WARNING
Risk of injury
Rebound, ejected parts
 Before setting down the machine, wait until
the rotating tool has come to a complete stop.

Motor electronics

Starting current limitation
Electronically controlled continual running se-
cures device acceleration without back thrust.
WARNING
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
switched off and again switched on.
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 [1-4] for smooth
revolutions pre-setting.

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 tem-
perature
The safety electronics switches to cooling regime
when the critical temperature is reached. Motor
continues running at approximately 50 % revolu-
tions, 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.

9.3 Turning the gear box
For special cases, the gearbox can be turned in
steps of 90°. This achieves a better handling posi-
tion of the switch.
For such work, we recommend to use the Festool
service.
 Remove four screws.
 Carefully, turn the gearbox into required position.
Make sure the gearbox does not separate from
motor box by more than approximately 1 mm.
 Insert and fasten the four screws [5].
9.4 Sliding front segment [6]
For working close to edges.
10 Service and maintenance
WARNING
Risk of accident, electric shock
 Always pull the plug out of the socket before
performing any type of work on the machine.
 All maintenance and repair work which re-
quires the motor housing to be opened, must
only be carried out by an authorised service
workshop.
- Wrapped electric tools can be stored in a dry
place without heating, with temperatures not
lower than –5°C. Unwrapped electric tools can
only be stored in dry places with temperatures
not lower than +5°C, without sudden changes
in the temperature.
- To ensure the airfl ow is suffi cient, cooling
openings of the motor must be always clean
and free.
- The machine is equipped with special self-
disconnecting brushes. When the brushes are
worn, the power supply is automatically discon-
nected, and the machine is stopped.
- If the suction fl ange height adjustment system
does not operate smoothly, the fl ange must be
removed and cleaned.
