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.

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 its con stit u ents, and certain vehicle com po nents contain or emit chem i 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

• 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.

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.

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.

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.

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.

• Never direct discharged material toward anyone.

Avoid discharging material against a wall or obstruction. Material may richochet back toward the operator.

Stop the blade when crossing gravel surfaces.

• 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.

2

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. SAFE HANDLING OF GASOLINE

Use extreme care in handling gasoline. Gasoline is extremely fl ammable and the vapors are explosive.

• Extinguish all cigarettes, cigars, pipes and other sources of ignition.

• Use only an approved container.

• Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling.

• Never refuel the machine indoors.

• Never store the machine or fuel container where there is an open fl ame, spark or pilot light such as a water heater or on other appliances.

• Never fi ll containers inside a vehicle, on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before fi lling.

• Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.

• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Do not use a nozzle lock-open device.

• If fuel is spilled on clothing, change clothing immediately.

• Never overfi ll fuel tank. Replace gas cap and tighten securely.

V. GENERAL SERVICE

• Never run a machine inside a closed area.

• Never make adjustments or repairs with the engine

(motor) running. Disconnect spark plug wire, and keep wire away from 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 blade is sharp and can cut. Wrap the blade or wear gloves, and use extra caution when servicing it.

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

• Maintain or replace safety and instruction labels, as necessary.

3. Engine holds 20 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. Insert and tighten dipstick, then remove it to check oil level.

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. 8)

• 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.

• 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.

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 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. 9). 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.

TO STOP ENGINE

• To stop engine, release operator presence con trol bar.

NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over priming may cause fl ooding and engine will not start. If you do fl ood engine, wait a few minutes before attempting to start and do not repeat priming steps.

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 product and should be considered normal.

1. To start a cold engine, push primer three (3) times before trying to start. Use a fi rm push. This step is not usually necessary when starting an engine which has already run for a few minutes.

2. Hold operator presence control bar down to the han dle and pull starter handle quickly. Do not allow starter rope to snap back.

8

MAX 1/3

FIG. 9

• 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–south one week, then change to east–west the next week. This helps prevent matting/graining of lawn.

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.

GEAR CASE

• To keep your drive system working properly, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under the drive cover twice a season.

• The gear case is fi lled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case.

• If lubricant is required, use only ELF Multis EP00. Do not sub sti tute.

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 mower model number when ordering.

• 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/wheels free of 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 spark plug wire from spark plug and place where it cannot come in contact with plug.

ENGINE

ENGINE SPEED

FIG. 16

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.

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

Maintenance section of this manual).

2. Lubricate as shown in 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.

HANDLE (See Figs. 17 and 18)

You can fold your lawn mower handle for storage.

1. Squeeze the bottom ends of the lower handle toward each other until the lower handle clears the handle bracket, then move handle forward.

2. Loosen upper handle mounting bolts enough to allow upper handle to be folded back.

IMPORTANT: WHEN FOLDING THE HANDLE FOR STORAGE

OR TRANSPORTATION, BE SURE TO FOLD THE HANDLE AS

SHOWN OR YOU MAY DAMAGE THE CONTROL CABLES.

• When setting up your handle from the storage position, the lower han dle will automatically lock into mow ing position.

ENGINE

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. 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 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 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).

• 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.
