CLEAN AIR SCREEN
Air screen must be kept free of dirt and
chaff to prevent engine damage from
overheating. Clean with a wire brush or
compressed air to remove dirt and
stubborn dried gum fibers.
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
removed will cause engine damage due
to overheating.
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.
• Loosen knob and remove cover.
TO SERVICE PRE-CLEANER
• Slide foam pre-cleaner off cartridge.
• Wash it in liquid detergent and water.
• Squeeze it dry in a clean cloth. Allow
it to dry.
• Saturate it in engine oil. Wrap it in
clean, absorbent cloth and squeeze to
remove excess oil.
TO SERVICE CARTRIDGE
• Replace a dirty, bent, or damaged
cartridge.
NOTE: Do not wash the paper cartridge
or use pressurized air, as this will
damage the cartridge.
• Remove nut and cartridge plate.
• Reinstall the pre-cleaner (cleaned and
oiled) over the paper cartridge.
• Check rubber seal for damage and
proper position around stud. Replace
if necessary.
• Reassemble air cleaner, cartridge
plate, and nut.
• Reinstall air cleaner cover and secure
by tightening knob.

ENGINE OIL FILTER
Replace the engine oil filter every
season or every other oil change if the
tractor is used more than 100 hours in
one year.
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.

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
electrical system, muffler, air filter and
carburetor are covered to keep water out.
Water in engine can result in a short-
22 ened engine life.
