TO SERVICE CARTRIDGE
• Replace a dirty, bent, or damaged car
tridge.
NOTE: Do not wash the paper cartridge
or use pressurized air, as this will damage
the cartridge.
• Reinstall the pre-cleaner (cleaned and
oiled) over the paper cartridge.
• Reassemble air cleaner, wing nut, cover
- and tighten knob securely.
CLEAN AIR INTAKE/COOLING AREAS
To insure proper cooling, make sure the
grass screen, cooling fins, and other
external surfaces of the engine are kept
clean at all times.
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 necessary. Make
sure the cooling shrouds are reinstalled.
NOTE: Operating the engine with a
blocked grass screen, dirty or plugged
cooling fins, and/or cooling shrouds re
moved will cause engine damage due to
overheating.
MUFFLER
Inspect and replace corroded muffler and
spark arrester (if equipped) as it could cre
ate 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”
on page 5 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 carbu
retor.
• Be sure there are no fuel line leaks and
clam.ps are properly positioned.

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 automo
tive type wax.
We do not recommend using a garden
hose to clean your tractor unless the elec
trical system, muffler, air filter and carbu
retor are covered to keep water out. Water
in engine can result in a shortened engine
life.
