pacity is 18.5 oz. If oil is not completely
drained from engine, you may not need
the entire container of a 20 oz. bottle of
oil. Slowly pour 3/4 of the oil from the
container down the oil fill spout into the
engine.

DO NOT thread the cap into the tube
when taking reading.

oil and rechecking the dipstick until it

before starting engine.

plug.
AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air filter.
Replace the air filter every 100 hours of
operation or every season, whichever oc-
curs first. Service air cleaner more often
under dusty conditions.
Tabs
MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or damage.
SPARK PLUG

each mowing season or after every 100
hours of operation, whichever occurs
first. Spark plug type and gap setting
are shown in the "PRODUCT SPECIFIC-
ATIONS" 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.
[LCAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with 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.
