Respect the precautions to be taken when
operating on a vehicle.
The flexible pipe must not come into contact
with corrosive products.
Do not distort the flexible pipe by more than20°
angular (X), 20mmaxial, 25 mmshear(Y)
(flexible pipe not fitted).
Do not distort the flexible pipe by more than3°
angular (X), 0 mmaxial, 3 mmshear
(Y) (flexible pipe in place).
WARNING : Non-respect for these precautions
will result in a reduction in the lifetime of the
flexible pipe. It is thus essential to disconnect or
remove the exhaust line in any operation
necessitating the lifting of the power unit.
