- DO NOT WEAR TIES, SCARVES, JEWELRY.

Wear sturdy work shoes with non-skid soles;

- DO NOT WEAR OPEN TOED SHOES,

- DO NOT OPERATE UNIT BAREFOOTED.

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.

8

SAFE OPERATION

Determine Operation Area

• Provide all operators of this equipment with the operator's manual and
instructions for safe operation.

• Review the area to be trimmed. Look for hazards that could
contribute to unsafe conditions.

• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15M (50 ft.) while
the trimmer is in use.

Operation

Use Proper Clothing & Equipment

• Before starting the unit, equip yourself and any other person working
within the 15M (50 ft.) Safety Zone with the required Protective
Equipment and clothing.

W ARNING DANGER

Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can cause
serious injury or death.

15M

(50 ft.)

Avoid Hot Surfaces

• During operation, the drive shaft housing and the bearing housing,
and the muffler or catalytic muffler cover area may become very hot.
Avoid contact during and immediately after operation. Always keep
exhaust area clear of flammable debris

Keep A Firm Grip

• Hold the front and rear handles with both hands with thumbs and
fingers encircling the handles

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

GRASS TRIMMER/BRUSH CUTTER

EXTENDED OPERATION/EXTREME CONDITIONS

Vibration and Cold --

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
recommended 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
exercises during frequent work breaks and also by not smoking.

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

OPERATOR'S MANUAL

9

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
movement.

• Do exercises 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.

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, 3/4" in. (19 mm) diameter or larger.

OPERATOR'S MANUAL

21

Brush/Clearing Blade P/N 69500120331 is designed for cutting brush
and woody growth up to 76 mm (3 in.) diameter.

Use Shoulder/Waist Harness P/N 99944200200 Use of the Shoulder/
Waist Harness is recommended for ALL Trimmer/Brush Cutter use, not
just Blade operation. The Shoulder/Waist Harness when used in a
trimming operation with nylon line head suspends the trimmer from the
operator's shoulder and reduces operator fatigue.

During blade operation, the same fatigue reduction is achieved. Safety
to the operator is also enhanced by preventing blade contact with the
operators hands and feet by restricting trimmer movement.

NOTE

In case of Emergency, pull up on the Quick Release Collar to
disconnect the trimmer from the harness.

FUEL

Fuel Requirements

Gasoline - Use 89 Octane [ ] gasoline or gasohol known to be good
quality. Gasohol may contain up to 10% Ethyl (grain) alcohol or 15%
MTBE (methyl tertiary-butyl ether). Gasohol containing methyl (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 Standards, must be used. Echo brand Premium
50:1 oil meets these standards. Engine problems due to inadequate
lubrication caused by failure to use an ISO-L-EGD and J.A.S.O FC
cerified oil, such as Echo Premium 50:1 Two-stroke Oil, will void the two­stroke engine warranty. (Emission related parts only are covered for
two years, regardless of two-stroke oil used, per the statement listed in
the California Emission Defect Warranty Explanation.)

Mixing - Follow directions on the oil container.

Handling Fuel

W ARNING 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!

• NEVER refuel a unit with the engine running.

• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks

outdoors over bare ground.

• Securely tighten fuel cap after refueling.

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

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. Contact your ECHO dealer for ordering
information.

After refueling;

• Wipe any spilled fuel from the unit.

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

After use;

• DO NOT store a unit with fuel in its tank. Leaks can occur.
Return unused fuel to an approved fuel storage container.

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.

SHARPENING METAL BLADES

Three styles of metal blades are approved for use on the ECHO Brush
Cutter. The 8-tooth blade can be sharpened during normal mainte­nance. The clearing blade and 80 tooth blade require professional
service.

Before sharpening, CLOSELY inspect blade for cracks (look at the
bottom of each tooth and the center mounting hole closely), missing
teeth and bending. If ANY of these problems are discovered, replace
the blade.

When sharpening a blade, always remove the same amount of materials
from each tooth to maintain balance. A blade that is not balanced will
cause unsafe handling due to vibration and can result in blade failure.

8-tooth Blade

OPERATOR'S MANUAL

37

Tools required: Flat file (preferred), Electric grinder if special care is
used, Round (rat tail) file for gullet (radius).

1 . File each tooth at a 30 degree angle a specific number of times,

eg. 4 strokes per tooth. Work your way around the blade until
all teeth are sharp.

2 . DO NOT file the 'gullet' (radius) of the tooth with the flat file.

The radius must remain. A sharp corner will lead to a crack and
blade failure.

IMPORTANT

If an electric grinder is used, use care not to overheat teeth, do not
allow tips/tooth to glow red or turn blue. DO NOT place blade in
cooling water. This will change the temper of the blade and could
result in blade failure.

3. After sharpening teeth, check each tooth radius for evidence of a
square (sharp) corner. Use the round (rat tail) file to renew the
radius.
