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
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 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.
IN-LINE FUEL FILTER (See Fig. 10)
The fuel filter should be replaced
once each
season.
If the fuel filter becomes
clogged,
obstructing
fuel flow to carburetor,
replacement
is required.
With the engine cool, remove the filter
and plug fuel line sections.
Place new filter in position
in fuel line with
arrow pointing
toward the carburetor.
Be sure there are no fuel leaks and
clamps
are secure and properly
positioned.

CLEANING
Clean engine,
battery, seat, finish, etc. of
all foreign
matter.
Keep finished

We do not recommend
using a garden
hose to
clean you mower unless the electrical
system,
muffler, air filter and carburetor
are covered
to
keep water out. Water in the engine can shorten
the engine life.
