OPERATOR'S MANUAL 5

SAFETY INSTRUCTIONS

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.

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 trimmer.

Hand Protection

Wear no-slip, heavy duty work gloves to improve your grip on the Trimmer/Brush Cutter 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.

•DO NOT WEAR SHORTS,

•DO NOT WEAR TIES, SCARVES, JEWELRY.

Wear sturdy work shoes with non-skid soles;

•DO NOT WEAR OPEN TOED SHOES,

•DO NOT OPERATE UNIT BAREFOOTED.

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 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.

EQUIPMENT

WARNING DANGER

Use only ECHO-approved attachments. Serious injury may result from the use of a non-approved attachment combination. ECHO, INC. will not be responsible for the failure of cutting devices, attachments, or accessories which have not been tested and approved by ECHO. Read and comply with all safety instructions listed in this manual and 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 is securely in place. Replace if either is damaged or missing.

•Check that the cutting attachment is firmly attached and in safe operating condition.

•Check that front loop handle and shoulder strap/ or shoulder/ waist harness are adjusted for safe, comfortable operation. See Assembly Section for proper adjustment.

•Keep exhaust area clear of flammable debris. Avoid contact during and immediately after operation.
