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

wear substantial foot wear.

• Do not pull mower backwards unless abso-

lutely necessary. Always look down and be- hind before and while moving backwards.

• Never direct discharged material toward

anyone. Avoid discharging material against awall or obstruction. Material may

richochet back toward the operator. Stop

the blade when crossing gravel surfaces.

• Do not operate the mower without prop-

er 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.

• Mowonlyin 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; walk, never run.

• Disengage the self-propelled mech-

anism or drive clutch on mowers so equipped before starting the engine.

• 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.

• AIwayswearsafety goggles or safety glass-

eswith side shieldswhen operating mower.

Ii. SLOPE OPERATION

Slopes are a major factor related to slip & fall accidents which can result in severe

injury. All slopes require extra caution. If

2 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 machine and the

mowing activity. Neverassume 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 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 flammable 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 fue! 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.

GENERAL SERVICE

Never run 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 spill-

age. Allow machine to coo! 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 allowobjects to be thrown. Frequently check compo- nents 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.

Inthe state of California the above is required by law (Section 4442 ofthe 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 Husqvarna or other authorized service 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. _, CAUTION: DO NOT overfill engine with oil, or it will smoke on startup.

1. Be sure lawnmower is level.

2. Remove oil fill cap/dipstick from spout.

3. You recieve a container of oil with the

unit. Slowly pour the entire container down the oil fill spout into the engine.

4. Insert and tighten oil fill cap/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 gasoho! 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.

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. Pur-

chase fuel in quantities that can be used

within 30 days to assure fuel freshness.

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 methanol) can

attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system ofan 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 carburetorare empty. Use fresh fuel next season. See Storage Instructions for additional information. Neveruse engine

or carburetor cleaner products in the fuel tank or permanent damage may occur.

MOWING TIPS

CAUTION: Do not use de-thatcher

blade attachments on your mower. Such attachments are hazardous, wil! 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 yourwidth of cut by overlap- ping previously cut path and mow slowly.

MAX 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 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

10 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 wil! 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.

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.

BLADE CARE

For best results, mower blade must be kept sharp. Replace bent or damaged blades. 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

hazardous, 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, Iockwasher and hardened washer).

TO REPLACE BLADE

1. Position blade on the blade adapter aligning the two (2) holes in the blade

with the raised lugs on the adapter.

2. Be sure the trailing edge of blade (oppo- site sharp edge) is up toward the engine.

3. Install the blade bolt with the lock

washer and hardened washer into

blade adapter and crankshaft.

4. Use block of wood between blade and lawn mower housing and tighten the

blade bolt, turning clockwise.

ening the 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, 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.

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.
