- The machine is not allowed to be operated by a
person under 16 years of age.
- Only for AS/NZS: The tool shall always be sup-
plied via residual current device with a rated re-
sidual current of 30 mA or less.

Emission levels
Measured values determined according to EN 60 745.
Typically the A-weighted noise level of the tool are:
Sound pressure level:
Sound power level:
Inaccuracy of measurement
CAUTION
Operating noise
Damage to hearing
Use ear protection!
Measured values determined according to EN 60 745.
Grinding with grinding wheel
Inaccuracy of measurement
The specifi ed emissions values (vibration, noise)
– are used to compare machines.
– They are also used for making preliminary esti-
mates regarding vibration and noise loads during
operation.
– They represent the primary applications of the
power tool.
Increase possible for other applications, with oth-
er insertion tools or if not maintained adequately.
Take note of idling and downtimes of machine!

Activation
WARNING
Risk of accident if the machine is operated us-
ing unauthorised voltages or frequencies.
The mains voltage and the frequency of the
power source must correspond with the
specifi cations on the machine's name plate.
In North America, only Festool machines with
the voltage specifi cations 120 V/60 Hz may
be used.
61 Switching on – off
Switching on
Move the switch button [1-2] forward and the de-
vice will switch on. If you press the front part of the
button, it will arrest and start continual operation.

Switching off
Press the rear part of the button [1-2] to relax ar-
rest. The button returns to switched-off position.
6.2
Starting current limitation
Electronically controlled continual running se-
cures device acceleration without back thrust.
Due to starting current limitation in the device,
15A protection is suffi cient.
86 dB (A)
97 dB (A)
K = 1.5dB (A)
Devices without starting current limitation
need higher protection – at least 16A circuit
breaker.
Switching off during back thrust
During sudden drop of revolutions, for example
blocking in dividing cut, the current input in mo-
tor stops. For re-starting, the device must be fi rst

Protection against re-starting
Prevent uncontrolled starting of the device after
current supply cut off. For re-starting, the device
must be fi rst switched off and again switched on.
Revolutions pre-setting
Use the revolutions regulator [1-3] for smooth
revolutions pre-setting.
Degree 1: 2000 min
Degree 2: 2950 min
Degree 3: 3750 min
Required number of revolutions depends on ap-
plied grinding wheel and worked material.
Constant electronics
Constant electronics maintains revolutions during
operation and idle run near the constant. Regular
operating shift is achieved.
Protection from overloading dependant on
temperature
The safety electronics switches to cooling regime
when the critical temperature is reached. Motor
continues running at approximately 2500 min
revolutions, constant electronics is deactivated.
After cooling to approximately 10 – 20 s, the device
is fully operational.
Heat protection for devices heated during opera-
tion, reacts adequately sooner.
