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, kiip
mower housing free of built-grass and trash.
Clean the underside of your mower after
each use.
ACAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with the spark
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 shortened
engine life.
