blocking levers (2).
4. Take off the filter and filter protection.
5. Rinse the tank with a water jet.
ATTENTION:
This operation must be carried out using gloves to
protect from contact with dangerous solutions.
SUCTION FILTER CLEANING
1. Take off suction cover (1) after rotating the
blocking levers (2).
2. Take off the filter and filter protection.
3. Clean all parts with a water jet especially inside
surfaces and filter bottom.
4. Carry out carefully the cleaning operations.
5. Reassemble all parts.
AFTER
BRUSH/ES CLEANING
Disassemble the brushes and clean them with a wa-
ter jet (for the disassembly see as follows under
"BRUSHES DISASSEMBLY").
BRUSHES DISASSEMBLY (ruby 45t, ruby 55t)
1. Lift the brushes base lowering the pedal (10).
2. Switch off the machine acting upon the general
switch (12). For machines equipped with key switch
(see under "OPTIONAL ACCESSORIES"), turn the key
counterclockwise.
3. With the brushes base in lifted position, turn the
brush in its rotating sense, until it is released from
the brush holder plate seat as indicated in the figure.
The following figure shows the rotating sense for
brushes release on the models ruby45t and ruby55t.
ATTENTION:
The execution of brushes disassembly operations
with electric supply on, may cause damages to hands.
AUTOMATIC BRUSH DISASSEMBLY (ruby 50t, ru-
by 50bh)
1. Lift the brush base lowering the pedal (10).
2. Act upon the levers drive control (7) and simul-
taneously press the push button (11) of the brush re-
lease. In this way the brush is uncoupled automati-
cally.
3. Release the push button and the levers.
4. Switch off the machine acting upon the general
switch (12). For machines equipped with key switch
(see under "OPTIONAL ACCESSORIES"), turn the key
counterclockwise.
The handling of the brushes operation must be car-
ried out using suitable gloves to protect both me-
chanically from contact with the bristles and the
chemical risk of contact with dangerous solutions.
SQUEEGEE CLEANING
Keeping the squeegee clean guarantees always the
best drying action.
For the cleaning it is necessary to:
1. Take off the squeegee hose (3) from its coupling.
2. Disassemble the squeegee from its support by ro-
tating the lever (2) counterclockwise and making
slide the stud bolts (1) in their slots up to their re-
lease.
3. Clean with care the internal part of the squeegee
inlet eliminating eventual dirt residuals.
4. Clean with care the squeegee rubbers.
5. Reassemble all parts.
WEEKLY MAINTENANCE
