COOLING SYSTEM
Your engine is air cooled. For proper en-
gine performance and long life keep your
engine clean.
• Clean air screen frequently using a
stiff-bristled brush.
• Remove blower housing and clean as
necessary.
• Keep cylinder fins free of dirt and chaff.

MUFFLER
Do not operate tiller without muffler. Do
not tamper with exhaust system. Dam-
aged mufflers or spark arresters could
create a fire hazard. Inspect periodically
and replace if necessary. If your engine is
equipped with a spark arrester screen as-
sembly, remove every 50 hours for clean-
ing and inspection. Replace if damaged.
SPARK PLUG
Replace spark plugs at the beginning of
each tilling season or after every 25 hours
of use, whichever comes first. Spark plug
type and gap setting are shown in "PROD-
UCT SPECIFICATIONS" on page 4 of this
manual.
TRANSMISSION
Your transmission is sealed and will not
require lubrication unless serviced.
CLEANING
Do not clean your tiller when the engine
and transmission are hot. We do not rec-
ommend using pressurized water (garden
hose, etc.) to clean your unit unless the
gasket area around the transmission and
the engine muffler, air filter and carburetor
are covered to keep water out. Water in
engine will shorten the useful life of your
tiller.
• Clean engine, wheels, finish, etc. of all
foreign matter.
• Keep finished surfaces and wheels free
of all gasoline, oil, etc.
• Protect painted surfaces with auto-
motive type wax.
