|
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 25 hours of use, whichever comes first. Spark plug type and gap setting are shown in “PRODUCT SPECIFICATIONS” on page 3 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 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.
•Clean engine, wheels, finish, etc. of all foreign matter.
•Keep finished surfaces and wheels free of all gasoline, oil, etc.
•Protect painted surfaces with automotive type wax.
