3.1 When performing maintenance work
DANGER
Risk of injury and scalding!!
Therefore:
S Carefully read the safety regulations in the Operating Instructions!
NOTE
No liability for engine damage if non-approved spare parts are used.
Therefore:
S Use only genuine MAN spare parts. MAN will accept no responsibility for damage resulting from the
installation of other parts from external sources.
S Exchange worn seals.
S Tighten screwed connections for which tightening torques are specified (see “Service Data"), always
using a torque wrench.
S Clean removed parts before refitting them, and check them for damage unless exchange is mandatory.
3.2 When checking the engine oil level or changing the engine oil
