ENGINE COOLING FINS
Remove any dust, dirt or oil from engine
cooling fins to prevent engine damage
from overheating. See engine manual.
AIR FILTER
Your engine will not run properly using a
dirty air filter. Clean the foam pre-cleaner
after every 25 hours of operation or
every season. Service paper cartridge
every 100 hours of operation or every
season, whichever occurs first.
Service air cleaner more often under
dusty conditions. See engine manual.
MUFFLER
Inspect and replace corroded muffler
and spark arrester (if equipped) as it
could create a fire hazard and/or
damage.
SPARK PLUGS
Replace spark plugs at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs
first. Spark plug type and gap setting are
shown in "PRODUCT SPECIFICATIONS"
section of this manual.
IN-LINE FUEL FILTER
The fuel filter should be replaced once
each season. If fuel filter becomes
clogged, obstructing fuel flow to carbure-
tor, replacement is required.
• With engine cool, remove filter and
plug fuel line sections.
• Place new fuel filter in position in fuel
line with arrow pointing towards
carburetor.
• Be sure there are no fuel line leaks
and clamps are properly positioned.
• Immediately wipe up any spilled
gasoline.
