– Install an upstream residual-current cir-
cuit-breaker (FIG, PRCD).
– Connect the machine to a suitable dust ex-
tractor.
– Regularly remove dust deposits in the mo-
tor housing.
5.4 Emission levels
Levels determined in accordance with EN
60745 are typically:
Vibration emission value a
h
(vector sum for
three directions) and uncertainty K mea-
sured in accordance with EN 60745:
The specified emissions values (vibration,
noise)
– are used to compare machines.
– They are also used for making preliminary
estimates regarding vibration and noise
loads during operation.
– They represent the primary applications of
the power tool.
Increase possible for other applications, with
other insertion tools or if not maintained ad-
equately. Take note of idling and downtimes
of machine!
6 Operation
Connecting and detaching the mains power
cable [1-4] see Fig. [2].
The switch [1-3] is an on/off switch (I = ON,
0 = OFF).
L
The circuit closer can only be actuated if
the change-over switch [1-2] is in an en-
gaged position.
L
In case of a power failure or if the mains
connector is removed, move the on/off
switch immediately to the Off position.
This prevents uncontrolled restarting.
7 Settings
7.1 Electronics
The machine features full-wave electronics
with the following features:
Smooth start-up
The electronically controlled smooth start-up
ensures that the machine starts up jolt-free.
Speed control
You can regulate the speed steplessly with
the adjusting wheel [1-6] in the speed range
(see Technical data). This enables you to op-
timise the cutting speed to suit the surface
(see table).
Constant speed
The preselected motor speed remains con-
stant through electronic control to ensure a
uniform cutting speed even when under load.

WARNING
Unauthorised voltage or frequency!
Risk of accident
X
The mains voltage and the frequency of
the power source must correspond with
the specifications on the machine's name
plate.
X
In North America, only Festool machines
with the voltage specifications 120 V/60
Hz may be used.
WARNING
Risk of injury, electric shock
X
Always pull the plug out of the socket be-
fore performing any type of work on the
machine!
