Replace spark plugs at the beginning of each mowing
season or after every 100 hours of operation, whichever
occurs first. Spark plug type and gap setting are shown in
"PRODUCT SPECIFICATIONS" on page 3 of this manual.
IN-LINE FUEL FILTER (See Fig. 20)
The fuel filter should be replaced once each season. If fuel
filter becomes clogged, obstructing fuel flow to carburetor,
replacement is required.
• With engine cool, remove filter and plug fuel line
sections.

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 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.
