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 equipment, 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 catcher.

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 onmowerssoequippedbeforestartingtheengine(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:

Mowacrossthefaceofslopes:neverupanddown. Exercise extreme cautionwhenchangingdirectionon 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.

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 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 machine.

BEFORE STARTING ENGINE

ADD OIL (See Fig. 9)

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.

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 fi ll spout into the engine.

NOTE: Initial oil fi ll 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 Maintenance section of this manual.

GASOLINE

OIL FILL CAP/

FILLER CAP

DIPSTICK

FIG. 9

ADD GASOLINE (See Fig. 9)

Fill fuel tank to bottom of tank fi ller neck. Do not over- fi ll. 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.

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

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. 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 presence 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.

NOTE: Your engine is equipped with an automatic choke system. No priming or choking is required before starting.

To start engine, hold operator presence control bar down to the handle and pull starter handle quickly. Do not allow starter rope to snap back.

OPERATION

MOWING TIPS

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 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.

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. 10). 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.

MAX 1/3

FIG. 10

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 first cut path.

Change your cutting pattern from week to week. Mow north to south one week then east to west the next week. This will help prevent matting and graining of the lawn.

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 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 front wheels.

1.Remove hubcaps, locknuts and 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 qualified service center.

IMPORTANT: TO ENSURE PROPER ASSEMBLY, CENTER HOLE IN BLADE MUST ALIGN WITH STAR ON BLADE ADAPTER.

3.Be sure the 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.

TO SHARPEN BLADE (See Fig. 12)

NOTE: We do not recommend sharpening 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 fi le 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 balancer.)

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.

SPARK PLUG

Replace spark plug at the beginning of each mowing season or after every 100 hours of operation, whichever occurs fi rst. Spark plug type and gap setting are shown in the “PRODUCT SPECIFICATIONS” section of this manual.

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 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 / wheels free of gasoline, oil, etc.

We do not recommend using a garden hose to clean lawn mower unless the electrical system, muffler, 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.

WATER WASHOUT FEATURE (See Fig. 15)

Your lawn mower is equipped with a fi tting that allows quick and easy cleaning of the underside of the housing. To use this feature, proceed as follows:

1.Move lawn mower to an area of cut grass or another hard surface.

NOTE: Water, grass and other debris will drain from beneath the mower housing during the washout process.

2.Remove grass catcher and discharge chute assembly from lawn mower.

3.Close mulcher door (if equipped).

4.Connect a garden hose to the fitting where shown.

IMPORTANT: BE SURE THE GARDEN HOSE IS NOT ROUTED UNDER THE LAWN MOWER HOUSING OR ENTANGLED IN THE WHEELS.

5.Turn on water supply and check for leaks at the fi t- ting.

If no leaks are present, start engine (as described in the Operation section of this manual) and let engine run until the underside of the lawn mower is clean.

WARNING: Do not engage the drive system during the washout process.

6.Shut off the engine.

7.Shut off water supply and remove hose from fitting.

CAUTION: Do not remove hose from fitting while engine is running. Water in engine can result in shortened engine life.

8.Start engine (as described in the Operation section of this manual) and let engine run for a full minute to remove excess water from mower.
