SAFETY RULES

Safe Operation Practices for Walk-Behind Mowers

IMPORTANT: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROW ING OBJECTS. FAILURE

TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.

I. GENERAL OPERATION

• Read, understand, and follow all instructions on the machine and in the manual(s) before starting. Be thor-

ough ly familiar with the controls and the proper use of the machine before starting.

• Do not put hands or feet near or under rotating parts.

Keep clear of the discharge opening at all times.

• Only allow responsible individuals, who are familiar with the instructions, to operate the machine.

• Clear the area of objects such as rocks, toys, wire, bones, sticks, etc., which could be picked up and thrown by the blade.

• Be sure the area is clear of other people before mow-

ing. Stop machine if anyone enters the area.

• Do not operate the mower when barefoot or wearing open sandals. Always wear substantial foot wear.

• Do not pull mower backwards unless absolutely nec-

es sary. Always look down and behind before and while moving backwards.

• Do not operate the mower without proper guards, plates, grass catcher or other safety protective devices in place.

• See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by the manufacturer.

• Stop the blade(s) when crossing gravel drives, walks, or roads.

• Stop the engine (motor) whenever you leave the equip-

ment, before cleaning the mower or unclogging the chute.

• Shut the engine (motor) off and wait until the blade comes to complete stop before removing grass catch er.

• Mow only in daylight or good artifi cial light.

• Do not operate the machine while under the infl uence of alcohol or drugs.

• Never operate machine in wet grass. Always be sure of your footing: keep a fi rm hold on the handle and walk; never run.

• Disengage the self-propelled mechanism or drive clutch on mowers so equipped before starting the engine (motor).

• If the equipment should start to vibrate abnormally, stop the engine (motor) and check immediately for the cause. Vibration is generally a warning of trouble.

• Always wear safety goggles or safety glasses with side shields when operating mower.

II. SLOPE OPERATION

Slopes are a major factor related to slip and fall accidents which can result in severe injury. All slopes require extra caution. If you feel uneasy on a slope, do not mow it.

DO:

• Mow across the face of slopes: never up and down. Exercise extreme caution when changing direction on slopes.

• Remove obstacles such as rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Tall grass can hide obstacles.

2

DO NOT:

• Do not trim near drop-offs, ditches or embankments.

The operator could lose footing or balance.

• Do not trim excessively steep slopes.

• Do not mow on wet grass. Reduced footing could cause slipping.

III. CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

• Keep children out of the trimming area and under the watchful care of another re spon si ble adult.

• Be alert and turn machine off if children enter the area.

• Before and while walking backwards, look behind and down for small children.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

IV. SERVICE

• Use extra care in handling gasoline and other fuels.

They are fl ammable and vapors are explosive.

- Use only an approved container.

- Never remove gas cap or add fuel with the

engine running. Allow engine to cool before

refueling. Do not smoke.

- Never refuel the machine indoors.

- Never store the machine or fuel container inside

where there is an open fl ame, such as a water heater.

• Never run a machine inside a closed area.

• Never make adjustments or repairs with the engine

(motor) running. Disconnect the spark plug wire, and keep the wire away from the plug to prevent accidental starting.

• Keep nuts and bolts, especially blade attachement bolts, tight and keep equipment in good condition.

• Never tamper with safety devices. Check their proper operation regularly.

• Keep machine free of grass, leaves, or other debris build-up. Clean oil or fuel spillage. Allow machine to cool before storing.

• Stop and inspect the equipment if you strike an object.

Repair, if necessary, before restarting.

• Never attempt to make wheel height adjustments while the engine (motor) is running.

• Grass catcher components are subject to wear, dam-

age, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check com po nents and replace with manufacturer’s rec om mend ed parts, when necessary.

• Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.

• Do not change the engine governor setting or overspeed the engine.

Look for this symbol to point out im-

por tant safety precautions. It means

SAFE TY IS IN VOLVED.

CAUTION: Always disconnect spark plug wire and place wire where it cannot contact spark plug in order to prevent ac ci den tal adjusting or making re pairs.

WARNING: Engine exhaust, some of cals known to the State of Cal i for nia to cause can cer and birth defects or oth er re pro duc tive harm.

WARNING: Battery posts, terminals and related ac ces so ries contain lead and lead compounds, chemicals known to the State of Cal i for nia to cause can cer and birth defects or oth er re pro duc tive harm. Wash hands after handling.

