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 pro-
tect 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:
6.1 Smooth start-up
The smooth start-up ensures the machine starts
up jolt-free.
6.2 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].
# n [rpm]
0
1 ~ 1600
2 ~ 2100
3 ~ 2600
The pre-selected speed remains constant whether
the machine is in operation or in neutral position.
6.3 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.
6.4 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.
6.5 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).
6.6 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.

4 ~ 3100
5 ~ 3600
6 ~ 4200

Machine settings

Prior to any setting, maintenance or re-
pair, pull the mains plug!
To make setting easier, the saw unit can be locked
in the front position (Fig. 5): pull the saw unit
forwards as far as it will go and place the switch
[5-1] in the lower position.
The machine must not be used in the front
position!
7.1 Cutting depth
The cutting depth can be set steplessly (0 - 52 mm
with 90° position of the saw blade) by turning the
crank handle [5-4].
7.2 Mitre
The saw blade can be pivoted between 0° and 45°:
- Open the rotary knob [5-3].
- Set the mitre using the scale [5-6] by turning
the handle [5-2].
- Close the rotary knob [5-3].
For exact fi tting work (relief cutting on the bor-
dering), the saw blade can be pivoted 2° beyond
the two end positions. To do so, the button [5-5]
is pressed in the end position; the saw blade can
then be pivoted up to -2° or 47°. On pivoting back,
both end positions are active once again.
7.3 Changing tools
Safety Instructions Fast-Fix Tension Nut
(see Fig. 7 A).
After tensioning, close the handle bow.
Only tighten or loosen the Fast-Fix Ten-
sion Nut by hand. Under no circum-
stances use the handle bow with aid of
screwdrivers, pliers, or other tools for
tightening or loosening.
If the nut cannot be loosened by hand, only
use a pin-type face spanner for support.
Never continue to use the Fast-Fix nut, in
case the handle bow is loose or damaged.
Due to the special shank, only the saw
blades offered by Festool for this machine
may be used.
- Open the locking mechanism [1-3] and remove
the bench insert [1-2] upwards
- Open the locking mechanism [6-1] and swing
the saw blade cover [6-2] down. This automati-
cally locks the tool spindle
- Shift the lever [7-5] and turn clockwise (left-
hand thread) to open the Fast-Fix clamp [7-4]
- Change the tool. In doing so, bear in mind:
• The Fast-Fix clamp [7-4], fl ange [8-1] and saw
blade must be clean
