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.
Refer to Figure 3-5.
Every 50 operating hours (more often under extremely
dusty, dirty conditions), remove the blower housing
and other cooling shrouds. Clean the cooting fins and
extemal surfaces as necessary.
Make sure the cool-
ing shrouds are reinstalled.
Refer to the "Disassembly" and "Reassembly" Sec-
tions for cooling shroud removal and installation
procedures.

Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or
cooling shrouds removed will cause engine
damage due to overheating.
