valve.
4.
Check that the liquid detergent is in the recommended
percentage.
5.
Increase the brushes base 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
