MAINTENANCE

Grass Catcher

•The grass catcher may be hosed with water, but must be dry when used.

•Check your grass catcher often for damage or deterioration. Through normal use it will wear. If catcher needs replacing, replace only with approved replacement catcher shown in the Repair Parts section of this manual. Give the mower model number when ordering.

Muffler

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

Cleaning

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT- UP GRASS AND TRASH. CLEAN THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.

•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/wheels free of 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 shortened engine life.

Clean Under Drive Cover

Clean under drive cover at least twice a season. Scrape underside of cover with putty knife or similar tool to remove any build-up of trash or grass on underside of drive cover.

WARNING!

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