REPLACING THE FRONT SQUEEGEE RUBBER
Suction will be poor and the machine will not dry perfectly if the front squeegee rubber is worn. Proceed as
follows to replace:
1.
Make sure the brush head unit is in its working position (if necessary, turn the I-DRIVE selector to the
“Transfer” position to raise both the brush head and the squeegee)
2.
Check the electric system connector is disconnected from the battery connector (for battery versions)
or from the generator connector (for versions with a combustion engine)
3.
Make sure the main switch is in the "0" position. If it is not, turn the key a quarter turn to the left
4.
Check the parking brake is engaged. If it is not, engage it by means of the lever (1)
5.
Disconnect the squeegee by loosening the knobs (2)
6.
Loosen the rubber-pressing blade securing screws (3)
7.
Remove the rubber-pressing blade (4), then the rubber, for replacement
8.
To replace the rubber, proceed in reverse order
WARNING: These operations must be carried out using gloves to protect
against contact with dangerous solutions.
