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 than 3°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..
