SAFETYINSTRUCTIONS
PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING DANGER
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.
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,becausethe minimumexposure,which mighttriggerthe
ailment,isunknown.
• 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 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.
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
ECHOrecommendswearinghearingprotectionwhenever
unit is used.
Proper Clothing
Wear snug fitting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• DONOTWEARSHORTS,
• DONOTWEARTIES,SCARFS,JEWELRY.
Wear protective hair covering to contain long hair.
Wear sturdy work shoes with nonskid soles;
• DONOTWEAROPENTOEDSHOES,
• DONOTOPERATEUNITBAREFOOTED.
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
arecooler.

EQUIPMENT
WARNING DANGER
Use only ECHO approved attachments. Serious injury may result from the use of a non-approved attachment
combination. ECHO, INC. will not be responsible for the failure of cutting devices, attachments or accessories which
have not been tested and approved by ECHO. Read and comply with all safety instructions listed in this manual and
safety manual.
• 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 shoulder strap/ or shoulder/
waist harness are adjusted for safe, comfortable operation. See
Assembly Section for proper adjustment.
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 expo-
sure 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 grasp-
ing, 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 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.

The restrictive harness enhances operator safety by reducing the
possibility of blade contact with the operator's hands and feet.
NOTE
In case of Emergency, pull up on the Quick Release Collar to
disconnect the trimmer from the harness.

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.ContactyourECHOdealerfor
orderinginformation.
AfterRefueling
• Wipe any spilled fuel from the unit.
• Moveatleast3 m (10 ft.) fromrefueling
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.
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, unoccupied building,
away from sparks and flames. Do not store
fuel longer than 30 days.
IMPORTANT
Storedfuelages. Do notmixmorefuel
than you expect to use in thirty (30)
days, ninety (90) days when a fuel
stabilizerisadded.
IMPORTANT
Stored two-stroke fuel may separate.
ALWAYS shake fuel container thor-
oughly before each use.
FUEL
Fuel Requirements
Gasoline-Use 89Octane[R+M/2](mid gradeorhigher) gasoline
known to be good quality. Gasoline may contain up to 15% MTBE
(methyl tertiary-butyl ether). Gasohol containing methyl (wood) alcohol
is NOT approved.
TwoStrokeOil-Atwo-strokeengineoilmeetingISO-L-EGD(ISO/CD
13738)andJ.A.S.O.FC Standards must beused. Echo brand premium
Power Blend TM Universal 2-Stroke Oil meets these standards. Engine
problems due to inadequate lubrication caused by failure to use an
ISO-L-EGDandJ.A.S.O.FCcertifiedoil,suchasEchopremiumPower
BlendTM,will voidthetwo-stroke enginewarranty. (Emissionrelated
parts only are covered for two years, regardless of two-stroke oil used,
per the statement listed in the Emission Defect Warranty Explanation.)
IMPORTANT
EchopremiumPowerBlendTM Universal2-StrokeOilmaybemixed
at 50:1 ratio for application in all Echo engines sold in the past
regardless of ratio specified in those manuals.
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. Addremaininggasolineandremix.
5. Install fuel container cap and wipe any spilled fuel from container
and surrounding area.

Your ECHO unit is designed to provide many hours of trouble free service. Regular scheduled maintenance will help
your unit achieve that goal. If you are unsure or are not equipped with the necessary tools, you may want to take your
unit to an ECHO Service Dealer for maintenance. To help you decide whether you want to DO-IT-YOURSELF or have
the ECHO Dealer do it, each maintenance task has been graded. If task is not listed, see your ECHO Dealer for repairs.
SKILL LEVELS
Level1= Easy to do. Most required tools come with unit.
Level2= Moderate difficulty. Some specialized tools may be required.
Level3= Experience required. Specialized tools are required. Echo recommends that the unit be returned to your
ECHOdealerforservice.
ECHO offers REPOWERTM Maintenance Kits and Parts to make your maintenance job easier. Just below each task
heading are listed the various part numbers required for that task. See your ECHO dealer for these parts.
