RECOMMENDATIONS - PRECAUTIONS : MA TYPE PILOTED MANUAL GEARBOX
Safety requirements
ESSENTIAL : Given the special features of the MA type piloted
manual gearbox, observe the requirements detailed below.
IMPERATIVE : Always disconnect the battery negative terminal
before operating on the actuators.
NOTE : After disconnecting the battery, never try to remove the clutch
actuator on the vehicle before having checked that it is in the closed
position.(rod pushed in).
IMPERATIVE : After Sales checks done with the engine running must
be performed with «Neutral» engaged and the handbrake on (unless
there is a clear mention otherwise in the repair procedures)
IMPERATIVE : The areas of movement of the clutch fork and of the
gear engagement lever must always be kept free during the actuator
operating phases.
IMPERATIVE : When initialising the clutch actuator and/or gearbox
actuator, do not allow any person to walk or stand in front of the
vehicle.
WARNING : When the engine is running, it is forbidden to perform
repairs on the clutch and gearbox actuators on the vehicle (whether
manually or using a diagnostic tool).
WARNING : Each time the driver's door is opened and each time the
igntion is switched on, the gearbox ECU prompts the initialising of the
clutch and gearbox actuators (there is movement of the clutch fork and
of the gear lever).
WARNING : Whether the ignition is switched on or not, an action on
the gear selector causes the clutch to move and the gear engagement
lever to move on the gearbox.
