EQUIPMENT
WARNING DANGER
• Use only ECHO approved attachments. Serious injury may result
from the use of a non approved attachment combination. Read
and comply with all safety instructions listed in this manual and
safety manual.
• ECHO, INC. will not be responsible for the failure of cutting
devices, attachments or accessories which have not been tested
and approved by ECHO.
Before operation a complete check of the unit must be performed;
• Check unit for loose/missing nuts, bolts and screws. Tighten and/or
replace as needed.
• Inspect fuel lines, tank and area around carburetor for fuel leaks. DO
NOT operate unit if leaks are found.
• Inspect shield for damage and ensure that the cut-off knife is
securely in place. Replace if either is damaged or missing.
• Check that the cutting attachment is firmly attached and in safe
operating condition.
• Check that front (loop) handle and optional shoulder/waist harness
are adjusted for safe, comfortable operation. See Assembly for
proper adjustment.
• Have repairs done only by an authorized ECHO Service Dealer.
• Do not use any attachment, accessory or replacement part unless it
is recommended in the Operator's Manual.
Spark Arrestor - Catalytic Muffler / Muffler
• The muffler or catalytic muffler controls the exhaust noise and
emissions. The spark arrestor screen prevents hot, glowing particles
of carbon from leaving the muffler. Make sure the spark arrestor
screen is in good repair and properly seated in the muffler. Keep
exhaust area clear of flammable debris. Avoid contact during and
immediately after operation.

FUEL
WARNING DANGER
FuelisVERYflammable.Useextremecarewhenmixing,storingor
handling, otherwise 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.
• DONOTfillfueltanksindoors.ALWAYSfillfueltanksoutdoors
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.
After Use;
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return
unused fuel to an approved fuel storage container. 3 m (10 ft.)
PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING DANGER
Trimmer/Brush Cutter users risk injury to themselves and others if the trimmer/brush cutter is used improperly and or
safety precautions are not followed. Proper clothing and safety gear must be worn when operating a trimmer.

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
animalspreventedfrom comingnearerthan15m(50ft.) whilethe
trimmerisinuse.
Operation
Use Proper Clothing & Equipment
• Before starting the unit, equip yourself and any other person working
within the 15 m (50 ft.) Safety Zone with the required Protective
Equipment and clothing.
WARNING DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can cause
serious injury or death.
AvoidHotSurfaces
• During operation, the bearing housing, and the muffler or catalytic
muffler cover area may become very hot. Avoid contact during and
immediatelyafteroperation.Alwayskeepexhaustareaclearof

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 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 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.
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 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.

UseShoulder/WaistHarness(P/N30100052131)Useofthe Shoulder/
Waist Harness is recommended for ALLTrimmer/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 reducing the possibility of blade
contact with the operators hands and feet by restricting trimmer
movement.
