PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING DANGER
Power Blower users risk injury to themselves and others if the power blower is used improperly or safety precautions
are not followed. Proper clothing and safety gear must be worn when operating a blower.

4
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 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.
• DONOTWEARSHORTS,
• DONOTWEARTIES,SCARVES,andJEWELRY.
Wear sturdy work shoes with nonskid soles:
• DONOTWEAROPENTOEDSHOES,
• DONOTOPERATEUNITBAREFOOTED.
Keep long hair away from engine and blower 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.
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 recom-
mended,because theminimum exposure,which mighttrigger theailment, 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 physi-
cian 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
riskfordeveloping a RepetitiveStress Injury (RSI). Anextreme RSI conditionis 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
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 pre-
vented.
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
animalspreventedfromcomingnearerthan 15 m (50 ft.)whilethe
unit is in use.
• Take wind conditions into account: avoid open doors and
windows.
• Do not point blower at people or animals.
• Review area to be cleared. Look for potential hazards such as
stones or metal objects.
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
duringand immediately after operation.

Level2.
Tools required: 25-50mm(1-2in.)mediumbristlebrush,3mmHex
Wrench, Cross Head Screwdriver.
Parts Required: None, if you are careful.
IMPORTANT
To maintain proper engine operating temperatures, cooling air must
pass freely through the cylinder fin area. This flow of air carries
combustion 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. Brush accumulated debris from crankcase intake grill above the
fueltank.

CARBURETORADJUSTMENT
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel
break-in before carburetor adjustments can be made. During the break-in
period your engine performance will increase and exhaust emissions will
stabilize. Idle speed can be adjusted as required.
High Altitude Adjustment
High altitude adjustment is not required for proper operation of this
engine.
Level2.
Tools required: Screwdriver,tachometer(EchoP/N99051130017)
Parts required: None.
NOTE
Every unit is run at the factory and the carburetor is set in compli-
ance with emission regulations. This carburetor does not have
acceleration and high speed adjustment needles.
IdleAdjustment
Before adjustment make sure that:
• Air filter is clean and properly installed.
• Spark arrestor screen is free of carbon.
• Blowerpipes are installed.
1. Start engine, run at idle for one minute.
2. Complete warm up by running at full throttle for 5 minutes,
operating choke twice to clear air from carburetor chambers.
3. Check idle speed and reset if necessary. If a tachometer is
available, idle speed screw (A) should be set to the specifications
found on Page 20 "Specifications" of this manual. Turn idle screw
(A) clockwise to increase idle speed; counter clockwise to
decrease idle speed.
4. Accelerate to full throttle for 2-3 seconds to clear excess fuel from
engine then return to idle. Accelerate to full throttle to check for
smooth transition from idle to full throttle. If engine stops or stalls
after full warm up return the unit to your authorized ECHO dealer
forrepair.
Cylinder Exhaust Port
Level3.
IMPORTANT
The cylinder exhaust port must be inspected and cleaned of excess
carbon every 3 months or 90 hours of operation in order to maintain
this engine within the emissions durability period. ECHO strongly
recommends that you return your unit to your ECHO dealer for this
importantmaintenanceservice.
