CUSTOMER RESPONSIBILITIES
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
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.
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 mower is used more
than 100 hours in one year.
SPARK PLUGS
Replace spark plugs at the beginning of each
mowing season or after every 100 hours of
operation, whichever occurs first. For spark plug
type and gap setting refer to your ENGINE
OWNER’S MANUAL.

under the fuel tank of you mower.
With the engine cool, remove the filter

PLASTIC TUBE
To insure proper cooling, make sure the grass
screen, cooling fins, and other external surfaces
of the engine are kept clean at all times.
Place the other end of the tube thru the
2" diameter hole on the left side of the

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.
