TROUBLESHOOTING
52. INSUFFICIENT WATER ON THE BRUSHES
1.
Check there is water in the solution tank
2.
Check that the water/detergent solution release adjustment lever (1) is open
3.
Check that the water/detergent selectors (2-3) are open (for CDS versions only)
4.
Clean the solution filter located at the front of the machine.
53. THE SQUEEGEE DOES NOT DRY PERFECTLY
1.
Check the squeegee is clean.
2.
Check the regulation of the squeegee (see “MACHINE PREPARATION”).
3.
Clean the entire suction unit (see “WEEKLY MAINTENANCE”).
4.
Replace the rubbers, if worn.
54. THE BRUSH HEAD COVER DOES NOT DRY PERFECTLY
1.
Check that the suction nozzle in the brush head cover is not obstructed
2.
Check that the settings for the brush head cover are correct
3.
Clean the entire suction unit (see “WEEKLY MAINTENANCE”).
4.
Replace the rubbers, if worn.
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
Verify that a low foam detergent has been used. If necessary, add a small quantity of antifoam 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 switch on the suction cap (see also “CLEANING THE RECOVERY TANK” in the
chapter “DAILY MAINTENANCE”).
58. THE BRUSH MOTOR DOES NOT WORK
ATTENTION To avoid damaging the floor, the motor only starts up when the machine is moved forwards
1.
Check that the base 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 motor to the terminal under the footboards.
