SPARK PLUG

make your engine start easier and run

CLEANING
IMPORTANT: For best performance, keep
mower housing free of built--up grass
and trash. Clean underside of mower
housing after each use.
AI_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.
_LCAUTION: Before performing any
service or adjustments:
• Release control bar and stop engine.
• Make sure the blade and all moving
parts have completely stopped.
• Disconnect spark plug wire from spark
plug and place where it cannot come in
contact with plug.
