ATTENTION: If the device suddenly stops during operation and stops sucking, it must be turned off immediately. If
the device does not turn on after cleaning the suction pipe, contact a service center.
BAG REPLACEMENT
A damaged bag must be replaced immediately. Use only original bags. Otherwise the warranty is void.
STORAGE
Attention! The vacuum cleaner should be stored in a well-ventilated room in a dry, dust-free place out of reach of
children. Only a functional device should be stored; rectify faults before storage.
Keep the tool out of the reach of children.
Do not store the device in direct sunlight, store it in a dark place or under low-light conditions.
Do not cover the device with nylon bags as it may get wet.
The equipment should be thoroughly cleaned at the end of the season and before winter storage. Clean the bag by removing
it, emptying and washing with neutral soap under warm water. After drying, attach the bag again.
For better storage, the suction pipe can be unfolded.
If the vacum cleaner is not in use, it should be stored clean, on a flat and dry surface. If the break in operation is longer than
3 months it is necessary to:
