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 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 whenever 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 are cooler.
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,becausetheminimumexposure,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.

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.
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
animalspreventedfrom coming nearerthan15m (50 ft.)whiletheunit
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
andimmediatelyafteroperation.
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
riskfordeveloping a RepetitiveStressInjury(RSI). An extremeRSIcondition is CarpalTunnelSyndrome(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.

BLADE SELECTION
WARNING DANGER
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 is designed for grass, garden debris and
thick weeds. DO NOT use this blade for brush or heavy woody growth,
19mm(3/4in.)diameterorlarger.

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,andremix.
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.
Afteruse
• 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.
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.
