Vacuuming cold ashes
Device damage
Only vacuum cold ash with an ash pre-separator.Defective or wet foam filter / cartridge filter
Device damage
Before starting up, check the foam filter / cartridge filter for damage, and replace it if necessary. Only vacuum with a dry foam filter / cartridge filter.Depending on the equipment variant, a foam filter or a cartridge filter is included.
For devices with a foam filter: Always use the filter bag in addition to the foam filter when dry vacuuming.
For devices with a cartridge filter: Always use the filter bag in addition to the cartridge filter when vacuuming fine dust.
Replace the filter bag in good time, as a filter bag that is too full could be damaged. The fill degree of the filter bag depends on the amount of dirt vacuumed. The filter bag should be replaced more frequently when vacuuming fine dust, sand, etc.
Wet vacuuming with a filter bag
Device damage
Do not use a filter bag when vacuuming wet.Operation with full container
When the container is full, a float switch closes the suction opening and the device runs at a higher speed.
Switch off the device immediately and empty the container.If the device falls over, the float can also close. To make the device capable of vacuuming again, set up the device, switch it off, wait 5 seconds and then switch it on again.
The blower function can be used to clean areas that are difficult to reach or where vacuuming is not possible, e.g. leaves in a gravel bed.
Insert the suction hose into the blower connection. The blower function is now activated.

Set the trigger to "0 OFF".
The device is switched off.
