SAFETYINSTRUCTIONS
PERSONAL CONDITION AND SAFETY EQUIPMENT
WARNING DANGER
Trimmer/Brush Cutter users risk injury to themselves and others if the trimmer/brush cutter is used improperly
or safety precautions are not followed. Proper clothing and safety gear must be worn when operating a
trimmer/brushcutter.
EXTENDED OPERATION/EXTREME CONDITIONS
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
recommended,becausethe minimumexposurewhich mighttriggerthe
ailmentisunknown.
• 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.
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 handle. Gloves also reduce the transmission of
machine vibration to your hands.
Hearing Protection
ECHOrecommendswearinghearingprotectionwhenever
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
arecooler.

6
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).AnextremeRSIconditionisCarpalTunnelSyndrome
(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 grasp-
ing, 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.
EQUIPMENT
WARNING DANGER

safety manual.
• Check unit for loose/missing nuts, bolts, and screws. Tighten and/or
replace as needed.
• Inspect fuel lines, tank, and area around carburetor for fuel leaks. DO
NOT operate unit if leaks are found.
• Inspect shield for damage and ensure that the cut-off knife issecurely
