Cleaning
56
1. Inspect accessible cooling fins and clean with
compressed air or backpack blower as need-
ed. If the buildup is excessive, refer to step 2.
2. If the debris cannot be removed with com-
pressed air, it will be necessary to remove the
engine from the chassis and remove the en-
gine shroud for thorough cleaning. See your
authorized Briggs & Stratton dealer for this
service.
CAUTION
DO NOT use a pressure washer to clean
the cooling system on an air-cooled en-
gine; mud may form under the cooling
shroud on the cylinder head and cooling
fan resulting in engine overheating.

IMPORTANT:
Yearly, it is good maintenance prac-
tice to remove the engine cooling shroud and clean
the cylinder head cooling fins thoroughly to prevent
overheating and extend engine life. Make sure
cooling shroud is reinstalled properly. This proce-
dure will require removing the engine from the
chassis.
