:
The handling of the brushes operation
must be carried out using suitable gloves
to protect both mechanically 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 sup-
port by rotating the lever (2) counterclock-
wise and making slide the stud bolts (1) in
their slots up to their release.
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
REAR SQUEEGEE RUBBER RE-
PLACEMENT
Check the squeegee rubber wear and
eventually turn or replace it.
For the replacement it is necessary to:
1. Lift the squeegee acting upon the lever
(fig. 1, pos. 16).
2. Uncouple the hook (1) of the rubber
holder blade, release the extremities (2)
from the squeegee body and take off the
rubber (4).
3. Turn the rubber (4) to a new side or
replace it.
To reassemble the squeegee reverse the
operations above, inserting the rubber (4)
on the guides (3), couple the extremities
(2) of the rubber holder blade onto the
squeegee body and finally block the hook
(1).
SQUEEGEE HOSE CLEANING
Weekly or in case of insufficient suction,
it is necessary to check that the squeegee
hose is not obstructed. Eventually, to clean
it, proceed as follows:
1. Take off the hose from the squeegee
coupling (1) and release the guide spring
of the squeegee hose (2).
2. Wash the inside of the hose with a water
jet, from the squeegee hose side.
3. To reassemble the hose reverse the
operations above.

place for tanks draining.
2. Unscrew the solution tank cap (1).
3. Unscrew the exhaust plug (2).
3a. The machines equipped with the op-
tional device of the solution drainage, it is
sufficient to open the solution valve of the
device (see under "EMPTYING DEVICE
