Dust Extraction
Dust which occurs during your work is hazardous to health. That is why the
EBS 125.4 O/RO
must be used with a vacuum cleaner, and a dust mask
has to be worn. The suitable Wet/Dry Vacuum Cleaner DSS 25 A / DSS 50
A / DSS 35 MiP is available as accessory. It can directly be attached to the
connection on the dust hood.
Changing the brush rim
If the length of the brushes is – due to wear - smaller than 5 mm (extreme
formation of dust during grinding), the brush rim has to be replaced
completely.
