Emptying
a – Container
The container underneath the cyclone should be emptied when about 2/3 full.
c – Plastic bag
You must clean the filters before replacing the plastic bag. It should be replaced when
the dust level is about 5 cm below the discharge flap.
Clean the filter and use the dust extractor.
L – Longopac
Close the bag using the supplied cable ties when you believe that it has been filled to
a suitable level. Another cable tie is used a little further up. This forms the bottom of
the next bag. The filled bag is then cut off, and the machine is ready to be used again.
