TROUBLESHOOTING
INSUFFICIENT WATER ON THE BRUSH
1. Check the tap – located beneath the symbol – (1) is turned on.
2. Check there is water in the solution tank.
3. Check that the solution tank filter cartridge is clean
THE MACHINE DOES NOT CLEAN WELL
1. Check the state of wear and tear of the brush and, if necessary, replace it (the brush must be replaced
when the bristles are about 15mm long).
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”).
THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check the squeegee rubbers are clean.
2. Adjust the inclination of the squeegee (see "SQUEEGEE" under “MACHINE PREPARATION”).
3. Check the suction tube is correctly inserted in its housing on the recovery tank.
4. Check the inner filter of the recovery tank is not dirty and, if necessary, clean it thoroughly.
5. Disassemble the entire suction unit and clean it.
6. Replace the rubbers, if worn.
7. Check the suction motor switch is turned on.
8. Check wheel adjustment.
EXCESSIVE FOAM PRODUCTION
Check 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.
ELECTRIC FUSES AND THERMAL CUT-OUTS
The machine is fitted with the following electrical protection systems:
Power fuses arranged in the electrical box, to protect against short-circuiting
thermal trip units arranged on the outside of the handlebars, to protect the following motors:
1. 30 A trip unit for squeegee
2. 20 A trip unit for suction motor
3. 50 A trip unit for brush head motor (SMX 60S version)
In the event of malfunctioning, check a thermal cut-out has not intervened. If the motor overheats, its
thermal cut-out intervenes to block the electricity supply. Wait a few minutes until it has cooled down, then
press the specific trip unit button to reactivate the power supply and motor operation.
