Physical Condition

Your judgment and physical dexterity may not be good:

• if you are tired or sick,

• if you are taking medication,

• if you have taken alcohol or drugs.

Operate unit only if you are physically and mentally

well.

Eye Protection

Wear eye protection that meets ANSI Z87.1 or CE

requirements whenever you operate the unit.

Hand Protection

Wear no-slip, heavy-duty work gloves to improve your

grip on the handle. Gloves also reduce the transmission

of machine vibration to your hands.

Hearing Protection

ECHO recommends wearing hearing protection when-

ever unit is used.

Extended Operation/Extreme Conditions

It is believed that a condition called Raynaud’s Phenomenon, which affects the fingers of certain individuals, may be

brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning

sensations, followed by loss of color and numbness in the fingers. The following precautions are strongly recom-

mended, because the minimum exposure, which might trigger the ailment, is unknown.

• Keep your body warm, especially the head, neck, feet, ankles, hands,

and wrists.

• Maintain good blood circulation by performing vigorous arm exer-

cises during frequent work breaks, and also by not smoking.

• Limit the hours of operation. Try to fill each day with jobs where

operating the unit or other hand-held power equipment is not

required.

• If you experience discomfort, redness, and swelling of the fingers

followed by whitening and loss of feeling, consult your physician

before further exposing yourself to cold and vibration.

PERSONAL CONDITION AND SAFETY EQUIPMENT

WARNING

Users of this product risk injury to themselves and others if the unit is used improperly and/or safety precautions

are not followed. Proper clothing and safety gear must be worn when operating unit.

Proper Clothing

Wear snug fitting, durable clothing;

• Pants should have long legs, shirts with long sleeves.

• DO NOT WEAR SHORTS,

• DO NOT WEAR TIES, SCARFS, JEWELRY.

Wear protective hair covering to contain long hair.

Wear sturdy work shoes with nonskid soles;

• DO NOT WEAR OPEN TOED SHOES,

• DO NOT OPERATE UNIT BAREFOOTED.

Keep long hair away from engine and air intake. Retain

hair with cap or net.

Hot Humid Weather

Heavy protective clothing can increase operator fatigue

which may lead to heat stroke. Schedule heavy work for

early morning or late afternoon hours when temperatures

are cooler.

DANGER

Do not operate this product indoors or in inadequately ventilated

areas. Engine exhaust contains poisonous emissions and can

cause serious injury or death.

Read the Manuals

• Provide all users of this equipment with the Operator’s Manual and

Safety Manual for instructions on Safe Operation.

Clear the Work Area

• Spectators and fellow workers must be warned, and children and

animals prevented from coming nearer than 15 m (50 ft.) while the unit

is in use.

Keep a Firm Grip

• Hold the front and rear handles with both hands, with thumbs and

fingers encircling the handles.

Keep a Solid Stance

• Maintain footing and balance at all times. Do not stand on slippery,

uneven or unstable surfaces. Do not work in odd positions or on

ladders. Do not over reach.

Avoid Hot Surfaces

• Keep exhaust area clear of flammable debris. Avoid contact during

and immediately after operation.

Repetitive Stress Injuries

It is believed that overusing the muscles and tendons of the fingers, hands, arms, and shoulders may cause soreness,

swelling, numbness, weakness, and extreme pain in those areas. Certain repetitive hand activities may put you at a high

risk for developing a Repetitive Stress Injury (RSI). An extreme RSI condition is Carpal Tunnel Syndrome (CTS), which

could occur when your wrist swells and squeezes a vital nerve that runs through the area. Some believe that prolonged

exposure to vibration may contribute to CTS. CTS can cause severe pain for months or even years.

To reduce the risk of RSI/CTS, do the following:

• Avoid using your wrist in a bent, extended, or twisted position.

Instead try to maintain a straight wrist position. Also, when grasping,

use your whole hand, not just the thumb and index finger.

• Take periodic breaks to minimize repetition and rest your hands.

• Reduce the speed and force with which you do the repetitive move-

ment.

• Do exercise to strengthen the hand and arm muscles.

• Immediately stop using all power equipment and consult a doctor if

you feel tingling, numbness, or pain in the fingers, hands, wrists, or

arms. The sooner RSI/CTS is diagnosed, the more likely permanent

nerve and muscle damage can be prevented.

Choosing the Correct Blade

WARNING

The type of Blade used MUST be matched to the type and size of material cut. An improper or dull blade can

cause serious personal injury. Blades MUST be sharp. Dull blades increase the chance of kick-out and injury to

yourself and bystanders.

Plastic/Nylon Blades may be used where ever the nylon line head

is used. DO NOT use this blade for heavy weeds or brush!

8 Tooth Weed/Grass Blade (P/N 69600120331) is designed for grass,

garden debris and thick weeds. DO NOT use this blade for brush or

heavy woody growth, 19 mm (3/4 in.) diameter or larger.

80 Tooth Brush Blade (P/N 69500120331) is designed for cutting

brush and woody growth up to 13 mm (1/2 in.) diameter.

22 Tooth Clearing Blade (99944200130) is designed for dense

thickets and saplings up to 64 mm (2-1/2 in.) diameter.

Use Shoulder/Waist Harness (P/N 99944200200) Use of the

Shoulder/Waist Harness is recommended for ALL Trimmer/Brush

Cutter use. The Shoulder/Waist Harness suspends the trimmer from

the operator's shoulder and reduces operator fatigue.

