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 rec-
ommended due to the reduced risk of clogging) can
be connected to the extractor connector [5-1] at
the elbow.
– Static charge may occur if an anti-static suction
hose is not used. The user may suffer an electric
shock.

The extractor connector [5-1] can be rotated to
the required position when carrying out work
that does not require dust extraction.

Working with the electric power tool

Please observe all mentioned safety infor-
mations and the following rules when work-
ing:
– Only guide the machine against the workpiece
when it is switched on.
– Check the function of the pendulum guard prior
to use and do not use the electric power tool if it
does not slide in and out easily.
– 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 re-
duces the risk of injury and is a prerequisite for
precise work.

– Always push the saw forwards [7-8], and never
towards yourself.
– Adapt the infeed speed to prevent the cutters on
the saw blade from overheating and prevent
plastic materials from melting during cutting.
– Make sure that the knob [1-12] is tightened be-
fore starting work.
– Do not use the machine when the electronics are
faulty because the machine may operate at ex-
cessive speeds. An absence of the smooth start-
up function or speed control indicates that the
electronics are faulty.

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.
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.
