2. Wet vacuuming
WARNING
Never operate the machine without inserting filter or
special wet filter. The machine may be destroyed and
water may also escape.
○ Before carrying out any wet vacuuming, remove the dry
vacuumed material. This process will prevent severe
soiling and encrustation.
○ The appliance has a float system that enables it to
switch off the air flow when the maximum liquid level is
reached. When this happens, you will hear a distinct
change in the sound of the motor. Then switch off the
appliance and pull the plug from the socket. Only
vacuum liquids when the float is functioning properly
(see maintenance).
○ After switching off, some water may run back out of the
hose.
○ Before emptying, first of all take the suction hose out of
the liquid.
○ If you are then going to dry vacuum, insert a dry filter. If
there is frequent switching between dry and wet
vacuuming, we recommend the use of a second
(replacement) filter. Allow the filter, container and
accessories to dry: otherwise dust may adhere to damp
components.
○ Before storage: leave humid filter and the inside of the
dust container to dry completely.
3. Transport
○ L class: Leave the hose on the machine to prevent dust
from accidentally being released. (Fig. 13)
○ M and H class: with the hose disconnected, close the
suction inlet with the plug. Insert the hose ends into
each other so that no dust can escape from the hose.
○ Secure the suction hose or mains connection lead to
the appliance using the accessory fixture and rubber.
○ The upper part must be securely sealed to the container
- check that the snap locks are closed.
WARNING
The handle is only permitted for manual transport - not
for attachment to cranes or similar!
