244SERVICING AND MAINTENANCE
RUBBER HOSES
As far as the brake system and fuel rubber hoses are con-
cerned, follow the “Scheduled Servicing Programme” in
this chapter carefully.
Ozone, high temperatures and prolonged lack of fluid in
the system may cause hardening and cracking of the
hoses, with possible leaks. Careful checking is therefore
necessary.
WINDSCREEN/REAR WINDOW
WIPER
BLADES
Periodically clean the rubber part using special products;
TUTELA PROFESSIONAL SC 35 is recommended.
Replace the blades if the rubber edge is deformed or worn.
In any case, it is advisable to replace them approximately
once a year.
A few simple precautions can reduce the possibility of
damage to the blades:
❍make sure that the rubber part is not frozen to the
windscreen in sub-zero temperatures. Use an an-
tifreeze product to release it if required;
❍remove any snow from the glass: in addition to pro-
tecting the blades, this prevents effort from the motor
and overheating;
❍do not operate the windscreen and the rear screen
wipers on dry glass.
Driving with worn wiper blades is a seri-
ous hazard, because visibility is reduced
in bad weather.
