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 automo-
tive type wax.
We do not recommend using a garden
hose to clean your tractor unless the elec-
trical system, muffler, air filter and carbure-
tor are covered to keep water out. Water
in engine can result in a shortened engine
