Festool PRECISIO CS 50 EB Operating Instructions Manual page 16

4.2 Applications
The machine can be used as a bench-moun-
ted circular saw or as a circular trimming
saw.
a) Bench-mounted circular saw
(Fig. 1)
- Set the switch (1.9) to the lower positi-
on.
- 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 po-
sition 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 positi-
on.
If the hand grip (3.9) is swung downwards,
it can be used to move the saw unit back-
wards 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 protecti-
ve cover (2.3) with a diameter of
27 mm, and the lower protecti-
ve cover (2.2) with a diameter of
35 mm.
The extraction set CS 70 AB (488292, in-
cluded in scope of delivery for CS 50 EB)
joins both 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 specifi cation on the rating
plate.
In North America, only Festool ma-
chines with the voltage specifi cati-
ons 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.
5 Electronics
The machine has full-wave electro-
nics 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 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 automati-
cally.
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
confi guration).
