2. Clean the dust filter with a brush.
9.5 Cleaning the Dust Filter
DANGER

Depending on the dust load, clean the dust filter at least once a week.
1. Switch off the vacuum generator.
2. Carefully tilt the lifting device onto its side.
3. Clean the dust filter (10) with a brush.
9.6 Cleaning the lifting device
The lifting device must only be cleaned with an agent containing active tensides (pH-neutral).
Never clean the device with a high-pressure cleaner, as the water jet may damage electri-
