TO CHANGE ENGINE OIL (See Figs. 10 ).
FIGURE 10
ENGINE OIL DRAIN
VALVE
PLASTIC TUBE
Be sure the mower is on a level surface.
Oil will drain more freely when warm.
Place a suitable container under the left
rear corner of the rear of the mower.
Remove oil dipstick. Be careful not to
allow dirt to enter the engine when
changing oil.
Using the clear plastic tube included with
your mower, place it over the end of the
drain valve located on the left side of
your engine.
Place the other end of the tube thru the
2" diameter hole on the left side of the
rear deck.
Be sure container is located under this
area of the mower.
Using a 10 mm wrench, turn the hex
head on the oil valve counter clockwise
until the oil is draining out of the tube.
After the oil has drained, turn the hex
head clockwise until it is tight (do not
over tighten).
Remove the plastic tube from the valve,
clean excess oil off of tube and store in a
safe place for the next use.
Refill engine with oil through the oil
dipstick tube. Pour slowly. Do not
overfill.
See Engine Owners Manual for type and
capacity of the oil.
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 neces-
sary. Make sure the cooling shrouds are rein-
stalled.
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.
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff to
prevent engine damage from overheating. Refer
to your engine manual for the proper cleaning
procedure.
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.
