full load. The machine requires less time to cool
down when idling.
LED indicator
The rotary sander is fitted with an electronic
adjusting wheel and a green and red LED [1-3].
A green lit LED indicates that the rotary sander
is operating in normal mode. A red lit LED indi-
cates that the motor is operating at approx. 70%
overload. The overload or temperature cut-out
switches off the motor if overloaded for longer
periods.
However, alternately fl ashing green and red LEDs
indicate that the brushes are completely worn
(remaining working hours max. 10 hours). In
this case, have an authorised after-sales service
workshop replace the carbon brushes the next
day. Always replace these brushes with special
carbon brushes available in pairs otherwise the
LED indicators will not work.
7.2 Changing the brushes
Loosen the screw [2-1].
Swivel the silver cover [2-2] down.
Press and hold the spindle lock [2-3] and un-
screw the hexagon nut (size 24) on the brush.
Insert a different brush.
Secure the brush with the hexagon nut and
tighten it. Close the silver cover [2-2] and refi t
the screw [2-1].
Use the centring rings provided for the LD
85 and BG 80 brushes. These must be press-
fi tted using a suitable tool until they are fl ush
with the stop.
7.3 Adjusting the texture depth
Set the required texture depth using the
thumbwheel [1-6].
7.4 Dust
extraction
CAUTION
Breathing in dust damages the respiratory
passage.
Always connect the machine to a dust ex-
tractor.
When performing work that generates dust,
always wear a dust mask.
You can connect a Festool extractor to the extrac-
tor connector [1-7]. The extractor hose in the
Festool extractor is 27 mm in diameter.

Working with the machine
The RUSTOFIX gives beams or wooden panelling
a rustic texture.
Working method
After the fi rst working procedure with the wire
brush LD 85, protruding fi bres give the wooden
surface a rough feel. In the second working pro-
cedure, plastic bristles KB 85 sand the textured
surface to lend a smooth fi nish.
Always guide the machine evenly and in the
direction of the grain.
Hold the machine with both hands to ensure
safe guidance.
Do not overload the machine by pressing with
excessive force! The best results are achieved
with moderate application pressure.
Maintain the speed specifi ed. (see Chapter 7.1)
Use the correct brush for the relevant working
procedure:
