55.
THE MACHINE DOES NOT CLEAN WELL
1.
Check the state of wear and tear of the brushes and, if necessary, replace them. The brushes should
be changed when the bristles are about 15 mm long. To replace them, see “REPLACING THE
BRUSHES”, or “DISASSEMBLING THE BRUSHES” and “ASSEMBLING THE BRUSHES”. Working
with over-worn brushes may cause damage to the floor.
2.
Use a different kind of brush to the one fitted as standard. For cleaning floors where the dirt is
particularly resistant, we recommend the use of special brushes supplied upon request and according
to needs (see “CHOOSING AND USING THE BRUSHES”).
56.
EXCESSIVE FOAM PRODUCTION
Check that a low foam detergent has been used. If necessary, add a small quantity of anti-foam liquid to
the recovery tank.
Remember that, when the floor is not very dirty, more foam is generated. In this case the detergent solution
should be more diluted.
57.
THE VACUUM CLEANER DOES NOT FUNCTION
1.
Check whether the recovery tank is full and, if necessary, empty it
2.
Check the float on the vacuum cap (see also “CLEANING THE RECOVERY TANK” in the paragraph
“DAILY MAINTENANCE”)
58.
THE BRUSH MOTOR DOES NOT WORK
ATTENTION To avoid damaging the floor, the engine only starts up when the machine is moved forwards
1.
Check that the brush head is lowered during start-up
2.
The operator must be properly seated in the driving position
3.
Check no thermal protection device has intervened.
4.
Check the correct connection of the engine to the terminal board under the footboards.
