Bona Belt
The Bona Belt sanding machine makes big jobs seem small. The compact design
makes the machine simple to manoeuvre and easy to transport. It can be disassembled
and reassembled quickly and easily. The Bona Belt has a very efficient dust pick up,
leaving a cleaner floor. For optimal dust reduction, the Bona Belt is compatible with the
Bona DCS 70 (Bona Dust Containment System).
Suitable for sanding all kinds of timber and parquet floors, the Bona Belt is a machine for
all occasions.
•Unique construction gives a choice of a 250 mm or 200 mm drum
•Ergonomically designed handle allows fingertip control to raise and lower the drum.
•Large front and side covers make the drum and tension roller easy to reach.
•Very efficient dust pick up
•A compact design gives excellent manoeuvrability
•Easy to transport due to the quick breakdown of the machine

For further more detailed technical data please see the machine manual.
When using the Bona Belt for the first time, read the machine manual carefully and
follow the instructions to set the machine up.
Check that the sanding drum is raised and connect the cable to the power socket. For
your own safety - always use an earth leakage circuit breaker.
Start the machine and let it run for a few seconds so that the dust bag is filled with air
and the motor reaches full speed. You will note that the motor sound changes during
this time as the Easy start system operates to prevent high load on the motor during the
start-up process.
At this point, check that the sanding belt is adjusted properly. If required use the fine
adjustment screw on the housing above the drum to centre the sanding belt. Close the
front and side access panels firmly. Adjust the drum pressure as required using the
adjustment handle at the rear of the machine. In general terms the coarser the abrasive
being used the higher the drum pressure required.
Vacuum the floor properly between each sanding operation so that it is clean before
continuing. Whilst the dust collection system on sanding machines is efficient, the
possibility of dust or abrasive particles remaining on the floor exists. The use of sanding
machines on a poorly cleaned floor can push these particles into the surface of the
timber causing issues with discolouration.
If there is any damage to the floor that needs to be repaired or nail holes are to be filled,
these operations should be completed during the sanding process using Bona Mix&Fill
or a proprietary filler. It is not recommended to apply filler after the application of a Bona
primer.

For optimal dust collection the Bona DCS 70 (Bona Dust Containment System) should
be used. If using the machine with a dust bag then Bona's original dust bags should be
used. During the sanding process the dust bag should be emptied when filled to one
third of its size; Use a face mask min class P2. Failure to empty the dust bag at the
appropriate time will result in a loss of efficiency and reduced dust pick up.
Sanding dust, particularly where the timber flooring had been previously coated with
solvent based products or oils, may spontaneously combust. After each sanding
operation, the dust bag should be emptied. Do not store any sanding machine with an
un-emptied dust bag. All sanding dust removed from the machine must be kept
outdoors due to the potential fire hazard.
It is recommended that the machine is serviced every 250 hours or once a year by a
professional machine / electrical workshop. However, regular maintenance should be
carried out by the operator.
The power cable should be checked for damage frequently. If the motor receives a
weak power supply, e.g. from poor supply or an over long cable or for other reasons
becomes overloaded, the overload protection will be triggered. N.B. Prior to restarting
the motor it must be allowed to cool down.
The sanding drum and tensioning system must be cleaned regularly. Wheels should be
kept clean and replaced if worn; irregular wheels can cause irregular unsatisfactory
sanding.
