A WARNING: This trimmer 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 ap- plicable 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 autho-

rized service center/department.

The operation of any trimmer can result in foreign objects thrown into

SAFETYGLASSES

the eyes, which can result in severe eye damage. Always wear safety

glasses or eye shields while operating your trimmer or performing any adjustments or repairs. We recommend a wide vision safety mask over

spectacles or standard safety glasses.

I. GENERAL OPERATION

• Read, understand, and follow all instruc- tions on the machine and in the manual

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 all parts of your body away from muffler and spinning line. A hot muffler

can cause serious burns.

• Only allow responsible individuals, who are familiar with the instructions, to oper-

ate the machine.

• Stay away from breakable objects, such as house windows, auto glass, green- houses, etc.

• Clear the area of objects such as rocks,

toys, wire, bones, sticks, etc., which could be picked up and thrown by the

spinning lines.

• Be sure the area is clear of other people before trimming, particularly small chil- dren and pets. Stop machine if anyone

enters the area.

• Wear appropriate clothing such as a long-sleeved shirt or jacket. Also wear

long trousers or slacks. Do not wear shorts.

• Do not wear loose clothing which could get caught in this equipment.

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

wear work gloves and sturdy footwear.

Leather work shoes or short boots work

well for most people. These will protect the operator's ankles and shins from

small sticks, splinters, and other debris, and improve traction.

• Do not pull machine backwards unless absolutely necessary. Always look down

and behind before and while moving

backwards.

• Do not operate the machine without

proper guards, plates or other safety protective devices in place.

• See manufacturer's instructions for prop- er operation and installation of accesso-

ries. Only use accessories approved by

the manufacturer.

• Never use blades, wire, or flailing de- vices. This unit is designed for line trim-

mer use only. Use of other accessories

or attachments will increase the risk of

injury.

• Stopthe rotatingtrimmerheadwhen crossinggraveldrives,walks,or roads. Waitfor thecuttinglinesto stop rotating.

• Stoptheengine(motor)wheneveryou leavethe equipmentandallowit tocool, beforecleaning,repairingor inspecting

theunit.Be surethe trimmer headand all movingpartshavestopped.

• Operateonlyin daylightor goodartificial light.

• Do not operatethe machinewhileunder theinfluenceofalcoholordrugs.

• Neveroperatemachinein wet grass. Alwaysbe sureof your footing:keepa

firm holdon the handleandwalk;never run.

• Ifthe equipmentshouldstart to vibrate abnormally,stop the engine(motor)and

checkimmediatelyforthe cause. Vibra- tion is generallya warningof trouble.

• Alwayswearsafetygogglesor safety glasseswithsideshieldswhen oper- atingmachine.

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 trim it.

DO:

• Trim 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 trim 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 trimming 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 moving 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

• Use extra care in handling gasoline and 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 en- gine to cool before refueling. Do not

smoke. Never refuel the machine indoors. Never store the machine or fuel con-

tainer inside where there is an open flame, such as a water heater.

Move away from fueling site before starting engine.

• 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 acci- dental starting.

• Keep nuts and bolts, especially trimmer head and engine 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 buildup. Clean oil or fuel

spillage. Allow machine to cool before

cleaning or storing.

• Stop and inspect the equipment if you strike an object. Repair, if necessary,

before restarting.

• Do not change the engine governor set-

ting or overspeed the engine.

• Clean and replace safety and instruction decals as necessary.

ALook for this symbol to point out

important safety precautions. It means

CAUTION!!! BECOME ALERT!!! YOUR SAFETY IS INVOLVED.

_L,WARNING: In order to prevent ac- cidental starting when setting up, trans-

porting, adjusting or making repairs, always disconnect spark plug wire and

place wire where it cannot contact spark plug.

A CAUTION: Muffler and other engine

parts become extremely hot during operation and remain hot after engine

has stopped. To avoid severe burns on

BEFORE STARTING ENGINE

ADD OIL

Your trimmer is shipped without oil in the engine. For type and grade of oil to use, see the engine maintenance section in

your engine manual. A CAUTION: DO NOT overfill engine with

oil, or it will smoke on startup.

1. Be sure trimmer is level and area around oil fill is clean.

2. Remove oil dipstick from oil fill spout. Make sure that rim of spout is clean.

3. You receive a container of oil with the unit. Slowly pour 3/4 (15 oz.) of the

oil from the container down the oil fill spout into the engine.

4. Wait one minute to allow oil to settle. Insert and tighten dipstick, then re-

move it to check oil level.

5. Continue adding small amounts of oil and rechecking the dipstick until it

reads full. DO NOT overfill, or engine

will smoke on startup.

6. Always be sure to retighten oil dipstick before starting engine.

• 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.

TECUMSEH MODELS:

Gasoline filler cap

ADD GASOLINE

• Fill fuel tank to bottom of gas 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 quanti- ties that can be used within 30 days to

assure fuel freshness.

• L,CAUTION: Wipe off any spilled oil or

fuel. Do not store, spill or use gasoline near an open flame.

_I, 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 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.

Use a firm push. This step is not usually necessary when starting an

engine which has already run for a few

minutes.

2. Move throttle control lever to fast posi- tion.

3. Hold upper handle firmly and pull starter handle quickly. Do not allow

starter rope to snap back.

TO STOP ENGINE

• To stop engine, move throttle control

lever to stop position.

NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather overpriming 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.

TRIMMING TIPS

• Set the throttle control in the fast posi- tion. If the weeds or grass are tall and

thick, operate the trimmer at a slower walking speed.

• Frequently clean the underside of the trimmer to remove any grass build up.

Keep top of engine around starter clear

and clean of grass clippings and chaff. This will help engine air flow and extend engine life. See "TO REMOVE ENGINE

COVER" in the Maintenance section of this manual.

• For best results and longer lasting line, use the ends of the line to do the

cutting. This is easily done by moving

slowly through very thick and heavy

weeds.

• Use the left side of trimmer when trim- ming along fences, walls, flowerbeds

and other such objects.

• If trimmer lines become too short, it will

take longer to complete the job. If trim-

mer lines are worn to less than half their original length, they should be replaced.

See "TO REPLACE TRIMMER LINE" in

the Maintenance section of this manual.

• Trimmer head contact with concrete, as- phalt or other hard surfaces may cause premature wear of the ball on bottom of

trimmer head.

GENERAL RECOMMENDATIONS

The warranty on this trimmer does not cover

items that have been subjected to operator abuse or negligence. To receive full value

from the warranty, operator must maintain trimmer as instructed in this manual.

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

All adjustments in the Service and Adjust-

ments section of this manual should be

checked at least once each season.

• Once a year, replace the spark plug and replace air filter element. 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.

3. Clean under engine cover.

LUBRICATION To prolong the useful life of your trimmer,

change engine oil as recommended in this section of Operator's Manual. 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.

TRIMMER

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.

TRIMMER LINE

For best results, replace trimmer lines

when they have worn to half their original

length.

20" models use .130 inch diameter trim-

mer line. Cut new trimmer line length to 16-3/4 inches.

22" models use .155 inch diameter trim-

mer line. Cut new trimmer line length to 18-3/4 inches.

After new line is installed on trimmer head, check all lines so they do not vary more then one (1) inch in length. This is im-

portant to make sure the trimmer head is

balanced and will not vibrate abnormally. AWARNING: Use only the specified trimmer line. Do not use other materials

such as wire, string, rope, etc. Wire can

break off during trimming and become a

dangerous missile that can cause serious

injury. TO CUT LINE TO PROPER LENGTH

NOTE: Trimmer line pre-cut to proper

length is available for this unit; see the

Repair Parts section of this manual.

If trimmer line is purchased in bulk, it must

be cut to length before using. Use the

built-in length guage as follows:

1. From front of trimmer, place the end of spooled trimmer line at the mark on the

side of the debris shield as shown.

2. Wrap trimmer line around front of chas- sis cover to other side and cut at the

mark (for your unit's width of cut).

AIR FILTER Your engine will not run properly and may

be damaged by using a dirty air filter. Replace the air filter every 100 hours of operation or every season, whichever oc-

curs first. Service air cleaner more often

under dusty conditions. Do not wash air

filter. Refer to engine manual.

