rubbers (12) lay down on the same level, along all
their length; otherwise adjust their height as follows:
– disengage the retainer (6) and loosen the wing
nuts (7) to adjust the rear rubber (4); then tighten
the wing nuts and engage the retainer.
– loosen the nuts (8) to adjust the front rubber (3);
then tighten the nuts.

corner (9) of the rear rubber is not worn; otherwise,
overturn the rubber to replace the worn corner with an
integral one. If the other corners are worn too, replace
the rubber as follows:
– To replace (or overturn) the rear rubber (4)
disengage the retainer (6), unscrew the wing nuts
(7) and the retaining strip (10). Install in the
reverse order of removal;
– To replace the front rubber (3) remove the nuts (8)
and the retaining strip (11). Install in the reverse
order of removal.
After the rubber replacement (or overturning),
adjust their height as described at the previous
step.
4. Reinstall the squeegee assembly (10, Fig. C) in the
correct position and screw down the knobs (11).

open the screen (1); recover the float (3), clean all the
components and then reinstall them.
5. Check that the tank cover gasket (7, Fig. E) is
integral.
If necessary, replace the gasket (7) after removing it from
its housing (8). When assembling the new gasket, install
its joint (9) in the central area as shown in the figure.

gauze (2), clean and reinstall them on the support (3).
CAUTION!
It is advisable to use protective gloves when
cleaning the brush because there can be
cutting debris.
NOTE
The gasket (7) creates vacuum in the tank for
recovery water vacuuming.
NOTE
The hole (1, Fig. E), allowing to compensate
the air in the cover interspaces, contributes
to create vacuum in the tank.
NOTE
The wire gauze (2) must be correctly
positioned on the support (3) housing (4).
