FAULT DIAGNOSIS
The Machine Does Not Clean Properly

assistance.
2. The brushes bristles have gotten worn. Check the brushes wear condition

bristles have reached a height of about 1/2" (15 mm). To replace the brushes,
see instructions at paragraph "BRUSHES DISASSEMBLY" and "BRUSHES
ASSEMBLY".
3. The detergent solution is insufficient: adjust the solution valve.
4. Check that the liquid detergent is in the recommended percentage.
5. Increase the brushes pressure (see at paragraph "ADJUSTMENT OF THE
BRUSHES PRESSURE").
Contact the authorized technical assistance for advice.
The Squeegee Does Not Dry Perfectly
1. Check that the squeegee rubbers are clean.
2. Check the adjustment of the height and the inclination of the squeegee (see
section "ADJUSTMENT OF THE SQUEEGEE" in "BEFORE USE").
3. Check that the suction hose is correctly inserted in the proper seat on the
recovery tank and that it is not obstructed.
4. Clean the suction filter.
5. Replace or turn the rubbers if worn out.
6. Check on the display that the starting signal of the suction motor is on.
Excessive Foam Production
Check that low foam detergent has been used. If necessary, add small quantities of
anti foam liquid into the recovery tank.
Please be aware that a bigger quantity of foam is produced when the floor is not
very dirty. In this case please dilute detergent solution.
