Working with power tools
DANGER
Danger of electric shock
Risk of injury and damage.
The socket is only intended for direct connection of pow-
er tools to the vacuum cleaner. Any other use of the
socket is prohibited.
1. Plug the mains plug of the power tool into the power
socket on the vacuum cleaner. The vacuum cleaner
is in Standby mode.
2. Switch on the device at the turn switch.
Note
The vacuum cleaner is automatically switched on and
off with the power tool.
Note
The vacuum cleaner has a startup delay of up to 0.5
seconds and an after-running time of up to 15 seconds.
Note
See the Technical data for the permissible power rating
of the power tool.
3. Remove the angle piece from the suction hose.

4. Install the tool adapter on the suction hose.
5. Connect the tool adapter to the power tool.
Illustration O
6. Set the minimum volume flow on the turn switch for
suction hose cross section. The scale shows the
suction hose suction hose cross section.
Note
The different suction hose cross sections are necessary
in order to adapt to the different connection cross sec-
tions of the processing machines.
Note
For operation as a dust removal device for mobile oper-
ation (processing machine plugged into the vacuum
cleaner) the integrated monitoring system must be ad-
justed to suit the connected processing machine (dust
generator). This means that the user must be warned
when the flow rate drops below the minimum value 20
m/s needed for correct vacuuming.
Note
Information on the minimum flow rate depending on the
vacuum can be found on the type plate.
Automatic filter dedusting
The device is equipped with a special filter dedusting
function, which is particularly effective against fine dust.
The flat fold filter is automatically cleaned every 15 sec-
onds (AUTO MAX) or every 60 seconds (AUTO MIN) by
a blast of air (pulsing noise).
1. Set the turn switch to the desired program (AUTO
MIN-AUTO MAX).
2. Power dedusting (for particularly severe contamina-
tion of the flat fold filter): Set the turn switch to pro-
gram 2, seal the suction pipe or bender with your
hand and wait for the automatic filter cleaning to fin-
ish (lasts 15 seconds).

cleaning.
3. Remove the suction hose with floor nozzle from the
support. Carry the device by the carrying handle and
the suction pipe, not by the push handle.
4. When transporting the device in vehicles, secure it
to prevent it from slipping or overturning in accord-
ance with the respective valid guidelines.

vention or elimination of hazards according to the Ger-
man DGUV regulation 1 (German accident prevention
regulation, principles of prevention).
Note
