MAINTENANCE

TO CHANGE ENGINE OIL (See Fig. 23)

Determine temperature range expected before oil change. All oil must meet API service classification SG-SL.

Be sure tractor is on level surface.

Oil will drain more freely when warm.

Catch oil in a suitable container.

Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil.

Remove yellow cap from bottom fitting of drain valve and install the drain tube onto the fitting.

• Remove the drain tube and replace the cap onto to the

bottom fitting of the drain valve.

AIR FILTER

Your engine will not run properly using a dirty air filter. Clean the foam pre-cleaner after every 25 hours of operation or every season. Service paper cartridge every 50 hours of operation or every season, whichever occurs first. See engine manual.

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.

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. See engine manual.

IN-LINE FUEL FILTER (See Fig. 24)

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.

• Refill engine with oil through oil fill dipstick tube. Pour

slowly. Do not overfill. For approximate capacity see

“PRODUCT SPECIFICATIONS” section of this man-

ual.

• Use gauge on oil fill cap/dipstick for checking level.

Insert dipstick into the tube and rest the oil fill cap on

the tube. Do not thread the cap onto the tube when

taking reading. Keep oil at “FULL” line on dipstick.

Tighten cap onto the tube securely when finished.

CLEAN AIR SCREEN

Air screen must be kept free of dirt and chaff to prevent engine damage from overheating. Clean with a wire brush or compressed air to remove dirt and stubborn dried gum fibers. See engine manual.

FIG. 24

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.
