MUFFLER
Inspect and replace corroded muffler and spark arrester
(if equipped) as it could create a fire hazard and/or dam-
age.
SPARK PLUG(S)
Replace spark plug(s) 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
“PROD UCT SPEC I FI CA TIONS” section of this manual.
CLEANING
• Clean engine, battery, seat, finish, etc. of all foreign mat-
ter.
• Keep finished surfaces and wheels free of all gasoline,
oil, etc.
• Protect painted surfaces with au to mo tive type wax.
We do not recommend using a garden hose or pressure
washer to clean your riding mower unless the engine and
transmission are covered to keep water out. Water in engine
or transmission will shorten the useful life of your riding
mower. Use compressed air or a leaf blower to remove
grass, leaves and trash from riding mower and mower.
CLEAN AIR INTAKE/COOL ING AREAS
To ensure 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 ex-
tremely dusty, dirty conditions), remove the blower hous-
ing and other cooling shrouds. Clean the cooling fins and
external surfaces as necessary. Make sure the cooling
shrouds are re in stalled.
NOTE: Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or cooling
shrouds re moved will cause engine damage due to over-
heating.
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff to prevent
engine dam age from overheating. Clean with a wire brush
or compressed air to re move dirt and stub born dried gum
fibers.
AIR FILTER
Your engine will not run properly using a dirty air filter.
Replace the air filter every 100 hours of operation or every
season, whichever occurs first. Service air cleaner more
often under dusty conditions.
1. Remove cover knob and cover.
2. Carefully remove cartridge.
3. Clean base carefully to prevent debris from falling into

IMPORTANT: Petroleum solvents, such as kerosene, are
not to be used to clean the cartridge. They may cause
de te ri o ra tion of the cartridge. Do not oil cartridge. Do not
use pressurized air to clean cartridge.
