3.3 Residual risks
In spite of compliance with all relevant design
regulations, dangers may still present them-
selves when the machine is operated, e.g.:
- Workpiece parts being thrown off,
- Parts of damaged tools being thrown off,
- Noise emission,
- Sawdust emission.

Setting up, commissioning

Ensure that the floor around the machine is
level, in good condition and free of loose
objects (e.g. chips and offcuts).
4.1

Mounting the machine

The machine can be set up with or without the
legs folded out (Fig. 1 and 2) (the „Floor“
model does not include folding legs).
To fold out the legs, open the four rotary knobs
(1.6) as far as they will go. After folding out
the legs, retighten the four rotary knobs.
So that the machine stands securely, the length
of one of the legs can be changed by turning
the cap on the end (1.7).
4.2 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 forwards for drawing cuts. The backward
movement is supported by spring force.
4.3 Dust extraction
The PRECISIO has two extraction
connections: 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 (488 292, included
in scope of delivery for CS 50 EB) joins both
84 / 90 dB(A)

of the extraction connections so that a Festool
extractor module can be connected.
4.4 Power supply and start-up
The mains voltage must correspond to the
specification on the rating plate.
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,
first 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 router starts
up jolt-free.
5.2

Speed adjustment

You can regulate the speed steplessly between
1600 and 4200 min-1 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 neu-
tral position.
5.3 Overload protection
In the event of an extreme overload of the
machine, 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
machine 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
electronically brought to a standstill in 1.5 – 2
seconds (only for 230 V - 240 V configuration).
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 first be switched
off and then on again.
