Avoid vibrations. Do not stopthe Lavina® X on one spot while the tools are still working because they will leave marks on the floors’ surface. When working wet,first choose the water tap (Fig.4.2) and the position for the water feed, periodically start to pump and release water onto the floor’ssurface (Fig.4.6 Pos.6). When working dry, check the floor’s surface periodically to ensure that dust is not accumulating on thesurface, also check regularly to make sure your vacuum is working properly.STOPPING THE MACHINEThe stopping of the machine must be done gradually until the motor stops.
