For transport in lifts, the applicable user and safety instructions must be followed, especially where load capacity is concerned. In order to prevent unauthorized use of the machine, it must always be stored in a suitable location. Regularly check the power cable and the machine for wear or aging.

Assembling the dust skirt
Place the dust skirt in the intended notch on the rubber strip.
Never use the dust skirt when staining or oiling.
Always remove the skirt when transporting the machine.
Attaching dust containment
Attach the dust containment hose to the dust tube on the Bona FlexiSand DCS ® Buffer. If using Bona DCS ® , connect DCS cuff to dust tube and fasten with provided clamp.
Attaching a vacuum cleaner
For minimized dust environment use a vacuum cleaner intended for wooden dust. Attach the vacuum cleaner's hose to the 38mm tube on the Bona FlexiSand DCS ® Buffer.
The airflow on the vacuum cleaner should be at least 245m 3 /h. We strongly recommend the Bona DCS ® for the best results.

If you have not operated a Bona FlexiSand DCS ® Buffer previously, ensure that no one or nothing is nearby before you start the machine.
