SPARK PLUG
Replace spark plug at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs
first. Spark plug type and gap setting are
shown in "PRODUCT SPECIFICATIONS"
in the Maintenance section of this manual.
CLEANING
IMPORTANT: For best performance, keep
mower housing free of built-grass and
trash. Clean the underside of your mower
after each use.
ICI, C AUTION: 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 short-
ened engine life.
_WARNING: To avoid serious injury, before
performing any service and 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 wire where it cannot
come in contact with the spark plug.
