PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING
DANGER
Pro Attachment SeriesTM users risk injury to themselves and others if the Pro Attachment SeriesTM unit is used
improperly and or safety precautions are not followed. Proper clothing and safety gear must be worn when operating
a Pro Attachment SeriesTM unit.
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 handles. 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.
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,
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 trimmer 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
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 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.
WARNING
DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can

COOLING SYSTEM
Level2.
Tools required: 25 or 50 mm (1 or 2 in.) medium bristle cleaning brush,
Cross-HeadScrewdriver,4mmHexWrench
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.
