With the compressed air module
[1-3]
, the automatic
switch-on function for the mobile dust extractor also
works in conjunction with air tools.
We also recommend installing the VE service unit
(495886). The service unit filters and lubricates the
compressed air and enables an adjustment of the air
pressure. An IAS adapter (454757) is available to con-
nect Festool air tools to the IAS system.
The operating pressure of the tool must be 6 bar for
the automatic switch-on unit to function correctly.
7.4
Connecting the energy box
The connection for the energy box (EAA)
[1-4]
allows
you to connect the mobile dust extractor with the EAA
in order to couple the automatic switch-on unit on the
mobile dust extractor with the equivalent unit on the
EAA.
7.5
Adjusting the suction power
Use the rotary knob
[1-10]
.
7.6
Applying the brake
Folding out the black brake lever
[1-15]
prevents the
mobile dust extractor from rolling. To achieve this,
lift the front end of the mobile dust extractor slightly
and push the black brake lever downwards until it
latches into place. Push the green lever
[1-14]
again
to release.
7.7
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 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.
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]
and close the lock-
ing 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.

SysDoc SYSTAINER attachment system:
A SYSTAIN-
ER can be attached to the storage area using the four
locking latches

.
8.2
Extracting dry materials
Possible causes
Solution
Value set on the suction power adjuster
[1-10]
is
too low.
Set the suction power adjuster to a higher value (see
Chapter 7.5).
Rotary knob
[1-8]
not set to the correct hose
diameter.
Set the knob to the correct hose diameter (see Chap-
ter 7.1).
Suction hose blocked or kinked.
Remove blockage or kink.
Filter bag full.
Insert a new filter bag (see Chapter 7.8).
Dirty main filter.
Changing the main filter (see Chapter 9.1).
Monitoring electronics malfunction.
Send to a Festool service workshop for repair.
Wet extraction.
Functional reliability not affected, no actions required.
CAUTION
Hazardous dust
Damage to the respiratory passage
Always use a filter bag when extracting hazard-
ous materials!
Do not use the machine if the volumetric flow
monitoring function is inactive.
