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 automotive 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.
