service with engine and blade running. STOP engine

HOT. Avoid serious burns, allow sufficient time for all
components to cool.
1. Drain the fuel tank completely.
2. Remove the dipstick (A, Figure 14), then turn the
mower on its side. Allow the oil to drain from the oil
fill tube into an appropriate container. Dispose of

engine oil to the 'full' mark on the dipstick. Refer
to the section entitled 'Oil Recommendations'. Do
not overfill.

IMPORTANT: Drain the fuel tank before tipping the
machine. DO NOT tip the machine with the carburetor
or spark plug down. Oil from the crankcase will satu-
rate the air filter and cause the engine to be hard to
start or not start at all. If contamination does occur, the
air filter will have to be replaced.

Change Oil Filter (if equipped)

1. Drain the oil from the engine. Refer to the section
entitled 'Change Engine Oil'.
2. Remove the oil filter (B, Figure 14) and dispose of
properly.
3. Before you install the new oil filter, lightly lubricate
the oil filter gasket with fresh, clean oil.
4. Install the oil filter by hand until the gasket contacts
the oil filter adapter, then tighten the oil filter 1/2 to
3/4 turns.

check for oil leaks.

Service Air Filter

!
Never start or run the engine with the air cleaner
assembly (if equipped) or the air filter (if equipped)
removed.
NOTE: Do not use pressurized air or solvents to clean
the filter. Pressurized air can damage the filter and
