CLEANING
IMPORTANT: For best performance,
keep mower housing free of built-up
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.
ACAUTION: Before performing any
service or adjustments:
1. Release control bar and stop engine.
2. Make sure the blade and all moving
parts have completely stopped,
3. Disconnect spark plug wire from spark
plug and place where it cannot come
in contact with plug.
