posi-
tioned before screwing it tight.
• For safety reasons, only use original Festool
sanding disks!
8 Attaching sanding material
Always use original Festool sanding materials!
The appropriate Stickfi x sanding paper and Stick-
fi x sanding felt can be fastened quickly and easily
onto the Stickfi x sanding base. The self-adhesive
sanding material (1.14) is simply pressed onto
the sanding base (1.13) and held safely in place
by the Stickfi x sanding base velcro surface. After
use, the StickFix sandpaper is simply pulled off.
9 Operating instructions
Never overload the tool by using too
much pressure!
The best sanding results are achieved when ap-
plying moderate pressure. The ETS 150/3 EQ,
ETS 150/3 E gives the best surface quality and
low abrasion. The ETS 150/5 EQ, ETS 150/5 E
provides high abrasion with good surface qual-
