TROUBLESHOOTING
1.
ELECTRICAL SYSTEM SAFETY
The machine is fitted with self-restoring safety fuses located in the electric system *beneath the solution
tank) that interrupt the power supply to the brush and suction motors when the machine exceeds the
pre-determined load. To restore the power supply to the motor, switch off the machine and wait for the
fuses to cool down (about 40 seconds). If the switch disconnects the current several times in a row,
contact the APEC technical assistance centre.
2.
INSUFFICIENT WATER ON THE BRUSHES
1. Verify that the solution tank filter is clean.
2. Verify that the solenoid valve switch is on.
3. Verify that the quick connection is correctly inserted.
4. Check the cock regulation screw on the water outlet.
3.
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 15mm long.
4.
THE SQUEEGEE DOES NOT DRY PERFECTLY
1. Check the squeegee rubbers are clean.
2. Check the suction tubes are correctly inserted in their housing on the squeegee.
3. Check the distributor is clean.
4. Replace the rubbers, if worn.
5.
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.
