2. Verify that the PAD is intact.
3. To replace the pad, see under “PAD DISASSEMBLY”
and “PAD ASSEMBLY”.
4. The solution detergent is insufficient: open more
the solution valve.
5. Check that the liquid detergent is in the
recommended percentage.
6. Increase the base pressure (see at paragraph
"ADJUSTMENT OF THE BASE 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.
4. Clean the suction filter.
5. Replace the rubbers if worn out.
