6.3 CVR 4000 Display
CVR 4000 has a display giving information about the
machine, Fig. 19.
Speed level
Shows at which of the five speed levels the machine is
operating.
Indicator for dust bag/bag filter
When the dust bag/filter symbol starts flashing
during operation, the cleaner tells you that it is
almost time to clean the bag filter and replace the dust bag/
empty the container. When it is time to do so, symbol will be
lit continuously. The dust bag/filter symbol will be lightened
after every 20 operation hours of the cleaner at the latest.
Reduced airflow indicator - lit
The reduced airflow symbol on the display indicates
that the airflow through the vacuum cleaner is
reduced. After 30 seconds of operation with reduced airflow,
the vacuum motor will be shot down in order to prevent
damage to the motor. If the reduced airflow symbol is lit and
the motor has been shot down, do like this: Check the bag
filter and dust bag (see Sections 7.1, 7.2, 7.3 and 7.4) to see
if anything is blocking the airflow. Also check that nothing is
blocking suction hose and/or vacuum sockets. Remove the
material causing the reduced airflow symbol to indicate.
Service indicator
When the service symbol starts flashing, the motor
will run for one more hour before it stops/will not
start. The purpose of the service symbol is to inform
you that it is time to order service of the cleaner. When
the symbol is continuously lit, the run time counter in the
cleaner has counted that the allowed amount of run time
has passed. You must now contact an authorised service
workshop and let them perform a service of the cleaner and to
reset the run time counter.
Overheat indicator - flashing
The overheat symbol indicates that the cleaner has
become overheated. The cleaner stops automatically.

Unplug the main power cord to reset the vacuum cleaner and
wait 5-10 minutes to allow the machine to cool down. While
you are waiting, check the bag filter, container/dust bag,
suction hose and vacuum sockets to be sure that nothing is
blocking the flow of air through the machine.
Signal indicator - flashing
When the symbol is flashing, the hose handle is out of
range and there is no connection to the cleaner. The cleaner
will automatically stop after 30 min. if the hose handle or the
cleaner has not been activated.
