Temperature cut-out

A temperature cut-out switches the mobile dust
extractor off when it reaches a critical tempera­
ture to prevent overheating.
► A temperature cut-out switches the mobile
dust extractor off when it reaches a critical
temperature to prevent overheating.
► Switch off the mobile dust extractor and al­
low 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
workshop.
7.8 Changing the filter bag (SC-FIS-CT 48)
Removing the filter bag [4]
► Open the locking clips [2-2] 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. Important: be aware that the locking en­
gages.
Make sure that the filter bag is not pinched
between the top and bottom sections.
► Replace the top section [2-1] and close the
locking clips [2-2].
7.9 Volumetric flow monitoring (only CTM
48 E LE EC)
An acoustic warning signal sounds if the air
speed in the suction hose falls below 20 m/s.
Possible causes
Value set on the
suction power ad­
juster [1-10] is too
low.
Rotary knob [1-8]
not set to the correct
hose diameter.
Suction hose
blocked or kinked.
Filter bag full.

).
Solution
Set the suction power
adjuster to a higher
value (see Chapter
7.5 ).
Set the knob to the
correct hose diameter
(see Chapter 7.1 ).
Remove blockage or
kink.
Insert a new filter bag
(see Chapter 7.8 ).
Possible causes
Dirty main filter.
Monitoring electron­
ics malfunction.
Wet extraction.

SysDoc SYSTAINER attachment system: A
SYSTAINER can be attached to the storage area
using the four locking latches [6-1].

Extracting dry materials

CAUTION
Hazardous dust
Damage to the respiratory passage
► Always use a filter bag when extracting
hazardous materials!
► Do not use the machine if the volumetric
flow monitoring function is inactive.
Observe the following when extracting dust
generated 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 sufficient. The volume of air dis­
charged back into the room must not exceed
50% of the fresh air volume flow (room volume
V x air renewal rate L
R
vant regional regulations.
Remember: A moist main filter clogs more
quickly when extracting dry materials. There­
fore, 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 spe­
cial wet filter.
The dust extractor stops automatically when
the maximum level is reached.
CAUTION
Escaping foam and fluids
► Switch off the machine immediately and
empty the dirt trap.
