Attaching Sanding Material; Dust Extraction - Festool DTS 400 Q Notice D'utilisation D'origine

3 Power supply and start-up
The mains voltage must correspond to
the specifi cation on the rating plate.
Always switch the machine off before
connecting or disconnecting the mains
lead!
See Fig. 3 for connection and disconnection of the
power cable.
Switch (1.1) serves as an On/Off switch (I = On/0
= Off).
4 Electronics
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 con-
cerned (see Chapter 6).
The speed is set using the rotary control button
(2.1).
5 Machine settings
Always remove the power supply plug
from the socket before carrying out any
work on the machine.
5.1

Dust extraction

Always connect the machine to a dust
extractor. Dust extractors prevent large
accumulations of dust in
the air in the working environment and dirt col-
lecting at the workplace. Sanding dust is extracted
through the extraction channels in the sanding
pad directly to the material removal point.
a) Inboard extraction
The machines are fi tted with inboard extraction as
standard. The sanding dust is extracted through
suction openings in the sanding base (1.8) 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 extraction power diminishes.
Inserting a turbo-fi lter
- Push the front cardboard section of the turbo-
fi lter with the sealing lip (2.3) onto the extraction
nozzle (2.2) of the fi lter holder
- Insert rear cardboard section with slot (2.4) onto
the retaining strip (2.5) of the fi lter holder
- Push the fi lter holder with its opening (1.3) as
far as it will go onto the extraction nozzle (1.2)
of the machine and clamp tight by turning rotary
knob (1.4).
b) 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 inboard extraction. In this case,
the extraction pipe (Ø 27 mm (1.6)) of the extrac-
tion unit is connected to the suction nozzle (1.2).

Attaching sanding material

Always use original Festool sanding ma-
terials!
Self-adhesive abrasives such as Stickfi x sand-
paper and sanding fl eeces can be attached to
Stickfi x sanding shoes. The abrasives (1.7) are
simply pressed onto the sanding shoe (1.8) and
pulled off after use.
6 lnstructions on application
Never overload the tool by using too much pres-
sure!
The best sanding results are achieved when ap-
plying moderate pressure.
The sanding performance and quality depend
mainly on the choice of the right sanding mate-
rial.
We recommend the following settings on the ro-
tary control (2.1) for electronic tools:
Rotary control setting
- sanding work
5 - 6
- sanding with max. drive
- sanding old paint
- sanding wood and veneer prior to painting
- interim sanding of paint on surfaces
4 - 5
- sanding of thinly applied primer
- sanding of wood with sanding vlies
- sanding edges on wooden parts
- smoothing primed wooden surfaces.
3 - 4
- sanding full wooden and veneer edges
- sanding in the grooves/rebates of windows and
doors
- interim paint sanding on edges
- pre-sanding natural wood windows with sanding
vlies
- smoothing wood surfaces with sanding felt prior