CAUTION: Muffl er and other engine parts become extremely hot during operation and remain hot after engine has stopped. To avoid severe burns on contact, stay away from these areas.

OPERATION

BEFORE STARTING ENGINE

ADD OIL (See Figs. 14 and 15)

Your lawnmower is shipped without oil in the engine. For type and grade of oil to use, see “EN GINE” in the Maintenance section of this manual.

CAUTION: DO NOT overfi ll engine with oil, or it will smoke heavily from the muffl er on startup.

1. Be sure lawnmower is level.

2. Remove oil dipstick from oil fi ll spout.

3. Engine holds 18.5 ounces of oil. For type and grade of oil to use, see “ENGINE” in the Maintenance section of this manual.

4. Pour oil slowly. Do not overfi ll. Wait one minute to allow oil to settle. Use guage on oil fi ll cap/dipstick for checking level. Insert dipstick into the tube and rest the oil fi ll cap on the tube. DO NOT thread the cap into the tube when taking reading.

5. Always be sure to tighten dipstick before starting engine.

IMPORTANT:

• Check oil level before each use. Add oil if needed. Fill to full line on dipstick.

• Change the oil after every 25 hours of operation or each season. You may need to change the oil more often under dusty, dirty conditions. See “TO CHANGE EN-

GINE OIL” in the Maintenance section of this manual.

ADD GASOLINE (See Fig. 15)

• Fill fuel tank to bottom of tank fi ller neck. Do not overfi ll. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oil with gasoline.

Purchase fuel in quan ti ties that can be used within 30 days to assure fuel freshness.

CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open fl ame.

Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and for ma tion 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 stor age 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

In struc tions for additional information.

Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

MULCHING MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER

HOUSING FREE OF BUILT-UP GRASS AND TRASH. SEE

“CLEANING” IN THE MAINTENANCE SECTION OF THIS

MANUAL.

• 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 recutting 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 (See Fig. 17). 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.

MOWING 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 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.

• Pores in cloth grass catchers can become fi lled 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 fl ow and extend engine life.

MAX 1/3

FIG. 17

• 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 second cut, mow across (perpendicular) to the fi rst cut path.

• 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 of the lawn.

Always observe safety rules when performing any main-

te nance.

TIRES

• Keep tires free of gasoline, oil, or insect control chem-

i cals which can harm rubber.

• Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.

DRIVE WHEELS

Check rear drive wheels each time be fore you mow to be sure they move freely.

The wheels not turning freely means trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free drive wheels.

If necessary to clean the drive wheels, be sure to clean both rear wheels.

BLADE CARE

For best results, mower blade must be kept sharp. Re place bent or dam aged blades.

TO REMOVE BLADE (See Fig. 18)

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

2. Turn lawn mower on its side. Make sure air fi lter and carburetor are up.

3. Use a wood block between blade and mower hous ing to prevent blade from turning when re mov ing blade bolts.

NOTE: Protect your hands with gloves and/or wrap blade with heavy cloth.

4. Remove blade bolts by turning counter-clockwise.

TO REPLACE BLADE (See Fig. 18)

1. Position the blade and spacer. Be sure the trailing edge of blade (opposite sharp edge) is up toward the engine and install the blade bolts.

2. Use block of wood between blade and lawn mower housing and tighten the blade bolts, turning clockwise.

• The recommended tightening torque is 36-44 ft. lbs.

IMPORTANT: BLADE BOLTS ARE HEAT TREATED. IF BOLTS

NEED REPLACING, REPLACE ONLY WITH APPROVED BOLTS

SHOWN IN REPAIR PARTS SECTION OF THIS MANUAL.

TRAILING EDGE

MAINTENANCE

TO SHARPEN BLADE

NOTE: We do not recommend sharp en ing blade - but if you do, be sure the blade is balanced.

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

• The blade can be sharp ened with a fi le or on a grinding wheel. 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 ex posed.

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.

GRASS CATCHER

• The grass catcher may be hosed with water, but must be dry when used.

• Check your grass catcher often for damage or de te ri o ra tion. Through normal use it will wear. If catcher needs replacing, replace only with ap proved replacement catcher shown in the Repair Parts section of this manual. Give the lawn mower model number when ordering.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service classifi cation SF-SJ. Select the oil's SAE viscosity grade according to your expected operating temperature.

NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, and you should check your engine oil level frequently to avoid possible engine damage from running low on oil.

Change the oil after 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 starting the engine and after each fi ve (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.

CLEANING

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER

HOUSING FREE OF BUILT-UP GRASS AND TRASH. CLEAN

THE UNDERSIDE OF YOUR MOWER AFTER EACH USE.

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

• Clean the underside of your lawn mower by scraping to remove build-up of grass and trash.

• Clean engine often to keep trash from accumulating. A clogged engine runs hotter and shortens engine life.

• Keep fi nished surfaces and wheels free of all gasoline, oil, etc.

• We do not recommend using a garden hose to clean lawn mower unless the electrical system, muffl er, air fi lter and carburetor are covered to keep water out.

Water in engine can result in shortened engine life.

CLEAN UNDER DRIVE COVER

Clean under drive cover at least twice a season. Scrape underside of cover with putty knife or similar tool to remove any build-up of trash or grass on underside of drive cover.

SERVICE AND ADJUSTMENTS

CAUTION: TO AVOID SERIOUS INJURY, BEFORE PERFORMING ANY SERVICE OR ADJUSTMENTS:

1. Release control bar and stop engine.

2. Make sure the blade and all moving parts have completely stopped.

3. Disconnect the spark plug wire from the spark plug and place the wire where it cannot come into contact with the spark plug.

ENGINE

Maintenance, re pair, or re place ment of the emission con-

trol de vic es and sys tems, which are be ing done at the cus tom ers expense, may be performed by any non-road engine repair es tab lish ment or individual. Warranty repairs must be performed by an authorized engine man u fac tur er's service outlet.

ENGINE SPEED

Your engine speed has been factory set. Do not attempt to increase engine speed or it may result in personal injury. If you believe that the engine is running too fast or too slow, take your lawn mower to an authorized service center for repair and adjustment.

CARBURETOR

Your carburetor is not adjustable. If your engine does not operate properly due to suspected carburetor problems, take your lawn mower to an authorized service center for repair and/or adjustment.

IMPORTANT: NEVER TAMPER WITH THE ENGINE GOVERNOR,

WHICH IS FACTORY SET FOR PROPER ENGINE SPEED.

OVER SPEED ING THE ENGINE ABOVE THE FACTORY HIGH

SPEED SETTING CAN BE DANGEROUS. IF YOU THINK THE

ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING,

CONTACT YOUR NEAREST AUTHORIZED SER VICE CEN TER,

WHICH HAS PROPER EQUIP MENT AND EXPERIENCE TO

MAKE ANY NEC ES SARY ADJUSTMENTS.

STORAGE

Immediately prepare your lawn mower for storage at the end of the season or if the unit will not be used for 30 days or more.

LAWN MOWER

When lawn mower is to be stored for a period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dry area.

16

1. Clean entire lawn mower (See “CLEANING” in the

Maintenance section of this manual).

2. Lubricate as shown in the Maintenance section of this manual.

3. Be sure that all nuts, bolts, screws, and pins are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary.

4. Touch up all rusted or chipped paint surfaces; sand lightly before painting.

STORAGE

HANDLE (See Figs. 25 and 26)

You can fold your lawn mower handle for storage.

1. Loosen the two (2) handle knobs on sides of the upper handle and allow handle to fold down to the rear.

2. Remove the two (2) handle knobs and carriage bolts on sides of the lower handle and pivot entire handle as sem bly forward and allow it to rest on mower.

3. Reinstall knobs and carriage bolts to lower handle or handle brackets for safe keeping.

• When setting up your handle from the storage position, the lower han dle will require manually locking into the mowing position.

FUEL SYSTEM

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, 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.

• Empty the fuel tank by starting the engine and letting it run until the fuel lines and car bu re tor 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 stor age.

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 empty the gas tank and carburetor if using fuel stabilizer.

ENGINE OIL

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

CYLINDER

1. Remove spark plug.

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

3. Pull starter handle slowly a few times to distribute oil.

4. Replace with new spark plug.

OTHER

• Do not store gasoline from one season to another.

• Replace your gasoline can 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 protective 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.

CAUTION: Never store the lawn mower with gasoline in the tank inside a build-

ing where fumes may reach an open fl ame or spark. Allow the engine to cool before storing in any enclosure.
