SPARK PLUGS

IN-LINE FUEL FILTER (See Fig. 13)

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.

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

•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.
