I. GENERAL OPERATION

• Read, understand, and follow all instructions on the machine and in the

manual(s) before starting. Be thoroughly 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 dis-

charge 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 mowing. Stop machine if anyone

enters the area.

• Do not operate the mower when bare- foot or wearing open sandals. Always

wear substantial foot wear.

• Do not pull mower backwards unless absolutely necessary. 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 ap- proved 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 artificial light.

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

• Never operate machine in wet grass. Always be sure of your footing: keep a

firm hold on the handle and walk; never run.

• Disengage the self-propelled mech- anism 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. Vibra- tion is generally a warning of trouble.

• Always wear safety goggles or safety glasses with side shields when oper- ating 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 cau- tion. 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.

III. CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children.

Children are often attracted to the ma- chine and the mowing activity. Neveras-

sume 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.

• Use extra care when approaching blind

corners, shrubs, trees, or other objects that may obscure vision.

IV. SERVICE

other fuels. They are flammable 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 flame, such as a water heater.

• Never run a machine inside a closed area.

• Never make adjustments or repairs with the engine (motor) running. Disconnectthe spark plug wire, and keep the wire away from the plug topreventaccidental starting.

TO EMPTY GRASS CATCHER

1. Lift up on grass catcher using the frame handle.

2. Remove grass catcher with clippings from under lawn mower handle.

3. Empty clippings from bag using both frame handle and bag handle.

NOTE: Do not drag the bag when empty- ing; it will cause unnecessary wear.

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.

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. Wait until blade and

all moving parts have stopped and turn

fuel valve to OFF position if you do not

intend to restart the engine soon.

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.

1. Be sure fuel valve is in the ON position.

2. To start a cold engine, move handle

mounted throttle/choke control lever to CHOKE position.

3. Hold operator presence control bar

down to the handle and pull starter handle quickly. Do not allow starter rope to snap back.

4. Slowly move throttle control lever to

FAST position after engine starts.

• To start a warm engine, move throttle control lever to FAST position, then fol- low steps above.

• 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 Mainte-

nance 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.

Fuel valve lever

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 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 incloth grass catchers can be-

come 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.

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 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 change to east to west the next week. This will help prevent matting and graining of the lawn.

GENERAL RECOMMENDATIONS

The warranty on this lawn mower does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must

maintain unit as instructed in this manual.

Some adjustments will need to be made periodically to properly maintain your unit.

At least once a season, check to see if you should make any of the adjustments

described in the Service and Adjustments section of this manual.

• At least once a year, replace the spark plug, clean or replace air filter element and check blade for wear. A new spark plug and clean/new air filter element assure proper air-fuel mixture and help your engine run better and last longer.

• Follow the maintenance schedule in this manual.

BEFORE EACH USE

• Check engine oil level.

• Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See "LUBRICATION CHART').

IMPORTANT: Do not oil or grease plastic wheel bearings. Viscous lubricants will

attract dust and dirt that will shorten the life of the self-lubricating bearings. If you feel they

must be lubricated, use only a dry, powdered graphite type lubricant sparingly.

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 rub-

ber.

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

BLADE CARE For best results, mower blade must be

kept sharp. Replace bent or damaged blades.

TO REMOVE BLADE

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 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 hard- ware (bolt, lock washer and 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 aligning the two (2) holes in the blade with the raised lugs on the adapter.

3. Be sure the trailing edge of blade (op- posite 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. Ibs.

IMPORTANT: Blade bolt is heat treated. If bolt needs replacing, replace only with

approved bolt shown in the Repair Parts section of this manual.

TO SHARPEN BLADE NOTE: We do not recommend sharpening

blade - but if you do, be sure the blade is balanced.

Care should be taken to keep the blade 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, drive a nail into a beam or wall. Leave about one inch of

the straight nail exposed. 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 dam- age or deterioration. Through normal

use it will wear. If catcher needs replac- ing, replace only with approved replace- ment 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 classification SF-SJ. Select the

oil's SAE viscosity grade according to your expected operating temperature.
