CLEANING
•Clean engine, battery, seat, 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.
We do not recommend using a garden hose to clean your tractor unless the electrical system, muffler, air filter and carburetor are covered to keep water out. Water in engine can result in a shortened engine life.
