Connecting electric power tools
WARNING
Risk of injury
► Observe the maximum appliance socket
connected load (see chapter "Technical da
ta")
► Switch off the electric power tool.
–
Always use the socket on the machine for
the purpose specified!
► Connect the electric power tool to the appli
ance socket [1-3].
8.2
Connecting pneumatic tools
WARNING
Risk of injury
► Switch off the air tool.
If the compressed air module [1-2] (496141) is
installed, the automatic switch-on function of
the mobile dust extractor also works in combi
nation with pneumatic tools.
We also recommend installing the VE service
unit (495886). The service unit filters and lubri
cates the compressed air and enables an ad
justment of the air pressure. An IAS adapter
(454757) is available to connect Festool pneu
matic tools to the IAS system.
The operating pressure of the tool must be
6 bar for the automatic switch-on unit to func
tion correctly.
8.3
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, allow
to cool for about 5 minutes then switch on
again.
Not possible to switch on: contact Festool
service workshop.
8.4
Adjusting the suction power
You can use the suction power adjuster [1-8] to
adapt the machine suction power to different
applications.
8.5
AUTOClean - Cleaning the main filter
(only versions with AutoClean)
To maintain a constant suction power when ex
tracting fine dust, you can adjust the frequency
12
of the automatic [1-7] cleaning system in infin
ite variables using the rotary knob. Always use
the automatic cleaning system in combination
with a disposal bag (in line with dust class 'M'
requirements).
Before performing wet extraction tasks
or working with a filter bag, set the [1-7]
rotary knob to position 0.
► Set the automatic cleaning function to the
highest setting when [1-7] extracting large
quantities of dust.
Manual cleaning
If the suction power decreases, cleaning
can be started manually by turning the
switch [1-9] to the AC symbol positioned on ei
ther side of the switch.
We recommend cleaning the main filter com
pletely if severely clogged:
► Set the suction power adjuster [1-8] to the
maximum setting.
► Cover the end of the nozzle or suction hose
with your hand for 10 seconds.
► Turn the switch [1-9] to the AC symbol.
When the CT-VS closing slide is used (or
der no.: 497926), the filter can be cleaned
fully without removing the connected elec
tric power tools.
In intensive applications that generate adherent
dust, it may be necessary to clean the filter ele
ment mechanically under certain circumstan
ces (extract). Wear a dust mask!
