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. 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 unit 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 (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. 
Some believe that prolonged exposure to vibration may contribute to CTS. 
CTS can cause severe pain for months or even years.
