Changing the Engine-Oil Filter
Note:
Change the engine-oil filter more frequently when
operating conditions are extremely dusty or sandy.
1. Drain the oil from the engine; refer to Changing the
Engine Oil (page 33) .
2. Place a rag under the oil filter to soak up any spilled oil.
Important:
Spilled oil may drain under the engine
and onto the clutch. Oil spilled on the clutch may
damage the clutch, cause the blades to stop slowly
when the clutch is in the O
FF
position, and cause
the clutch to slip when the clutch is switched to
the O
N
position. Wipe up any spilled oil.
3. Change the engine-oil filter ( Figure 39 ).

4. Fill the crankcase with the proper type of new oil; refer
to
Changing the Engine Oil (page 33) .
