When working on a hydraulic piping 1 the engine has to be stopped, and it is essen-
tial that instructions 0520−1 ’Exchange of a defective hydraulic piping’ in the Oper-
ating Manual be strictly followed.
Before beginning dismantling works recheck whether the servo oil system is
pressureless and properly drained by means of carefully opening drain screw 8
and screw plug 9.
