SPARK PLUG
Change your spark plug each year to
make your engine start easier and run
better. Set spark plug gap at .030 inch.
CLEANING
IMPORTANT: For best performance,
keep mower housing free of built-up
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 the spark
plug.
• Turn lawn mower on its side. Make
sure air filter and carburetor are up.
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
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.
