Dust extraction

WARNING
Dust hazard
Always work with a dust extractor.

Always observe country-specific regulations.

 For use of a Festool mobile dust extractor with
flow sensor: Adjust hose diameter of mobile
dust extractor to Ø 27 mm.
To guarantee optimal dust extraction, we recom-
mend using Festool extractors with automatic
switch-on/switch-off device for compressed air
machines.
In order to prevent damage to the pneumatic
motor, dust extraction must not be carried out on
the pneumatic tool when it is at standstill.
8 Working with the machine
Please observe all mentioned safety informa-
tions and the following rules when working:
– Always secure the workpiece in such a manner
that it cannot move while being processed.
For work that generates dust, wear a dust
mask.


from the compresses air supply before any work
is carried out on the machine.

9.1 Vanes
We recommend that the vanes on the motor be re-
placed after approx. 2000 operating hours.
9.2 Replacing the silencer
In order to maintain the power and performance of
the compressed air tool, replace the silencer on the
IAS hose systems at regular intervals.
9.3 Sanding pad brake
The rubber sleeve [5-1] brushes off the sanding
pad and prevents uncontrolled turning of the sand-
ing pad. This must be replaced if the braking effect
decreases.
9.4

Cleaning the extraction channels

We recommend cleaning the extraction channels in
the machine [5-2] roughly once a week (particularly if
sanding synthetic resin, in the case of wet sanding and
if sanding plaster) using a small flat brush or a cloth.
