CUSTOMER RESPONSIBILITIES
CLEANING
• Clean engine, battery, seat, finish, etc. of all foreign
matter.
• Keep finished surfaces and wheels free of all gasoline,
oil, etc.

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.
