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 mat- ter.

•Keep finished surfaces and wheels free of all gasoline, oil, etc.

•Protect painted surfaces with automotive type wax.
