Cooling Air Intake System
To prevent engine overheating and possible engine
damage, clean grass clippings, chaff, and dirt from
the rotating engine air intake screen after every 8
hours of operation. In certain mowing conditions
(dry grass, leaves, tree “cotton”, etc.), it may be nec-
essary to check and clean this area several times
each day to prevent engine overheating. Also, visu-
ally check inside cylinder head shroud and between
cylinder head ns for material packed in this area
which would prevent cooling airow; remove shroud
and clean as required.
CAUTION
Operating the engine with a blocked air
intake screen, dirty or plugged cooling
ns, and/or cooling shrouds removed will
cause engine damage from overheating.
