Remove oil drain plug and drain oil while engine is still
warm, Figure 1-4. Change oil filter (Figure 1-5) and replace
drain plug.
Remove dipstick and refill slowly with new oil of proper
service classification and viscosity grade. Refill to full mark on
dipstick. When checking oil level, dipstick must be all the way
in for accurate readings.

Replace oil filter every 100 hours. Before installing new filter,
lightly oil filter gasket with fresh clean engine oil. Screw filter
on by hand until gasket contacts filter adapter. Tighten 3/4 to
one full turn farther, Figure 1-5.

CLEANING INTAKE SCREEN:
Grass particles, chaff or dirt can clog the air cooling system,
especially after prolonged service in cutting dry grass or when
operating in extremely dusty or dirty conditions. Continued
operation with a clogged cooling system can cause severe over-
heating and possible engine damage. Figure 1-6 shows the areas
to be cleaned. This should be a regular maintenance operation,
or clean intake screen and oil cooler fins after each use.
