1) Oil change intervals vary, depending on oil grade and sulfur content of the fuel. Please refer to page 56.
2) Change the filters during each oil change.
3) If the fresh water system is filled with a rust protection mixture, it must be changed every year. On the
other hand, if the fresh water system is filled with anti-freeze (glycol mixture), it must be changed every
second year.
4) IMPORTANT! In operation situations where the number of forward-reverse operations averages
more than 20 per hour, the oil should be changed every 100 hours.
