hours of operation, whichever occurs first.

TIONS” section of this manual.
IN-LINE FUEL FILTER
The fuel filter should 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.
• Be sure there are no fuel line leaks and
clamps 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 carbure­
tor are covered to keep water out. Water in
engine can result in a shortened engine
