VACUUM CONNECTION 

   Lavina®B21-E has a system for dust collection in a vacuum bag using the stream of the air flow produced by the tool.  
Additionally an electrical vacuum is mounted and connected to the dust collection system. The machine is working either with or 
without an electrical vacuum cleaner.   In case of need there is a possibility to connect a hose Ø50,8mm/2in of another vacuum 
cleaner. 

Do not switch on the vacuum cleaner when working on wet floor!
