CUSTOMER RESPONSIBILITIES
Every 100 hours of operation (more often under
extremely dusty, dirty conditions), remove the
blower housing and other cooling shrouds. Clean
the cooling fins and external surfaces as neces-
sary. Make sure the cooling shrouds are rein-
stalled.
NOTE: 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.
AIR FILTER
Your engine will not run properly using a dirty air
filter. Service air cleaner more often under dusty
conditions. See Engine Manual.
ENGINE OIL FILTER
Replace the engine oil filter every season or
every other oil change if the mower is used more
than 100 hours in one year.
SPARK PLUGS
Replace spark plugs at the beginning of each
mowing season or after every 100 hours of
operation, whichever occurs first. For spark plug
type and gap setting refer to your ENGINE
OWNER’S MANUAL.
IN-LINE FUEL FILTER (See Figs. 11 and 12)
The fuel filter should be replaced once each
season. If the fuel filter becomes clogged,
obstructing fuel flow to carburetor, replacement
is required.
• First turn off the fuel valve that is located
under the fuel tank of you mower.
• With the engine cool, remove the filter
and plug fuel line sections.
• Place new filter in position in fuel line with
arrow pointing toward the carburetor.
• Be sure there are no fuel leaks and
clamps are secure and properly
positioned.
• Immediately wipe up any spilled gasoline.

CLEANING
• Clean engine, battery, seat, finish, etc. of
all foreign matter.
• Keep finished surfaces and wheels free
of all gasoline, oil, etc.
• Protect painted surfaces with automotive
type wax
We do not recommend using a garden hose to
clean your mower unless the electrical system,
muffler, air filter and carburetor are covered to
keep water out. Water in the engine can shorten
the engine life.
