MUFFLER

Inspect and replace corroded muffler as it could create a fi re 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

rst. 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 fi nished 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, muffl er, air fi lter and carburetor are covered to keep water out. Water in engine can result in short- ened engine life.
