Temperature cut-out
A temperature cut-out switches the mobile dust ex-
tractor off when it reaches a critical temperature to
prevent overheating.
Switch off the mobile dust extractor and allow to
cool for approx. 5 minutes.
Change the cooling air filter if necessary (see
chapter 9.2).
If the mobile dust extractor will not switch on
again, please contact a Festool service work-
shop.

and remove the top
section of the machine
[2-1]
.
Remove the filter bag.
Dispose of the used filter bag in accordance with
statutory regulations.
Inserting the filter bag [5]
Insert a new filter bag (SC-FIS-CT 48) in the inlet
port of the dust container and interlock it.
Im-
portant:
be aware that the locking engages.
Make sure that the filter bag is not pinched be-
tween the top and bottom sections.
Replace the top section
[2-1]

8.2
Extracting dry materials
Observe the following
when extracting dust gener-
ated by operating electric power tools:
If the exhaust air is discharged back into the room,
the
air renewal rate L
within the room must be suf-
ficient. The volume of air discharged back into the
room must not exceed 50% of the fresh air volume
flow (room volume V
R
x air renewal rate L
W
). Ob-
serve all the relevant regional regulations.
Remember:
A moist main filter clogs more quickly
when extracting dry materials. Therefore, dry the
main filter before extracting dust or replace the
damp filter with a dry one.
8.3
Extracting fluids
Before extracting fluids, remove the filter bag (see
Chapter 7.8). We recommend using a special wet
filter.
The dust extractor stops automatically when the
maximum level is reached.
Possible causes
Solution
