CUSTOMER RESPONSIBILITIES

CLEAN AIR INTAKE/COOLING AREAS

To insure proper cooling, make sure the grass screen,

cooling fins, and other external surfaces of the engine are
kept dean at all times.

Every 100 hours of operation (more often under extremely

dusty, dirty conditions), remove the blower housing and
other cooling shrouds. Clean the cooling fins and external
surfaces as necessary. Make sure the cooling shrouds are

reinstalled.

NOTE: Operating the engine with a blocked grass screen,
dirty or plugged cooling fins, and/or cooling shrouds re­
moved will cause engine damage due to overheating.

ENGINE OIL FILTER (See Fig. 16)

Replace the engine oil filter every season or every other oil

change if the tractor is used more than 100 hours in one
year.

Drain oil from engine crankcase (See ‘TO CHANGE

ENGINE OIL” in this section of this manual, through

step remove drain plug).

® Remove oil filter and wipe off filter adapter,

= Apply a thin coating of new engine oil to the rubber

gasket on replacement oil filter.

Install replacement oil filter on filter adapter. Turn oil

filter clockwise until rubber gasket contacts the filter
adapter, then tighten filter an additional 1/2 turn.

Fill crankcase with new oil (See “TO CHANGE EN­

GINE OIL” in this section of this manual). For approxi­

mate capacity see “PRODUCT SPECIFICATIONS” on

page 3 of this manual.

Start the engine and check for oil leaks. Correct any

leaks before placing engine into full operation.

MUFFLER

Inspect and replace corroded muffler and spark arrester (if

equipped) as it could create a fire ha2ard and/or damage.

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” on page 3 of this manual.

IN-LINE FUEL FILTER (See Fig. 17)

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.

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 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.
