AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air fi lter.
Clean the element after every 25 hours
of operation or every season. Replace
the air fi lter every 100 hours of operation
or every season, whichever occurs fi rst.
Service air cleaner more often under dusty
conditions. See the maintenance section
of your engine manual.

Inspect and replace corroded muffl er as it
could create a fi re hazard and/or damage.
IN-LINE FUEL FILTER (KOHLER or B&S
PRO / ENDURANCE ENGINES ONLY)
The fuel fi lter should be replaced once
each season. If fuel fi lter becomes
clogged, ob struct ing fuel fl ow to car bu re-
tor, re place ment is re quired.
1. With engine cool, remove fi lter and plug
fuel line sec tions.

CLEANING
IMPORTANT: For best performance, keep
mower housing free of grass build-up and
trash. Clean the underside of your mower
after each use.
• Clean the underside of your lawn mower
by scraping to remove buildup of grass
and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
• Keep fi nished surfaces and wheels free
of all gasoline, oil, etc.
We do not recommend using a garden
hose to clean the outside of your lawn
mower unless the elec tri cal system, muf-
fl er, air fi lter and carburetor are covered to
keep water out. Water in engine can result
in shortened engine life.
GRASS CATCHER (IF SO EQUIPPED)
Grass catcher may be hosed with water
but must be dry when used.
CAUTION: Under nor mal usage, the
catch er material is subject to de te ri o ra tion
and wear and should therefore be checked
to ensure compliance with origi nal
manufacturer specifi cations.