The restrictive harness enhances operator safety by reducing the

possibility of blade contact with the operator's hands and feet.

14

FUEL

NOTICE: Use of unmixed, improperly mixed, or fuel older than 90 days, (stale fuel), may cause hard starting,

poor performance, or severe engine damage and void the product warranty. Read and follow instructions in the

Storage section of this manual.

WARNING

Alternative fuels, such as E-20 (20% ethanol), E-85 (85% ethanol) or any fuels not meeting above requirements

are NOT approved for use in ECHO 2-stroke gasoline engines. Use of alternative fuels may cause performance

problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited

to, improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel lines, gaskets,

carburetors and other engine components.

Fuel Requirements

Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain up to

10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood alcohol) is

NOT approved.

Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC/FD Standards must

be used. Echo brand premium Power Blend X

TM

Universal 2-Stroke Oil meets these standards. Engine problems due to

inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC/FD certified oil, such

as Echo premium Power Blend X

TM

, will void the two-stroke engine warranty.

IMPORTANT

Echo premium Power BlendX

TM

Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo

engines sold in the past regardless of ratio specified in those manuals.

Handling Fuel

DANGER

Fuel is VERY flammable. Use extreme care when mixing, storing or handling or serious personal injury may

result.

• Use an approved fuel container.

• DO NOT smoke near fuel.

• DO NOT allow flames or sparks near fuel.

• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.

• NEVER refuel a unit when the engine is HOT or RUNNING!

• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.

• DO NOT overfill fuel tank. Wipe up spills immediately.

• Securely tighten fuel tank cap and close fuel container after refueling.

• Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.

• Move at least 3m (10 ft.) from refueling location before starting the engine.

GRASS TRIMMER/BRUSH CUTTER

OPERATOR'S MANUAL

15

Mixing Instructions

1. Fill an approved fuel container with half of the required amount of

gasoline.

2. Add the proper amount of 2-stroke oil to gasoline.

3. Close container and shake to mix oil with gasoline.

4. Add remaining gasoline, close fuel container, and remix.

IMPORTANT

Spilled fuel is a leading cause of hydrocarbon emissions. Some

states may require the use of automatic fuel shut-off containers to

reduce fuel spillage.

After use

• DO NOT store a unit with fuel in its tank. Leaks can occur. Return

unused fuel to an approved fuel storage container.

Storage - Fuel storage laws vary by locality. Contact your local

government for the laws affecting your area. As a precaution, store fuel

in an approved, airtight container. Store in a well-ventilated, unoccu-

pied building, away from sparks and flames.

IMPORTANT

Stored fuel ages. Do not mix more fuel than you expect to use in

thirty (30) days, ninety (90) days when a fuel stabilizer is added.

IMPORTANT

Stored two-stroke fuel may separate. ALWAYS shake fuel con-

tainer thoroughly before each use.

AIR FILTER

Level 1.

Tools Required: Cleaning brush 25 or 50 mm (1 or 2 in.)

Parts Required: REPOWER

TM

AIR & FUEL FILTER KIT.

1. Close choke (Cold Start Position [ ]). This prevents dirt from

entering the carburetor throat when the air filter is removed. Brush

accumulated dirt from air cleaner area.

2. Remove air filter cover. Brush dirt from inside cover.

3. Remove air filter and lightly brush debris from filter. Replace filter if

it is damaged, fuel soaked, very dirty, or the rubber sealing edges

are deformed.

4. If filter can be reused, be certain it:

• Fits tightly in the air filter cavity.

• Is installed with the original side out.

5. Install air filter cover.

FUEL FILTER

Level 1.

Tools Required: 200-250 mm (8 -10 in.) length of wire with one end bent

into a hook, clean rag, funnel, and an approved fuel

container.

Parts Required: REPOWER

TM

AIR & FUEL FILTER KIT.

DANGER

Fuel is VERY flammable. Use extreme care when mixing, storing

or handling.

1. Use a clean rag to remove loose dirt from around fuel cap and

empty fuel tank.

2. Use the “fuel line hook” to pull the fuel line and filter from the

tank.

3. Remove the filter from the line and install the new filter.

SPARK PLUG

Level 2.

Tools Required: T-Wrench, feeler gauge, soft metal brush.

Parts Required: REPOWER

TM

Tune-Up Kit

IMPORTANT

Use only NGK BPM-8Y spark plug (BPMR-8Y in Canada) otherwise

severe engine damage may occur.

1. Remove spark plug and check for fouling, worn and rounded

center electrode.

2. Clean the plug or replace with a new one. DO NOT sand blast to

clean. Remaining sand will damage engine.

3. Adjust spark plug gap by bending outer electrode.

4. Tighten spark plug to 150-170 kgf • cm (130-150 in • lbf).

COOLING SYSTEM

Level 2.

Tools Required: 4 mm Hex Wrench, cleaning brush, 25 or 50 mm

(1 or 2 in.)

Parts Required: None if you are careful.

IMPORTANT

To maintain proper engine operating temperatures, cooling air

must pass freely through the cylinder fin area. This flow of air

carries combustion heat away from the engine.

Overheating and engine seizure can occur when:

• Air intakes are blocked, preventing cooling air from reaching the

cylinder.

• Dust and grass build up on the outside of the cylinder. This build up

insulates the engine and prevents the heat from leaving.

Removal of cooling passage blockages or cleaning of cooling fins is

considered “Normal Maintenance.” Any failure attributed to lack of

maintenance is not warranted.
