4.2
Transport
- Engage the saw unit in the zero position.
- Remove all attachments from your saw and wind
up the cable on the cable holder.
- Fold up the legs.
4.3
Applications
The machine can be used as a bench-mounted
circular saw or as a circular trimming saw.
a)
Bench-mounted circular saw (Fig. 1)
- Set the switch (1.9) to the lower position.
- Swing the hand grip (1.8) downwards, and use
the hand grip to pull the saw unit forwards until
it locks into place.
The saw unit is now in a central bench position
and the machine can be used as a bench-mounted
circular saw.
b)
Circular trimming saw (Fig. 3)
- Set the switch (3.10) to the upper position.
If the hand grip (3.9) is swung downwards, it can
be used to move the saw unit backwards and for-
wards for drawing cuts. The backward movement
is supported by spring force.
4.4
Dust extraction
The PRECISIO has two extraction con-
nections: the upper protective cover (2.3)
with a diameter of 27 mm, and the lower
protective cover (2.2) with a diameter of
35 mm.
The extraction set CS 70 AB (488292, included in
scope of delivery for CS 50 EB) joins both of the
extraction connections so that a Festool extractor
module can be connected.
4.5
Power supply and start-up
The mains voltage must correspond to
the specifi cation on the rating plate.
In North America, only Festool machines
with the voltage specifi cations 120 V/60
Hz may be used.
On account of the performance capability of the
motor, we recommend a 16 A fuse.
To switch on, press the ON/OFF switch (4.1) and
the locking switch (4.4) simultaneously. The
machine runs as long as the ON/OFF switch is
pressed.
For continuous operation after switching on, fi rst
press the ON/OFF switch (4.1) and then let go of
the locking switch (4.4). To switch off continuous
operation, either press the ON/OFF switch again
and let it go or press the red switch (4.6). To protect
against unauthorised activation, a shackle type
connector can be inserted in the hole (4.2) of the
ON/OFF switch.

Electronics
The machine has full-wave electronics
with the following features:
5.1
Smooth start-up
The smooth start-up ensures the machine starts
up jolt-free.
5.2
Speed adjustment
You can regulate the speed steplessly between
1600 and 4200 rpm using the adjusting wheel (4.5).
This enables you to optimise the cutting speed to
suit the material (4.3).
The pre-selected speed remains constant whether
the machine is in operation or in neutral posi-
tion.
5.3
Overload protection
In the event of an extreme overload of the ma-
chine, the power supply is reduced. If the motor
is blocked for a longer period, the power supply
is interrupted completely. After removal of the
blockage or switching on again, the machine is
operational once again.
5.4
Temperature protection
If the motor temperature becomes too high, the
power supply and speed are reduced. The ma-
chine then only runs with reduced power to enable
rapid cooling by means of the motor ventilation.
After cooling down, the machine accelerates again
automatically.
5.5
Brake
After switching-off the tool, the saw blade is elec-
tronically brought to a standstill in 1.5 – 2 seconds
(only for 230 V - 240 V confi guration).
5.6
Restart protection
The built-in undervoltage release prevents that
the machine restarts on its own in the continu-
ous operation mode following a power cut. In this
case, the machine must fi rst be switched off and
then on again.

Machine settings
Prior to any setting, maintenance or re-
pair, pull the mains plug!
