The machine has 9 access doors for maintenance. The doors and covers are partly fitted with lock up handles, partly secured by screws.

For safety reasons, the locks integrated in the handles 4 must be unlocked before starting to work with the machine.

The radiator hood 32 and the middle cover 33 are screwed parts whose opening is not necessary in the limits of usual maintenance works.
