MAINTENANCE
• After oil has drained completely, close the drain valve
turning clockwise. Use the 7/16" (11mm) wrench to
apply a small amount ot torque to keep it closed. Do
not over tighten.
• Remove the drain tube and store in a safe place.
• Refill engine with oil through oil till dipstick tube. Pour
slowly. Do not overfill. For approximate capacity see
“PRODUCT SPECIFICATIONS” section of this man­
ual.
• Use gauge on oil fill cap/dipstick for checking level.
Be sure dipstick cap is tightened securely for accurate
reading. Keep oil at“FULL” line on dipstick.Tighten cap
onto the tube securely when finished.
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: Cperating the engine with a blocked grass screen,
dirty orplugged cooling fins, and/or cooling shrouds removed
will cause engine damage due to overheating.
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.
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 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 dam­
age.
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 (See Fig. 17)
The fuel filter should be replaced once each season. If fuel
filter becomes clogged, obstructing fuel flow to carburetor,
replacement is required,
• With engine cool, remove filter and plug fuel line sec­
tions.
• 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 automotive type wax.
We do not recommend using a garden hose or pressure
washer to clean your tractor unless the engine and trans­
mission 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.
