IN-LINE FUEL FILTER
The fuel filtershould be replaced once
each season. If fuel filter becomes
clogged, obstructing fuel flow to carbure-
tor, replacement is required.
• With engine cool, remove filter and plug
fuel line sections.
• Place new fuel filter in position in fuel
line with arrow pointing towards carbu-
retor.

clam.ps are properly positioned.

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 carbu-
retor are covered to keep water out. Water
in engine can result in a shortened engine
life.
