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.

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.

• 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 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 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.

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. Exer-

cise 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.

CONGRATULATIONS on your purchase of a new lawn mower. It has been designed, engineered and man u fac tured to

give you the best possible dependability and performance.

Should you experience any problem you cannot easily remedy, please contact your nearest authorized service center/

department. We have competent, well-trained tech ni cians and the proper tools to service or repair this lawn mower.

Please read and retain this manual. The instructions will enable you to assemble and maintain your lawn mower properly.

Always observe the “SAFETY RULES”.

MEETS CPSC SAFETY REQUIREMENTS

Husqvarna rotary walk-behind power lawn mowers conform to the safety standards of the American National Standards

Institute and the U.S. Consumer Product Safety Commission.

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 ex-

tremely 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 fuel container 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 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.

WARNING: This lawn mower is equipped with an

internal com bus tion engine and should not be

used on or near any un im proved forest-covered,

brush-covered or grass-cov ered 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.

A spark arrester for the muffler is available through

your nearest authorized service center.

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 dipstick from oil fill spout (Figure 15).

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.

IMPORTANT: Change the oil after every 25 hours of op-

eration 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.

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 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.

unnecessary wear.

MOWING TIPS

• Under certain conditions, such as very tall grass, it

may be nec es sary 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 re duce ground speed and/or run the lawn

mower over the area a sec ond time.

• For extremely heavy cutting, re duce the width of cut

by over lap ping previously cut path and mow slowly.

• For better grass bagging and most cutting conditions,

the engine speed should be set in the FAST po si tion.

• When using a rear discharge lawn mower in moist,

heavy grass, clumps of cut grass may not enter the

grass catcher. Reduce ground speed (pushing speed)

and/or run the lawn mower over the area a second

time.

• If a trail of clippings is left on the right side of a rear

discharge mow er, mow in a clockwise direction with a

small overlap to collect the clippings on the next pass.

• Pores in cloth grass catchers can become filled with

dirt and dust with use and catchers will collect less

grass. To prevent this, reg u lar ly 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.

CAUTION: Do not use de-thatcher blade

attachments on your mower. Such attachments

are hazardous, will damage your mower and could

void your warranty.

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 (Figure 19). 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.

• 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.

LUBRICATION CHART

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

mower 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

Ad just ments 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

1. Check engine oil level.

2. Check for loose fasteners.

LUBRICATION

Keep unit well lubricated (See “LUBRICATION CHART”).

IMPORTANT: DO NOT OIL OR GREASE PLASTIC WHEEL

BEARINGS. VISCOUS LU BRI CANTS WILL ATTRACT DUST

AND DIRT THAT WILL SHORT EN THE LIFE OF THE SELF-

LU BRI CAT ING BEARINGS. IF YOU FEEL THEY MUST BE

MAINTENANCE

LAWN MOWER

Always observe safety rules when performing any main-

te nance.

TIRES

• Keep tires free of gasoline, oil, or insect control chem i-

cals which can harm rubber.

• Avoid stumps, stones, deep ruts, sharp objects and

other hazards that may cause tire damage.

DRIVE WHEELS

Check rear drive wheels each time you mow to be sure they

move freely. The wheels not turning freely means trash,

grass cuttings, etc., may be inside the drive wheel and dust

cover area and must be cleaned out to free drive wheels.

If necessary to clean drive wheels, check both rear wheels.

BLADE CARE

For best results, mower blade must be kept sharp. Re place

bent or dam aged blades.

MAINTENANCE

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.

CAUTION: Protect your hands with gloves and/

or wrap blade with heavy cloth.

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 hous ing

to prevent blade from turning when re mov ing blade bolt.

4. Remove blade bolt by turning counter-clockwise

(Figure 20).

5. Remove blade and attaching hardware (bolt, lock

wash er and hardened wash er).

MAINTENANCE

TO SHARPEN BLADE

NOTE: We do not recommend sharp en ing blade - but if

you do, be sure the blade is balanced. An un bal anced

blade will cause eventual damage to lawn mower or engine.

• The blade can be sharp ened 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

bal anc er, follow the in struc tions supplied with bal anc er.)

NOTE: Do not use a nail for balancing blade. The lobes

of the center hole may appear to be centered, but are not.

1. 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 bal anced, it should remain in a horizontal

po si tion. If either end of the blade moves downward,

sharpen the heavy end until the blade is balanced

(Figure 21).

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. Give the lawn mower model

number when ordering.

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 filled 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.

LUBRICATION

Use only high quality detergent oil rated with API service

classification SG–SL. Select the oil's SAE viscosity

grade according to your expected operating temperature

(Figure 22).

NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve

starting in cold weather, and you should check your engine

oil level frequently to avoid possible engine damage from

running low on oil.

Change the oil after every 25 hours of operation or at least

once a year if the lawn 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.

MAINTENANCE

TO CHANGE ENGINE OIL

NOTE: Before tipping lawn mower to drain oil, empty fuel

tank by running engine until fuel tank is empty.

1. Disconnect spark plug wire from spark plug and place

wire where it cannot come in contact with plug.

2. Remove engine oil cap/dipstick; lay aside on a clean

surface.

3. Tip lawn mower on its side as shown and drain oil into

a suitable container. Rock lawn mower back and forth

to remove any oil trapped inside of engine (Figure 23).

4. Wipe off any spilled oil from lawn mower or side of

engine.

5. Slowly pour oil down the oil fill spout, stopping every

few ounces to check the oil level with the dipstick.

6. Stop adding oil when you reach the FULL mark on the

dipstick. Wait a minute to allow oil to settle.

7. Continue adding small amounts of oil, rechecking the

dipstick until oil level settles at FULL. DO NOT overfill,

or engine will smoke heavily from the muffler on startup.

8. Always be sure to retighten oil dipstick before starting

engine.

9. Re con nect spark plug wire to spark plug.

AIR FILTER

Your engine will not run properly using a dirty air filter.

Replace paper cartridge every 100 hours of operation or

every season, which ev er occurs first. Service air cleaner

more often under dusty conditions.

NOTE: The air cleaner system uses a pleated filter with

an optional pre-cleaner. The pre-cleaner can be washed

and reused.

1. Loosen the fastener that holds the cover. Remove the

cover (Figure 24).

2. Remove the pre-cleaner and the filter.

3. To loosen debris, gently tap the filter on a hard surface.

If the filter is excessively dirty, replace with a new filter.

4. Wash the pre-cleaner in liquid detergent and water.

Then allow it to thoroughly air dry. Do not oil the pre-

cleaner.

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 “PROD UCT SPEC I FI CA TIONS” section of this manual.

IN-LINE FUEL FILTER

The fuel filter should be replaced once each season. If fuel

filter becomes clogged, ob struct ing fuel flow to car bu re tor,

re place ment is re quired.

1. With engine cool, remove filter and plug fuel line sec tions

(Figure 25).

2. Place new fuel filter in position in fuel line with arrow

pointing towards carburetor.

3. Be sure there are no fuel line leaks and clamps are

properly positioned.

4. Immediately wipe up any spilled gasoline.

MUFFLER

Inspect and replace corroded muffler as it could create a

fire hazard and/or damage.

• 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 / wheels free of 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 shortened engine life.

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.
