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
or pressure washer to clean your riding
mower unless the engine and transmission
are covered to keep water out. Water in en-
gine or transmission will shorten the useful
life of your riding mower. Use compressed
air or a leaf blower to remove grass, leaves
and trash from riding mower and mower.
