EQUIPMENT
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 issecurely
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
immediatelyafteroperation.

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.
FUEL
WARNING DANGER
FuelisVERYflammable.Useextremecarewhenmixing,storingor

• Use an approved fuel container.
• DONOTsmokenearfuel.
• DONOTallow flamesorsparks nearfuel.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps
slowlyallowing pressure to equalize.
• NEVERrefuela unitwhenthe engineisHOT!

• 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
reducefuelspillage.ContactyourECHOdealerfor 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.)

Physical Condition --
Your judgment and physical dexterity may not be good:
• if you are tired or sick,
•ifyouaretakingmedication,
• 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 trimmer.
Hand Protection --
Wear no-slip, heavy duty work gloves to improve your grip on the
Trimmer/Brush Cutter handles. Gloves also reduce the transmission of
machine vibration to your hands.
Hearing Protection --
ECHO recommends wearing hearing protection whenever unit is used.
Proper Clothing --
Wear snug fitting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• DONOTWEARSHORTS,

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
animalspreventedfromcomingnearerthan15m(50ft.)while
thetrimmerisin use.
Operation
UseProperClothing&Equipment
• Before starting the unit, equip yourself and any other person
workingwithinthe15 m (50 ft.)SafetyZonewith 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.
KeepAFirmGrip
• Hold the front and rear handles with both hands with thumbs and
fingers encircling the handles
KeepASolidStance
• 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.
AvoidHotSurfaces
• During operation, the complete unit, especially the drive shaft
housing and the bearing housing may become very hot, too hot to
touch. Avoid contact during and immediately after operation.
15 m (50 ft.)

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
recommendedbecausethe minimum exposure whichmighttriggerthe
ailmentisunknown.
• 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).AnextremeRSIconditionisCarpalTunnelSyndrome
(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 & force in 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.

MAINTENANCE
WARNING DANGER
Do not perform maintenance on engine or muffler until engine and muffler are completely cool, otherwise serious
