Check that the edges (5, Fig. D) of the front and rear
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.
3.
Check that the front and rear rubbers (3 and 4, Fig. D)
are integral and free from cuts and tears; otherwise
replace them as described below. Check that the front
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).
5.
Connect the vacuum pipe (25, Fig. C) to the
squeegee (10).
