for machine comparisons. They are also used for
making preliminary estimates regarding vibration
and noise loads during operation.
The emission values specifi ed refer to the main
applications for which the power tool is used. If
the electric power tool is used for other applica-
tions, with other tools or is not maintained suf-
fi ciently prior to operation, however, the vibration
and noise load may be higher when the tool is
used. Take into account any machine idling times
and downtimes to estimate these values more
accurately for a specifi ed time period. This may
signifi cantly reduce the load during the machine
operating period.
3 Power supply and start-up
Observe mains voltage: the voltage and
frequency of the power source must
correspond to the specifi cation on the
machine rating plate.
In North America, only Festool machines with the
voltage specifi cations 120 V/60 Hz may be used.
On/Off switch
Switch (1.3) serves as an On/Off switch (press =
ON, release = OFF). It may be latched with the
locking knob on the side (1.2) for continuous op-
eration. Pressing the switch again releases the
lock.
4 Machine settings
Always remove the power supply plug
from the socket before carrying out any
work on the machine.
4.1 Speed adjustment (BS 105 E)
You can adjust the speed steplessly using the ad-
justing wheel (2.5). This enables you to optimise
the cutting speed to suit the material (see table).
Several factors infl uence the sanding speed (e.g.
workpiece consistency, sanding belt and grit
manufacturer, skill of the user) and so tests must
be performed before sanding work commences
to establish the best speed.
The values listed in the table are only recom-
mended.

4.2 Changing tools
- Push the lever (3.6) forwards to slacken the
sanding belt.
- Remove the old sanding belt.
- Attach a new sanding belt.
Important: When inserting the sanding belt,
make sure that the running direction of the belt
(usually indicated by an arrow on the inside)
matches the running direction of the machine
(3.5).
- Return the lever (3.6) to its original position.
- Switch on the machine and check that the sand-
ing belt is running smoothly. The sanding belt
must run centrally across the sanding base (3.4).
If this is not the case, use the rotary knob (3.1)
to adjust the position of the sanding belt.
4.3 Dust extraction
Always connect the machine to a dust
extractor when performing work that
generates dust.
Inboard extraction
Slide the connector (4.3) on the dust bag (4.1) onto
the extractor opening (4.2) and turn clockwise to
secure.
Make sure that the plate springs (4.5) touch the
belt casing on the machine.
Turn the connector anticlockwise to remove and
empty the bag.
External extraction by an extraction unit
Attach the adapter (4.4) to the extractor opening
(4.2) instead of the dust bag.
A Festool dust extractor with an extractor hose
diameter of 36 mm or 27 mm can be connected
to the adapter.
4.4 Cooling air
Position the air guide fl ap (1.1) so that the escap-
ing air does not disturb you.
