Electronics; Settings On The Machine - Festool PRECISIO CS 50 EG Original Instructions Manual

- In North America, only Festool machines with
the voltage specifications 120 V/60 Hz may be
used.
- We recommend using a 16 A fuse because of the
performance of the motor.
- Before use always inspect the flexible lead and
the plug. Have the defects repaired by a speci-
alist repair shop.
- Outside the premise use only approved extensi-
on leads and cable connections.
To switch the power tool on, press the ON/OFF
switch [4-1] and the locking switch [4-4] at the
same time. The machine will run as long as the
ON/OFF switch remains pressed.
For continuous operation once the power tool has
been switched on, release the ON/OFF switch
[4-1] first and then release the locking switch
[4-4]. To switch continuous operation off, either
press the ON/OFF switch again and then release
it, or press the red switch [4-6].
To prevent the device from being switched on
without authorisation, a U-lock can be fitted to
the ON/OFF switch hole [4-2].
5.7 Extra feet [1-11] [1-12]
Always use the extra feet with an extension table
(width or length) or sliding table. Loosen the screw
[1-11], swivel the leg [1-12] down until it has set-
tled on the floor and retighten the screw [1-11].
5.8 Installing the accessory holder (fig. 13)
When connecting the two individual parts, make
sure that the tabs on the latches fit together ex-
actly and lock in place. Also check the back of the
accessory holder to make sure the latches are in
the correct position in the holding brackets.
5.9 Cuts along the mitre
For cuts along the mitre, the preset profile setting
rail should be on the right-hand side of the table.
5.10 Switching on the machine when cutting
metal
When cutting metal, switch on the saw using a
residual current circuit breaker.

Electronics

The machine features full-wave electron-
ics with the following properties:
6.1 Smooth start-up
The electronically controlled smooth start-up
function ensures that the machine starts up
smoothly.
6.2 Speed control
The rotational speed is infinitely adjustable be-
tween 1600 and 4200 rpm using the adjusting
wheel [4-5]. This enables you to optimise the
cutting speed to suit the respective material [4-3].
# n [rpm]
0
1 ~ 1600
2 ~ 2100
3 ~ 2600
The preselected motor speed is kept constant
through electronic control. This ensures a uniform
cutting speed even when under load.
6.3 Overload safety device
The power supply is restricted if the machine is
overloaded to extremes. The power supply is dis-
connected completely if the motor jams for some
time. You will need to remove the load and/or
switch off the machine before you can use it again.
6.4 Temperature cut-out
The power supply is restricted and the speed re-
duced if the motor exceeds a certain temperature.
The machine continues operating at reduced power
to allow the ventilator to cool the motor quickly.
The machine starts up again automatically once
the motor has cooled sufficiently.
6.5 Brake
After switching off the tool, the saw blade is elec-
tronically brought to a standstill in 1.5-2 seconds
(only in 230-240 V models).
6.6 Restart protection
The built-in undervoltage release prevents the
machine from starting up again automatically if
the power is disconnected during continuous use.
In this case, the machine must be switched off and
then switched back on again.

Settings on the machine

Always pull the mains plug before main-
taining, servicing or making any kind of
adjustment.
To make adjustments easier, the saw unit can be
locked in place in the central position (fig. 5): Pull
the saw unit forward up to the stop and set the
switch [5-1] to the lower position.
7.1 Cutting height
The cutting height can be continuously adjusted
(0 - 52 mm when the saw blade is set to 90°) by
turning the crank [5-4].
