(OPTION)
Figure 3-2. Air Cleaner Components.
NOTE: Damaged, worn, or loose air cleaner com-
ponents could allow unfiltered air into the engine
causing premature wear and failure. Replace all
damaged or worn components.
CLEAN AIR INTAKE/COOLING AREAS
To ensure proper cooling, make sure the grass
screen, cooling fins, and other external surfaces
of engine are kept clean at all times. Every 50
operating hours (more often under extremely
dusty, dirty conditions), remove the blower hous-
ing and other cooling shrouds. Clean the cooling
fins and external surfaces as necessary. Make
sure the cooling shrouds are reinstalled. Refer to
the "Disassembly" and "Reassembly" sections for
cooling shroud removal and installation proce-
dures.
NOTE: Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or cool-
ing shrouds removed will cause engine damage
due to overheating.
CHECK SPARK PLUG
Every 1 00 operating hours, remove the spark plug,
check its condition, and reset gap or replace with
new plug as necessary. Refer to Figure 3-3.
