3. When changing the oil filter, use the following instructions:
A) Locate oil filter (Figure 8-4).
B) Place a suitable container beneath the oil filter and turn
the filter counterclockwise to remove the filter.
C) Coat the gasket of a new filter with engine oil. Turn
the new filter clockwise until the gasket contacts the
filter adapter, then tighten an additional 3/4 turn.
4. Remove the oil fill cap and insert a clean funnel into the
oil fill opening. Fill the crankcase with the recommended
oil until the oil level is at the full point on the dipstick.
Approximately 2030 ml (2.1 qt.) are required when chang-
ing the oil and oil filter. POUR SLOWLY.
5. When the crankcase is filled to the proper level, install the
oil fill cap. Start engine to fill oil filter, recheck/correct oil
level.
OIL COOLER:
Some engines are equipped with an oil cooler. The oil cooler
is mounted on the blower housing. Forced air from the flywheel
fan flows through the oil cooler fins dissipating heat from the
engine oil.
The oil cooler fins should be cleaned every 100 hours and
checked periodically for debris and cleaned with compressed
air or a soft bristle brush.
