NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
they will result in increased oil consumption
when used above 32°E Check your engine
oil level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 25 hours of
operation orat least once a year if the lawn
mower is not used for 25 hours in one
year.
Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.
TO CHANGE ENGINE OIL
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Be sure lawn mower is on level surface.
NOTE: Oil will drain more freely when
warm. Catch oil in a suitable container.

eration or every season, whichever occurs

CLEANING
IMPORTANT: For best performance, keep
mower housing free of built-grass and
trash. Clean the underside of your mower
after each use.
II,CAUTION: 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.
