ENGINE OIL FILTER

Replace the engine oil ﬁlter every season or every other oil change if the tractor is used more than 100 hours in one year.

MUFFLER

Inspect and replace corroded mufﬂer and spark arrester (if equipped) as it could create a ﬁre hazard and/or dam- age.

SPARK PLUGS

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” section of this manual.

IN-LINE FUEL FILTER (See Fig. 15)

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 sec- tions.

•Place new fuel ﬁlter in position in fuel line with arrow pointing towards carburetor.

•Be sure there are no fuel line leaks and clamps are properly positioned.

•Immediately wipe up any spilled gasoline.

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 tractor unless the engine and trans- mission are covered to keep water out. Water in engine or transmission will shorten the useful life of your tractor. Use compressed air or a leaf blower to remove grass, leaves and trash from tractor and mower.
