MUFFLER
Do not operate tiller without muffler. Do not tamper with
exhaust system. Damaged 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 assembly, remove every 50 hours for cleaning and
Inspection. Replace if damaged.
SPARK PLUG
Replace spark plugs at the beginning of each tilling sea*
son or after every 50 hours of use, whichever comes first.

TRANSMISSION

unless serviced.
CLEANING
Do not clean your tiller when the engine and transmission
are hot. We do not recommend 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.
