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.
The components of this machine generate an electromagnetic field 
during operation, which may interfere with some pacemakers. To 
reduce the risk of serious or fatal injury, persons with pacemakers 
should consult with their physician and the pacemaker 
manufacturer before operating this machine. In the absence of 
such information, ECHO does not recommend
 the use of this 
machine by anyone who has a pacemaker.
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.
