PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING
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 youare 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 sensa-
tions followed by loss of color and numbness in the fingers. The following precautions are strongly recommended
becausethe 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.

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
riskfordevelopingaRepetitiveStressInjury(RSI).AnextremeRSIconditionisCarpal 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 prevented.
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
animalspreventedfromcomingnearerthan15m(50ft.)whilethe
unit is in use.
• Take wind conditions into account: avoid open doors and windows.
• Do not point blower at people or animals.
Keep a Firm Grip
• Hold the stick handle with thumb and fingers encircling the handle.
Keep a Solid Stance
• Maintain footing and balance at all times. Do not stand on slippery,

IMPORTANT
Carbon deposits in muffler will cause a drop in engine output and
overheating. Spark arrestor screen must be checked periodically.
1. Remove muffler cover, spark arrestor cover, gaskets, and spark
arrestor screen from muffler. Replace screen if plugged with
carbon deposits.
NOTE
When cleaning carbon deposit, be careful not to damage the
catalytic body.
2. Install muffler cover, spark arrestor cover, spark arrestor screen,
and gaskets.
3. Tighten all screws securely.
COOLING SYSTEMS
Level2.
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
• Brushaccumulateddebrisfromintakegrill.

CARBURETOR ADJUSTMENT
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 Operation
This engine has been factory adjusted to maintain satisfactory starting,
emission, and durability performance up to 1,100 feet above sea level
(ASL)(96.0kPa).Tomaintainproper engine operation and emission
compliance above 1,100 feet ASL the carburetor may need to be
adjusted by an authorized ECHO service dealer.
