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 or pressure washer to clean your tractor unless the engine and transmis- sion are covered to keep water out. Water in engine or transmission will shorten the useful life of your tractor. Use compressed

air or a leaf blower to remove grass, leaves and trash from tractor and mower.
