Electrical connec-
tion and operation
The mains voltage must correspond with the
voltage on the rating plate!
See the following Fig. for connecting or dis-
connecting the power cord of the tool.
Always switch the machine off
before connecting or disconnecting the power
cable!
The switch (1.1) acts as an ON / OFF switch
(I = ON / 0 = OFF).

Electronic control
ELECTRONIC
The DTS 400 EQ 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
concerned (see "Working with the tool").
The speed is set using the rotary control but-
ton (2.1).

Dust extraction
Dust extractors prevent large accumulations
of dust in the air in the working environment
and dirt collecting in the workplace.
Inboard extraction

3.5
The machines are fi tted with inbuilt extraction
as standard. The sanding dust is extracted
through suction openings in the sanding base
(3.5) and trapped in the turbo-fi lter (3.4).
The turbo-fi lter has to be changed when it
is so full of dust that the extraction power
diminishes.
Inserting a turbo-fi lter
Push the fi lter holder with its opening (3.2)
as far as it will go onto the extraction nozzle
(3.1) of the machine and clamp tight by
turning rotary knob (3.3).
Push the front cardboard section of the
turbo-fi lter with the sealing lip (3.7) onto
the extraction nozzle (3.6) of the fi lter
holder.
Insert rear cardboard section with slot (3.9)
onto the retaining strip (3.8) of the fi lter
holder.
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.
