8.2.2 Maintenance plan
In new and generally overhauled engines, after 25 operating hours:
▪ Change the engine oil
▪ Check the tappet clearance and adjust if necessary
▪ Check the screw connections (do not retighten the screws for attaching
the cylinder head)
In case of a low number of operating hours, change the engine oil no later
than every 12 months, regardless of the actual number of operating hours.
The interval at which maintenance work should be performed on the fuel fil-
ter depends on the cleanliness of the fuel in use and may need to be short-
ened to 250 operating hours.
