MAINTENANCE
NB
• Read the instructions in advance and make sure that all the requisite tools are available�

is essential in order to ensure safe, cost-effective and problem-free operation and also
contributes to reduced emissions�
• It is impossible to mitigate for all possible risks that may arise during maintenance work� Only
the user himself/herself can decide whether or not a particular measure should be carried out�
• Follow the recommendations and the inspection and maintenance schedule given in the
operation instructions� Remember that the schedule assumes that the engine is used for its
intended purpose� Operating the engine with a high load or at a high temperature for extended
periods of time, or operating it in damp or dusty environments requires more frequent
maintenance�
• Incorrect maintenance of the engine or failure to correct faults before use may create a risk of
personal injury or death�
• In order to ensure the best possible quality and level of reliability, only new original parts (or
equivalent) must be used when carrying out repairs or replacing components�
