Switch on/off

The switch [1-1] is an on/off switch (I = ON, 0 =
OFF).
 When the battery is empty, or if there is a power
failure or the mains plug is removed, move the
on/off switch immediately to the Off position.
This prevents uncontrolled restarting.

Mains adapter

WARNING
Unauthorised voltage or frequency!
Risk of accident
The mains voltage and the frequency of the pow-

er source must correspond with the specifica-
tions on the machine's name plate.
In North America, only Festool machines with

the voltage specifications 120 V/60 Hz may be
used.
The mains adapter (available as an accessory de-
pending on the model) facilitates use of the cord-
less sanding technology with mains power, en-
abling you to switch between power supply sources.
The mains adapter enables the mobile dust ex-
tractor's automatic electronic switch-on/shut-off
function.

7.1 Electronics
Smooth start-up
The electronically controlled smooth start-up en-
sures that the machine starts up jolt-free.
Temperature cut-out
To avoid the motor overheating, the power con-
sumption is limited at an excessive motor tempera-
ture. If the temperature continues to rise, the pow-
er tool switches off and can only be switched on
again once the motor has cooled sufficiently.
Constant speed
The preselected motor speed is kept constant
through electronic control. This means that, if the
machine is used as intended (reasonable contact
pressure), a constant sanding speed is achieved.
Setting and adjusting the speed
The speed can be set [1-5] between 6000 and
-1
10000 min using the adjusting wheel.
For sanding, we recommend the following settings
for the adjusting wheel [1-5]:
DTSC 400 Li, RTSC 400 Li
