Temperature cut-out
The machine power supply is limited and the speed
reduced if the motor exceeds a certain tempera-
ture. The machine continues operating at reduced
power to allow the ventilator to cool the motor
quickly. If the machine temperature exceeds the
maximum permitted value for longer periods, the
machine switches off completely after approx. 40
seconds and can only be switched on again once the
motor has cooled sufficiently.
7.2 Setting sanding motion [3]
The change-over switch [1-2] can be used to set
three different sanding motions.
 This change-over can only be carried out with
the sanding pad stationary because the switch
is locked during operation.
Coarse sanding, polishing - ROTEX rotary motion
The Rotex rotary motion is a combination
of rotary and eccentric motions. This po-
sition is selected for sanding with high
output (coarse sanding) and polishing.
Fine sanding - eccentric motion
This position is selected for sanding with
low output for a scratch-free surface
(fine sanding).
Triangular sanding and pad change [4]
This position is used for sanding with the
delta sanding pad and slat sanding pad;
the rotary motion is blocked.
You can change the sanding pad in this
position.
The stop rod [1-8] blocks the installa-
tion of the sanding pad in the change-over
switch positions ROTEX rotary motion and ec-
centric motion.
7.3 Changing sanding/polishing pad [5]
 Only use sanding and polishing pads that are
suitable for the maximum speed specified.
Tuned to the surface being processed, the machine
can be equipped with two sanding pads of different
hardnesses.
Hard: Coarse and fine sanding on surfaces. Sand-
ing edges.
Soft: Universal for coarse and fine sanding, for flat
and convex surfaces.
When the interface pad [1-12] is fitted on the sand-
ing pad, strength is reduced = extra soft.

Following the sanding pad change, switch the
change-over switch [1-2] to the desired sanding
motion.
7.4 Changing sanding pad [6]
The delta sanding pad DSS-GE-STF-RO90 can be
used for sanding close to borders, in corners or on
edges. The slat sanding pad LSS-STF-RO90 can be
used for sanding in narrow gaps, e.g. louvres.
Observe the following instructions:
Work in corners and on edges tends to subject the
tip to increased stress and results in increased heat
development. In such cases, work with reduced
contact pressure.
Delta sanding pad DSS-GE-STF-RO90 [7]
If the front tip of the StickFix pad [7-1] of your delta
sanding pad is worn, take it off and turn it 120°.
Slat sanding pad LSS-STF-RO90 [8]
If the StickFix coating of the slat sanding pad is
worn, the complete table can be replaced. Open the
screws to do this [8-1].
7.5 Attaching sanding accessories
The suitable StickFix sandpaper and StickFix sand-
ing cloth can be attached quickly and simply to the
StickFix sanding pad.

Press the self-adhesive sanding accessory onto
the sanding pad [1-7].
7.6 Attaching polishing accessories
To prevent damage, PoliStick accessories (polish-
ing sponges, polishing felt, sheepskin) must only be
used on the special polishing pad.

Press the self-adhesive polishing accessory
onto the sanding pad [1-9].
7.7 Dust extraction
WARNING
Dust hazard

Dust can be hazardous to health. Always work
with a dust extractor.

Always read applicable national regulations be-
fore extracting hazardous dust.
At the extractor connector [1-5], a Festool mobile
dust extractor with an extraction hose diameter of
27 mm can be connected.
7.8 Edge protector [9]
The edge protector [1-1] reduces contact of the
sanding pad circumference with a surface (e.g.
when sanding along a wall or a window), thus pre-
venting back-kick of the machine, or machine dam-
age.
