Purchase fuel in quantities that can he

usedwithin 30 days to assure fuel freshness.

AWARNING: Expedenoe indicates that

alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an

engine while in storage. To avoid engine problems, the fuel system should be

emptied before storage of 30 days or longer. Drain the gas tank, start the

engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel

next season• See Storage Instructions for additional information. Never use engine

or carburetor cleaner products in the fuel

tank or permanent damage may eccur.

A.CAUTION: Fillto bottom of gas tank filler neck. Do not overfill. Wipe off any

spilledoil or fuel. Do not store, spill or use

gasoline near an open flame.

NOTE: Due to protective coatings on the

engine, a small amount of smoke may be present dudng the initial use of the

product and should be considered normal.

MOWINGTIPS

• Under certain conditions,such as very

tall grass, it may be necessary to raise the height of Cutto reduce pushing

effort and to keep from overloadingthe

engine and leaving clumps of grass clippings. It may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time.

• For extremely heavy cutting,reduce the width of cut by ovedapping previously cut path and mow slowly.

• For better grass bagging and most cuttingconditions, the engine speed should be set in the fast position.

• When using a rear discharge lawn mower in moist, heavy grass, clumps of

cut grass may not enter the grass

catcher. Reduce ground speed

(pushing speed) and/or run the lawn

mower over the area a second time.

• If a trail of clippingsis left on the right side of a rear discharge mower, mow in a clockwise directionwith e small ovedap to collectthe clippingson the next pass.

• Pores in cloth grass catchers can

become filled with dirt and dust with use and catchers will collect less grass. To prevent this, regularly hose catcher off

with water and let dry before using.

• Keep top of engine around starter clear and clean of grass clippings and chaff.

This will help engine air flow and

extend engine life,

MULCHING MOWING TIPS

IMPORTANT: For best performance, keep mower housing free of built-up grass and

trash. Clean UNDERSIDE OF MOWER

HOUSING after each use. See "Cleaning" in MAINTENANCE section of this manual.

TO SHARPEN BLADE

NOTE: We do not recommend sharpening blade - but if you do, be sure

the blade is balanced.

Care should be taken to keep the blade balanced. An unbalanced blade will cause eventual damage to lawn mower or engine.

• The blade can be sharpened with a file

or on a grindingwheel. Do not attempt to sharpen while on the mower.

• To check blade balance, drive a nail into a beam or wall. Leave about one inch of the straight nail exposed. Place

center hole of blade over the head of

the nail. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced.

with API service classificationSF, SH or

SG, Select the oil's SAE viscositygrade according to your expected operating temperature.

NOTE: Although multi--viscosity oils

(5W30, 10W30 etc.) improve startingin

cold weather, these multi--viscosity oils will result in increased oil consumption

when used above 32"F. Check your

engine oil level more frequently to avoid

possible engine damage from running low on oil

Change the oilafter every 25 hours of

operation or at least once a year if the

lawn mower is not used for 25 hours in one year.

Check the crankcase oil level before

startingthe engine and after each five (5) hours of continuous use. "lightenoil plug securely each time you check the oil level.

TO CHANGE ENGINE OIL

NOTE: Beforatipping lawn mower to

drain oil, drain fuel tank by running

engine until fuel tank is empty.

• Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.

• Remove engine oil cap; lay aside on a clean surface.

• Tip lawn mower on itsside and drain oil

into a suitable container. Rock lawn

mower back and forth to remove any oil trapped inside of engine.

• Wipe off any spilled oil on lawn mower

and on side o! engine.

• Fill engine with oil. Fill only to the

"FULL" line on the dipstick. DO NOT

OVER FILL.

FUEL SYSTEM

IMPORTANT: It is importantto prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel filter,fuel hose, or tank during storage,

Also, experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.

• Drain the fuel tank.

• Start the engine and let it run until the

fuel lines and carburetor are empty.

• Never use engine or carburetor cleaner products in the fuel tank or permanent

damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable

alternative in minimizing the formation of fuel gum deposits during storage, Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach

the carburetor. Do not drain the gas tank and carburetor if usingfuel stabilizer.

ENGINEOIL

Drain oil (with engine warm) and replace with clean engine oil. (See "ENGINE" in the Maintenance section of this manual).

CYLINDER

• Remove spark plug.

• Pour one ounce (29 ml) of oil through spark plug hole into cylinder.

• Pull starter handle slowly a few times to distribute oil,

• • Replace with new spark plug.

OTHER

• Do not store gasolinefrom one season to another.

• Replace your gasolinecan if your can

starts to rust. Rust and/or dirt in your

gasoline will cause problems.

• If possible, store your unit indoors and

cover it to give protection from dust and dirt.

• Cover your unit with a suitable protec- tive cover that does not retain moisture.

Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your unit to rust.

IMPORTANT: Never cover mower while

engine and exhaust areas are still warm.

A, CAUTION: Never store the lawn mower with gasoline in the tank inside a building

where fumes may reach an open flame or spark. Allowthe engine to cool before storing in any enclosure.
