PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING
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.

4
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 sen-
sations, 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 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 require-
ments whenever you operate the unit.
Hand Protection
Wear no-slip, heavy-duty work gloves to improve your grip
on the blower handle. Gloves also reduce the transmission of
machine vibration to your hands.
Breathing Protection
Wear a facemask to protect against dust.
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.
• DO NOT WEAR SHORTS,
• DO NOT WEAR TIES, SCARVES, JEWELRY,
or clothing with loose or hanging items that could
become entangled in moving parts or surrounding
growth..
Wear sturdy work shoes with nonskid soles;
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
Wear no-slip, heavy duty work gloves.
Keep long hair away from engine and air intake. Retain
hair with cap or net.
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.
WARNING
The ignition components of this machine generate an electromagnetic field during operation which may interfere
with some pacemakers. To reduce the risk of serious or fatal injury, persons with pacemakers should consult with
their physician and the pacemaker manufacturer before operating this machine. In the absence of such informa-
tion, ECHO does not recommend the use of ECHO products by anyone who has a pacemaker.

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
for instructions on Safe Operation.
Clear the Work Area
• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15 m (50 ft.) while
the unit is in use.
• Take wind conditions into account: avoid open doors and win-
dows.
• Do not point blower at people or animals.
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 slip-
pery, 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 dur-
ing and immediately after operation.
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 doc-
tor 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.

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, and remix.
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.
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 gov-
ernment 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
Stored fuel ages. Do not mix more fuel than you expect to use in
thirty (30) days, ninety (90) days when a fuel stabilizer is added.

OPERATING BLOWER
WARNING
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a
poison gas. Breathing CO can cause unconsciousness, serious in-
jury, or death. Exhaust can cause serious burns. ALWAYS position
unit so that exhaust is directed away from your face and body.
WARNING
Always wear safety glasses, hearing protection, a face filter mask
and take all safety precautions or serious personal injury may result.
Do not point the blower pipe in the direction of people or pets.
IMPORTANT
Use reduced speed only when performing light-duty tasks or to
comply with local noise regulations. Continuous low speed opera-
tion may allow fuel/oil residue to build-up on the piston and cause
rapid build-up of carbon on the spark arrestor screen, resulting in
overheating and engine damage. To reduce harmful build-up, run
engine at wide open throttle for at least 5 minutes every hour, and
inspect/clean the spark arrestor screen after approximately 40 hours
of operation.
Read the Safety Section carefully.
IMPORTANT
To avoid engine damage due to over-revving, do not block
blower pipe opening.
1. Use only during appropriate hours.
2. Make sure all blower pipes are installed.
3. Allow the engine to warm up at a fast idle for a few minutes.
4. Set engine speed with throttle (A).
5. Use lower speed to blow dry grass and leaves from walks, patios
and drives.
6. Additional speed may be necessary to clean leaves from a lawn or
flower bed.
7. Higher speed may be necessary to move gravel, dirt, snow, bottles
or cans from a driveway, street, parking lot or stadium.
NOTE
Never use a higher speed setting than necessary to perform a task.
Remember, the higher the engine speed, the louder the blower
noise. Minimize dust by using blower at lower speeds and by
dampening material with water/mist when necessary. Keep debris
on your property.
Be Smart - be a good neighbor.

AIR FILTER
Level 1.
Parts required: Tune Up Kit
NOTE
Always brush dirt and debris away from air cleaner area prior to
cleaning air filter.
1. Brush dirt off air cleaner area. Keep dirt away from engine and
air intake grid.
2. Remove air filter cover. Brush dirt from inside cover and away
from edges of air filter.
3. Check air filter seal for tight fit with air filter case.
4. Remove air filter from case. Use care to prevent dirt and debris
from falling into air filter case.
5. Inspect filter element and seal. Replace filter if any of these prob-
lems are present:
•Air filter seal does not fit tightly against case
•Air filter seal is distorted, worn, or damaged
•Air filter element has holes or other damage
•Air filter element is saturated with dirt
•Air filter element is soaked with fuel mix
6. If air filter is in good condition and can be cleaned and reused,
lightly brush debris from air filter element, or blow filter element
clean using low pressure (40 psi or less) compressed air directed
at inside of filter.
IMPORTANT
When using compressed air, always direct air stream at inside sur-
face of filter so dust and debris will be blown out of filter. Keep air
nozzle 6 - 8 inches away from filter to prevent damage to filter.
7. Install air filter in case, and replace cover.
NOTICE
Actual replacement interval for air filter depends on operating con-
ditions. Operation in dustier applications requires more frequent
cleaning and replacement. Continued operation with a damaged
or excessively dirty filter will allow dirt and debris to enter engine,
and result in poor performance, rapid engine wear, and premature
engine failure.

FUEL FILTER
Level 1.
Parts required: Tune Up Kit
DANGER
Fuel is VERY flammable. Use extreme care when mixing, storing
or handling.
1. Use a clean rag to remove loose dirt from around fuel cap and
empty fuel tank.
2. Use the “fuel line hook” to pull the fuel line and filter from the
tank.
3. Remove the filter from the line and install the new filter.
NOTE
Federal EPA regulations require all model year 2012 and later gaso-
line powered engines produced for sale in the United States to be
equipped with a special low permeation fuel supply hose between
the carburetor and fuel tank. When servicing model year 2012 and
later equipment, only fuel supply hoses certified by EPA can be
used to replace the original equipment supply hose. Fines up to
$37,500 may be enforced for using an un-certified replacement part.
SPARK PLUG
Level 2.
Parts Required: Tune Up Kit
IMPORTANT
Use only NGK BPM-8Y spark plug (BPMR-8Y in Canada)
otherwise severe engine damage may occur.
1. Remove spark plug cover and spark plug, check for fouling, worn
and rounded center electrode.
2. Clean the plug or replace with a new one. DO NOT sand blast to
clean. Remaining sand will damage engine.
3. Adjust spark plug gap by bending outer electrode.
4. Tighten spark plug to 150-170 kgf • cm (130-150 in • lbf).
5. Install spark plug cover.
IMPORTANT
Always reinstall spark plug cover, otherwise engine cooling will
be greatly reduced, and engine failure will result.

COOLING SYSTEMS CLEANING
Level 2.
Parts Required: None, if you are careful.
IMPORTANT
To maintain proper engine operating temperatures, cooling air
mustpass freely through the cylinder fin area. This flow of air
carriescombustion 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.
Removal of cooling passage blockages or cleaning of cooling fins is
considered “Normal Maintenance.” Any failure attributed to lack of
maintenance is not warranted.
Cleaning Grill
1. Remove accumulated debris from intake grill between backpack
frame and blower housing.
Cleaning Cylinder Fins
1. Remove spark plug cover and spark plug.
2. Remove engine cover (five screws), pull cover away from engine,
and tie temporary knot in starter rope. Clean cylinder fins to allow
cooling air to pass freely.
IMPORTANT
Always reinstall spark plug cover, otherwise engine cooling will
be greatly reduced, and engine failure will result.
