4.4.1 Change oil and oil filter
The oil and oil filter shall be changed periodically to remove the pollutants suspended in the oil, because the oil will
become dirty and the oil additives will decrease with engine operation.
Change oil filter
Run the engine and stop it when the coolant temperature reaches 60℃. Clear
stains around the oil filter. Use suitable socket to hold upper part of the filter to
remove the spin type oil filter (it is difficult to remove the filter with a common
spanner for it will deform the filter). Change the oil filter.
Screw the new fuel filter until the O-ring contacts the sealing surface of the filter
head and then further screw the filter to 45–60 N·m, or by 3/4-1 turn.
△Caution: Before installing the new filter, apply a layer of clean oil on the
surface of the O-ring on the filter.
