------Gasoline filler cap

MOWING TIPS

GAS

• Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane, Do not mix oil with gasoline.

Purchase fuel in quantities that can be

used within 30 days to assure fuel freshness.

•

WARNING: Experience indicates that alcohol • blended fuels (called gasohol or using ethanol

or methanol) can attract moisture which leads to separation and formationof 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 fuel tank, start the engine and let it

run until 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 fuel tank or permanent damage may occur.

TO START ENGINE

• To start a cold engine, push primer five

(5) times before trying to start. Use a firm push. This step is not usually necessary when starting an engine

which has already run for a few minutes.

• Hold operator presence control bar down to the handle and pull starter

handle quickly.

Do not allow starter rope to snap back.

• To stop engine, release operator presence control bar.

Under certain conditions, such as very

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

and to keep from overloading the 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 overlapping previously cut path and mow slowly.

For better grass bagging and most cutting conditions, the engine speed

should be set in the fast position.

For side discharge lawn mowers, cutting in a counter-clockwise direction, starting at the outside of the area to be cut, spreads grass clippings more evenly and puts less load on the engine.

To keep clippings off of walkways, flower beds, etc., make the first cuts in a clockwise direction.

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 peffo_, keep mower housingfree of built-upgrass and trash. See "Cleaning"in MAINTENANCE sectionof this manual.

• The special mulching blade will recurthe

grass clippingsmany times and reduce

them in size so that as they fall onto the not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients for the lawn. Always mulch with your highest

engine (blade) speed as INs will provide the best recurringaction of the blades.

• Avoid cuttingyour lawn when itis wet. Wet grass tends to form dumps and interferes

with the mulching action. The best time to

mow your lawn is the early afternoon. At this time the grass has dried and the newly

cut area will not be exposed to the direct sun.

• For best results, adjust the lawn mower

cutting height so that the lawn mower cuts

off only the top one-third of the grass blades

If the lawn is overgrown it will be necessary to raise the height of cut to reduce pushing

effort and to keep from overloading the engine and leaving clumps of mulched grass. For extremely heavy mulching, reduce your width of cut by overlapping previously cut path and mow slowly.

• Certain types of grass and grass cond'_ons may require that an area be mulched a

second time to qompletely hide the dippings. When-doing a second cut, mow across or perpendicular to the first ct_tpath.

• Change your cutting pattern from Week to week. Mow north to south one week then

change to east to west the next week. This will help prevent matting and graining ofthe lawn.

ENGINE

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

productsin the fuel tank or permanent damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable

altemative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container.

Always follow the mix ratiofound 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.

ENGINE OIL

Drain oil (with engine warm) and replace with dean engine oil. (See "ENGINE" in the

Maintenance section of this manual).

CYMNDER

• Remove spark plug.

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

• Pull starter handle slowly a few times to distributeoil.

• Replace with new spark plug,

OTHER

• Do not store gasoline from one season to another.

• Replacayour gasoline can ifyourcan starts

to rust. Rust and/or dirt in your gasoline will cause problems.

• ff possible, store yoTJrunit indoors and cover

it to give protection from dust and dirt.

• Cover your unitwith a suitable protectiv_

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.

ACAUTION: Never store the lawn mower with gasoline in the tank inside a

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