SHC-2620 SAFETY ENGLISH Personal Condition and Safety Equipment Users of this product risk injury to themselves and others if the unit is used improperly and/or safety precautions are not followed. Proper clothing and safety gear must be worn when operating unit. 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.
SAFETY SHC-2620 • For additional safety, a full-face shield may be worn over safety glasses or goggles to provide protection from sharp branches or flying debris. Hand Protection Wear sturdy, no-slip, rubber work gloves to improve your grip on the handles. Gloves also provide protection against cuts and scratches, cold environments, and reduce the transmission of machine vibration to your hands. Hearing/Ear Protection ECHO recommends wearing hearing protection whenever unit is used.
SHC-2620 SAFETY Extended Operation / Extreme Conditions Prolonged exposure to cold and/or vibration may result in injury. Read and follow all safety and operation instructions to minimize risk of injury. Failure to follow instructions may result in painful wrist/hand/arm injuries. 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.
SAFETY SHC-2620 Repetitive Stress Injuries (RSI) 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.
