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.
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.

clean, absorbent cloth and squeeze to
remove excess oil.

CLEAN AfR 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 stub­
born dried gum fibers.
CLEAN AIR INTAKE/COOLING AREAS
To insure proper cooling, make sure the
grass screen, cooling fins, and other exter­
nal 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 cool­
ing shrouds. Clean the cooling fins and
externa! 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.
MUFFLER
Inspect and replace corroded muffler and
spark arrester (if equipped) as it could cre­
ate a fire hazard and/or damage.
SPARK PLUG(S)
Replace spark piug(s) at the beginning
of each mowing season or after every
100 hours of operation, whichever occurs
first. Spark plug type and gap setting are

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 auto­
motive type wax.
We do not recommend using a garden
hose or pressure washer to clean your
tractor unless the engine and transmis­
sion are covered to keep water out. Water
in engine or transmission will shorten the
useful life of your tractor. Use compressed
air or a leaf blower to remove grass,
leaves and trash from tractor and mower.
