HOW TO USE YOUR LAWN MOWER

ENGmNE SPEED

The engine speed was set at the factory for optimum performance.

Speed is not adjustable.

ENGmNE ZONE CONTROL

II. AUTmON: Federal regulations require an engine control to be installed on this lawn mower in order to minimize the

DRmVE CONTROL

Self-propelling is controlled by hold ing the operator presence control bar down to the handle and pulling the drive control bar up to the handle.

The closer to the handle the bar is pulled. the faster the unit will travel.

Forward motion will stop when either the operator presence control bar or drive control bar are released.

To stop forward motion without stopping engine. release the drive control bar only. Hold operator presence control bar down against handle to continue mowing without self-propelling.

NOTE: If after releasing the drive control the mower will not roll backwards. push the mower forward slightly to disengage drive wheels.

To keep drive control engaged when turning corners. push down on the handle to lift the front wheels off the

DRIVE CONTROL ADJUSTMENT

Over time. the drive control system may become "loose". resulting in decreased speed.

There is a thumbscrew on the underside of the drive control housing to increase tension on the drive cable.

Pro ceed as follows:

Turn unit off and disconnect spark plug wire from spark plug.

Rotate thumbscrew counter-clockwise to tighten the drive cable.

Operate mower to test drive speed.

If condition fails to improve after the above steps (forward speed remains the same). your drive belt is worn and should be replaced.

NOTE: If mower begins to "creep" forward. the drive cable is too tight.

Rotate thumb screw clockwise to loosen drive cable.

BEFORE STARTmNG ENGINE

ADD OIL

Your lawnmower is shipped without oil in the engine.

For type and grade of oil to use. see "ENGINE" in the Maintenance section of this manual.

CAUTION: DO NOT overfill engine with oil. or it will smoke heavily from the muffler on startup.

Be sure lawnmower is level.

Remove oil dipstick from oil fill spout.

You receive a container of oil with the

ATTACH FUEL CAP CARTRmDGE

Your mower is equipped 'with a special FRESH START TMfuel cap and continuous fuel preserver cartridge.

See the infor mation and instructions packed with the FRESH STARTTM cartridge.

Snap cartridge into bottom of fuel cap.

NOTE: Do not remove the silver foil seal on the side of cartridge that snaps into fuel cap.

Grasp the white peel tab and pull to remove the entire seal.

Screw fuel cap onto fuel tank after fill ing tank with gasoline.

Replace cartridge when empty (about once a season).

Check preserver level visually.

1DANGER: Cartridge fluid is HARMFUL OR FATAL IF SWALLOWED.

Avoid contact

ADD GASOUNE

Fill fuel tank to bottom of tank filler neck.

Do not overfill.

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 fresh ness. CAUTmON: Wipe off any spilled oil or fuel.

Do not store. spill or use gasoline near an open flame.

CAUTmON: Alcohol blended fuels

(called gasohol or using ethanol or metha nol) 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.

Empty 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 occur.

TO STOP ENGINE

To stop engine. release operator pres ence control bar.

TO START ENGINE

NOTE: Due to protective coatings on the engine. a small amount of smoke may be present during the initial use of the prod uct and should be considered normal.

To start a cold engine. push primer three (3) 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 turn the start

MULCHmNG MOWmNG TIPS

The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and 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 this will provide the best recut ting action of the blades. Avoid cutting your lawn when it is wet.

Wet grass tends to form clumps and interferes with the mulching action.

The best time to mow your lawn is the early afternoon.

At this time the grass has dried. yet the newly cut area will not be exposed to direct sunlight. 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 grass. reduce your width of cut by overlapping previously cut path and mow slowly.

MOWmNG TIPS

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 clip pings.

It may also be necessary to re duce 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 cut ting conditions. the engine speed should be set in the FAST position. Pores in cloth grass catchers can be come filled with dirt and dust with use

MAX 1/3

Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings.

When doing a sec ond cut. mow across (perpendicular) to the first cut path. Change your cutting pattern from week to week.

Mow north to south one week

SPARK PLUG

Replace spark plug at the beginning of each mowing season or after every hours of operation. whichever occurs first.

If your engine does not operate properly due to sus pected carburetor problems. take your lawn mower to a Sears or other qualified service center for repair and/or adjustment. iMPORTANT: Never tamper with the engine governor. which is factory set for proper engine speed.

Overspeeding the engine above the factory high speed setting can be dangerous.

If you think the engine-governed high speed needs adjusting. contact a Sears or other qualified service center. which has proper equipment and experience to make any necessary adjustments.

FUEL SYSTE

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

Also. alcohol blended fuels (called gasoho[ 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.

Empty the fuel tank by starting the en gine and letting 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 stor age container.

Always follow the mix ratio found on stabilizer container.