MUFFLER Inspect and replace corroded muffler as it

could create a fire hazard and/or damage.

SPARK PLUG Change your spark plug each year to

make your engine start easier and run better. Set spark plug gap according to

engine manual specifications.

CLEAN UNDER ENGINE COVER

(TECUMSEH MODELS ONLY) Clean under engine cover before each

use, or more frequently in heavy cutting or

dirty conditions. Engine cover screen and engine air intake screen must be kept free

of dirt and chaff to prevent engine damage from overheating.

Be sure engine is cool before cleaning.

1. Unscrew knob on top of cover.

2. Lift cover up and away from engine.

3. Clean cover and cover screen thor- oughly.

4. Clean top of engine and air intake screen.

5. Replace engine cover and tighten

knob securely. Be sure the front tabs of engine cover are located in the slots in engine housing.

CLEANING

IMPORTANT: For best performance, keep trimmer free of built-up grass and

trash. Clean the underside of your trimmer

after each use.

• ilCAUTION: Disconnect spark plug wire from spark plug and place wire where it

cannot come in contact with the spark

plug.

• Turn trimmer on its side. Make sure air filter and carburetor are up. Clean the

underside of your trimmer 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 gar- den hose to clean trimmer 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.

ENGINE SPEED

Your engine speed has been factory

set. Do not attempt to increase engine speed or it may result in personal injury.

If you believe that the engine is running

too fast or too slow, take your unit to a

qualified service center for repair and/or adjustment.

CARBURETOR

Your carburetor has a nonadjustable fixed main jet for mixture control. If your engine does not operate properly due to

suspected carburetor problems, take your

Bolt

Flat idler

unit to a qualified service center for repair

and/or adjustment.

IMPORTANT: Never tamper with the

engine governor, which is factory set for

proper engine speed. Overspeeding

the engine above the factory high speed setting can be dangerous. If you think

the engine-governed high speed needs adjusting, take your unit to a qualified

service center, which has proper equipment and experience to make any

necessary adjustments.

Immediately prepare your trimmer for stor- age at the end of the season or if the unit

will not be used for 30 days or more. TRIMMER

When trimmer is to be stored for a period

of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dry

area.

1. Clean entire trimmer (See "CLEAN-

ING" in the Maintenance section of this manual).

2. Lubricate as shown in the Maintenance section of this manual.

3. Be sure that all nuts, bolts, screws, and

pins are securely fastened. Inspect moving parts for damage, breakage

and wear. Replace if necessary.

4. Touchup all rustedor chippedpaint surfaces;sandlightly beforepainting.

HANDLE

Youcan foldyourtrimmerhandlefor stor-

age.

• Loosenhandleknob enoughto allow

2. Start the engine and let it run until the fuel lines and carburetor are empty.

• Never use engine or carburetor cleaner

products in the fuel tank or permanent damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage.

Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix

ratio found on stabilizer container. Run engine at least 10 minutes after adding

stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank

and carburetor if using fuel stabilizer.

ENGINE OIL Drain oil (with engine warm) and replace

with clean engine oil. (See "ENGINE" in the Maintenance section of this manual).

CYLINDER

1. Remove spark plug.

2. Pour one ounce (29 ml) of oil through spark plug hole into cylinder.

3. Pull starter handle slowly a few times to distribute oil.

4. Replace with new spark plug.

Handle knob

ENGINE FUEL SYSTEM

IMPORTANT: It is important to prevent gum deposits from forming in essential

fuel system parts such as carburetor, fuel filter, fuel hose or tank during storage.

Also, 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.

1. Drain the fuel tank.

OTHER

• Do not store gasoline from one season

to another.

• Replace your gasoline can if your can

starts to rust. Rust and/or dirt in your gasoline will cause problems.

• If possible, store your unit indoors and

cover it to give protection from dust and

dirt.

• Cover your unit with a suitable protec-

tive cover that does not retain moisture.

Do not use plastic. Plastic cannot breathe, which allows condensation to

form and will cause your unit to rust.

IMPORTANT: Never cover trimmer while engine and exhaust areas are still warm.

_CAUTION: Never store the trimmer with gasoline in the tank inside a building

where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.
