7.6 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.
Festool mobile dust extractor
A Festool mobile dust extractor with an extractor
hose diameter of 27 mm or 36 mm (36 mm is recom-
mended due to the reduced risk of clogging) can be
connected to the extractor connector [1-10] at the
elbow.
– Static charge may occur if an anti-static suction
hose is not used. The user may suffer an electric
shock.
Independent extraction
Secure the connection piece [6-2] of the dust col-

lection bag [6-3] at the extractor connector with
a clockwise rotation [6-1].
To empty remove the connection piece [6-2]of the

dust collection bag [6-3]from the extractor con-
nector with an anti-clockwise rotation [6-1].
8 Working with the electric power tool
Please observe all mentioned safety informa-
tions and the following rules when working:
– Only guide the power tool towards the workpiece
when it is switched on.
– Before each use, check that the pendulum
guard is working correctly. Only use this power
tool when it is in perfect working order.
20
– Always secure the workpiece in such a manner
that it cannot move while being processed.
– Always hold the machine with two hands at the
handles [1-1] when performing work. This reduc-
es the risk of injury and is a prerequisite for precise
work.
– Always push the saw forwards [8-9], and never to-
wards yourself.
– Adapt the infeed speed to prevent the cutters on
the saw blade from overheating and prevent plas-
tic materials from melting during cutting.
– Make sure that the knob [1-12] is tightened before
starting work.
– Do not work on the power tool if its electronics
are defective as this may lead to excessive
speeds. Defective electronics mean that there is
no smooth start-up and the speed regulation
fails.

8.3 Sawing cut-outs (plunge cuts)
In order to avoid kickbacks, the following in-
structions must be observed without fail when
plunge cutting:
– Always position saw with the rear edge of the saw
table against a fixed stop.
– When working with the guide rail, place the saw
against the kickback stop FS-RSP (accessories)
[8-6] clamped to the guide rail.
Caution! Danger of crushing!
Always keep a firm grip on the machine with
your free hand when adjusting plunge cuts. Never
position your fingers behind or below the saw blade.
