II.SLOPE OPERATION
Slopes are a major factor related to slip & fall accidents which can result in severe in jury. 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 foot ing 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. A/everassume that children will remain where you last saw them.
•Keep children out of the trimming area and under the watchful care of another responsible 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 ma chine.
•Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.
IV. SAFE HANDLING OF GASOLINE

•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 contain er where there is an open flame, spark or pilot light such as a water heater or on other appliances.
•Never fill 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 filling.
•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 overfill 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 the spark plug wire, and keep the wire away from the plug to prevent accidental starting.
Keep nuts and bolts, especially blade attachment bolts, tight and keep equip ment 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 is running. Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturer’s recommended 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 set ting or overspeed the engine.
Maintain or replace safety and instruc tion labels, as necessary.
AWARNING: This lawn mower is equipped with an internal combustion engine and should not be used on or near any unimproved forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it should be maintained in effective working order by the operator.
In the state of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester for the muffler is available through your nearest Sears Parts & Repair Center (See the REPAIR PARTS section of this manual).

BEFORE STARTING 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.
A CAUTION: DO NOT overfill engine with oil, or it will smoke heavily from the muffler on startup.
1.Be sure lawnmower is level.
2.Remove oil dipstick from oil fill spout.
3.You receive a container of oil with the
unit. Slowly pour the entire container down the oil fill spout into the engine.
NOTE: Initial oil fill requires only 18 oz. due to residual oil in engine from the manufacturers 100% quality testing. When changing oil you may need 20 oz.
4. Insert and tighten dipstick.
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 ENGINE OIL” in the Mainte nance section of this manual.
ADD GASOLINE
•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.
A CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.
A CAUTION: 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 product and should be considered normal.
1.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.
2.Hold operator presence control bar down to the handle and pull starter handle quickly. Do not allow starter rope to snap back.
NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over priming may cause flooding and engine will not start. If you do flood engine, wait a few minutes before attempting to start and do not repeat priming steps.
10
MOWING TIPS
A CAUTION: Do not use de-thatcher blade attachments on your mower. Such attachments are hazardous, will damage
your mower and could void your warranty.
•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 cut ting conditions, the engine speed should be set in the FAST position.
•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. 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 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.
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 then change to east to west the next week. This will help prevent matting and graining of the lawn.

IMPORTANT: Do not oil or grease plastic wheel bearings. Viscous lubricants will attract dust and dirtthatwill shorten the life of the self-lubricating bearings. If you feel they must be lubricated, use only a dry, powdered
graphite type lubricant sparingly.
12
LAWN MOWER
Always observe safety rules when per forming any maintenance.
TIRES
•Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber.
•Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.
DRIVE WHEELS
Check front drive wheels each time before you mow to be sure they move freely.
The wheels not turning freely means trash, grass cuttings, etc. are inthe drive wheel area and must be cleaned to free drive wheels.
If necessary to clean the drive wheels, be sure to clean both front wheels.
1.Remove hubcaps, locknuts & washers.
2.Remove wheels from wheel adjusters.
3.Remove any trash or grass cuttings from inside the dust cover, pinion and/ or drive wheel gear teeth.
4.Put wheels back in place.
NOTE: If after cleaning, the drive wheels do not turn freely, contact a Sears or other qualified service center.
BLADE CARE
For best results, mower blade must be kept sharp. Replace a bent or damaged blade. A CAUTION: Use only a replacement
blade approved by the manufacturer of your mower. Using a blade not approved by the manufacturer of your mower is haz ardous, could damage your mower and void your warranty.
TO REMOVE BLADE
1.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.
2.Turn lawn mower on its side. Make sure air filter and carburetor are up.
3.Use a wood block between blade and mower housing to prevent blade from turning when removing blade bolt.
NOTE: Protect your hands with gloves and/or wrap blade with heavy cloth.
4.Remove blade bolt by turning counter clockwise.
5.Remove blade and attaching hardware
(bolt, lock washer, hardened washer). NOTE: Remove the blade adapter and check the key inside hub of blade adapter. The key must be in good condition to work properly. Replace adapter if damaged. TO REPLACE BLADE
1.Position the blade adapter on the en gine crankshaft. Be sure key in adapter and crankshaft keyway are aligned.
2.Position blade on the blade adapter.
IMPORTANT: To ensure proper assembly, center hole in blade must align with star on blade adapter.
3.Be sure trailing edge of blade (opposite sharp edge) is up toward the engine.
4.Install the blade bolt with the lock washer and hardened washer into blade adapter and crankshaft.
5.Use block of wood between blade and lawn mower housing and tighten the blade bolt, turning clockwise.
• The recommended tightening torque is 35-40 ft. lbs.

TO SHARPEN BLADE
NOTE: We do not recommend sharp ening blade - but if you do, be sure the blade is balanced. An unbalanced blade will cause eventual damage to lawn mower or engine.
•The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower.
•To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer
follow the instructions supplied with it.) NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not.
•Slide blade on to an unthreaded portion of the steel bolt or pin and hold the
bolt or pin parallel with the ground. 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.

NOTE: Although multi-viscosity oils |
|
(5W30, 10W30 etc.) improve starting in |
|
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 oil after every 25 hours of op |
|
eration orat least once a year if the mower |
|
is not used for 25 hours in one year. |
|
Check the crankcase oil level before |
|
starting the engine and after each five (5) |
|
hours of continuous use. Tighten oil plug |
|
securely each time you check the oil level. |

SPARK PLUG
Replace spark plug at the beginning of each mowing season or after every 100 hours of operation, whichever occurs first. Spark plug type and gap setting are shown in the “PRODUCT SPECIFIC ATIONS” section of this manual.
CLEANING
IMPORTANT: For best performance, keep mower housing free of built-grass and trash. Clean the underside of your mower after each use.
ACAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with 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 finished 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, muffler, air filter and carburetor are covered to keep water out. Water in engine can result in short ened 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.
