AIR FILTER

Your engine will not run properly and may be damaged by using a dirty air filter. Replace the air filter cartridge every 100

hours of operation or every season, which- ever occurs first. Service air cleaner more

often under dusty conditions.

TO CLEAN AIR FILTER

1.Loosen screw and tilt cover to remove.

2.Carefully remove cartridge.

3.Clean by gently tapping on a flat sur-

ace. If very dirty, replace cartridge.

CAUTION: Petroleum solvents, such as kerosene, are not to be used to clean car-

tridge. They may cause deterioration of the cartridge. Do not oil cartridge. Do not use pressurized air to clean or dry cartridge.

MUFFLER

Inspect and replace corroded muffler as it could create a fire hazard and/or damage.

SPARK PLUG

Replace spark plug 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 the "PRODUCT SPECIFIC- ATIONS" section of this manual.

CLEANING

IMPORTANT: For best performance, keep mower housing free of built-grass and trash. Clean the underside of your mower after each use.

_CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

Clean the underside of your lawn mower by scraping to remove build-up of grass and trash.

Clean engine often to keep trash from

accumulating. A clogged engine runs hotter and shortens engine life.

Keep finished surfaces and wheels free of all gasoline, oil, etc.

We do not recommend using a garden hose to clean lawn mower unless the

electrical system, muffler, air filter and carburetor are covered to keep water out. Water in engine can result in short- ened engine life.
