Electrical connec-
tion and operation
The mains voltage must correspond with the volt-
age on the rating plate!
See the following fi gure for connection and dis-
connection of the power cable.
Always switch the machine off before
connecting or disconnecting the power cable!
Switch (2.1) is an on/off switch. For continuous
use it can be engaged with the lateral locking
button (2.2). Pressing the switch again releases
the lock.

Extension cord
If an extension cord is required, it must have suf-
fi 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 cor-
rect cord diameter as a function of the cord length
for the ETS 150/3 EQ, ETS 150/5 EQ.
Total Extension Cord

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.
Tool settings
Always remove the power plug from
the socket before carrying out any work on the
power tool.
Electronic control
You can regulate the speed steplessly between
6000 and 10500 rpm using the adjusting wheel
(2.3). This lets you optimize the sanding speed to
suit the material (see "Working with the tool").
Dust extraction
Dust extractors prevent large accumulations of
dust in the air in the working environment and
dirt collecting in the workplace.
Inboard extraction
3.33.23.1
3.4 3.5 3.6 3.7 3.8 3.9
The machines are fi tted with inbuilt extraction as
standard. The sanding dust is extracted through
suction openings in the sanding base (3.4) and
trapped in the turbo-fi lter (3.2).
The turbo-fi lter has to be changed when it is so full
of dust that the extraction power diminishes:
– Push the front cardboard section of the turbo-
fi lter with the sealing lip (3.1) onto the extraction
nozzle (3.8) of the fi lter holder
– Insert rear cardboard section with slot (3.3) onto
the retaining strip (3.9) of the fi lter holder
– Push the fi lter holder with its opening (3.6) as
far as it will go onto the extraction nozzle (3.5)
of the machine and clamp tight by turning rotary
knob (3.7).
External extraction by an extraction unit
4.1
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) (4.1)
of the extraction unit is connected to the suction
nozzle.
