TROUBLE SHOOTING GUIDE
1. INSUFFICIENT WATER ON TO THE BRUSH
4.
Check that the cock is open (signal lamp on).
5.
Check that there is water in the solution tank.
2. MACHINE DOES NOT CLEAN WELL
6.
Check the condition of the brushes and replace if necessary (brushes must be replaced when bristles
are 15 mm. high).
7.
Check that brush pressure is sufficient. Increase as necessary using lever (1).
8.
Use another type of brush rather than the standard brush. We recommend, to clean floors with
exceptionally difficult dirt, the use of special brushes that are supplied on request and according to
your specific needs (see "BRUSH SELECTION AND USE" below).
3. SQUEEGEE DOES NOT DRY PERFECTLY
1.
Check that the squeegee is clean.
2.
Check all adjustments (see "PREPARING THE MACHINE").
3.
Clean the entire aspiration unit (see "DAILY MAINTENANCE"). .
4.
Replace worn rubbers.
4. SUCTION MOTOR DOES NOT WORK
1.
Check if the suction motor switch (1) is ON. Check if the main key switch is ON.
2.
Check if the recovery tank is full.
5. TOO MUCH FOAM FORMATION
1.
Check that low-foam detergent is used. Add, if necessary, a small quantity of anti-foam liquid to the
recovery tank.
Remember that more foam is generated when the floor to be cleaned is not very dirty. In this case use a
more diluted detergent solution
