- 37 - 29z
12.1 Refer to the following chart for routine maintenance actions. Refer to the excellent Maintenance
Schedule and instructions beginning on page 63 of the D4/D6 VOLVO engine manual for complete
instructions on each item. Perform all maintenance once a year even if hour levels have not been
reached. Some of the items you may choose to leave to professionals, but many you can do yourself. In
particular, it is a good idea to have a certified mechanic perform check-ups from time to time on the
engine, generator, and any other key equipment installed onboard. Volvo & Northern Lights engines are
assumed – check your manuals if your brands differ.
