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.
SAFETY PAS-2620 Eye Protection ◆ ◆ Eye protection that meets ANSI Z87.1 or CE requirements must be worn whenever you operate the unit. 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.
PAS-2620 SAFETY 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. 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.
SAFETY PAS-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.
