2. Take all necessary steps to ensure that the device is in a safe condition (see " MACHINE SAFETY ’”).
ATTENTION : users are advised to always wear protective gloves, to avoid the risk of serious
injury to hands.
3. Remove the vacuum hose (1) from the vacuum nozzle (2) on the squeegee body ( Fig.1 ).
4. Remove the vacuum tube (1) via the hole on the back of the recovery tank ( Fig.2 ).
5. Remove the recovery tank drainage hose from the clamps.
6. Rinse the inside of the vacuum hose with a jet of running water.
7. Repeat the operations in reverse order to reassemble all the parts.
ATTENTION : Use particular caution when placing the vacuum hose behind the lifting chain, as
indicated on the label ( Fig.3 ).
CLEANING THE WATER SYSTEM
