MAINTENANCE
TO CHANGE ENGINE OIL (SEE FIGS. 15 AND 16)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
Be sure tractor is on level surface.
Oil will drain more freely when warm.
Catch oil in a suitable container.
Remove oil fill cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil.
Remove yellow cap from bottom fitting of drain valve
and install the drain tube onto the fitting.
OIL DRAIN VALVE
DRAIN
TUBE
FIG. 16
Unlock drain valve by pushing inward and turning
counterclockwise.
To open, pull out on the drain valve.
After oil has drained completely, close and lock the
drain valve by pushing inward and turning clockwise
until the pin is in the locked position as shown.
Remove the drain tube and replace the cap onto to the
bottom fitting of the drain valve.
Refill engine with oil through oil fill 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. For
accurate reading, insert dipstick into the tube and push
down firmly into place before removing. Keep oil up to,
but not over, the "FULL" line on dipstick. Push dipstick
down firmly into the tube when finished.
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 orplugged 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.
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 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. Iffuel
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 lifeof your tractor. Use
compressed air or a leaf blower to remove grass, leaves
and trash from tractor and mower.
