SQUEEGEE CLEANING

NOTE
The squeegee must be clean and its blades must be in good conditions in order to get a good drying.

It is advisable to wear protective gloves when cleaning the squeegee because there may be sharp debris.
1. Drive the machine on a level floor.
2. Make sure that the power supply cable plug is disconnected from the electrical mains.
3. Lower the squeegee (21) with the lever (7).
4. Loosen the handwheels (22) and remove the squeegee (21).
5. Disconnect the vacuum hose (10) from the squeegee.
6. Wash and clean the squeegee (Fig. 4). In particular, clean the compartments (A) and the vacuum hole (B) from dirt and debris.
Check the front blade (C) and the rear blade (D) for integrity, cuts and tears; if necessary replace them (see the procedure in
the following paragraph).
7. Install the squeegee in the reverse order of removal.

blade (D).
• Install the blade in the reverse order of removal.
