BLADES
Periodically clean the rubber part using spe-
cial products; TUTELA PROFESSIONAL
SC 35 is recommended.
If the rubber blades are bent or worn they
should be replaced. In any case they should
be changed once a year.
A few simple notions can reduce the pos-
sibility of damage to the blades:
– If the temperature falls below zero,
make sure that ice has not frozen the rub-
ber against the glass. If necessary, thaw us-
ing an antifreeze product.
– Remove any snow from the glass: in ad-
dition to protecting the blades, this prevents
effort on the motor and overheating.
– Do not operate the windscreen and
rearscreen wipers on dry glass.
RUBBER HOSES
As far as the brake system and fuel sup-
ply rubber hoses are concerned, carefully fol-
low the Scheduled Maintenance Programme
of this chapter. Indeed, ozone, high tem-
peratures and the prolonged lack of fluid in
the system may cause hardening and crack-
ing of the hoses, with possible leaks. Care-
ful control is therefore necessary.
Do not cross switch the
tyres, moving them from
the right of the car to the left and
vice versa.
WARNING
Alloy rim painting involving
temperatures exceeding
150°C should be avoided since
wheel mechanical characteristics
could be impaired.
