In order toreduce the risk of whitefinger diseaseand carpal tunnel syndrome, pleasenote the following: Many Stihl models are availablewith an anti-vibration ( AV ) systemdesigned to reduce the transmissionof vibrations created by the engineand cutting attachment to theoperator s hands.

Heated handles, which areavailable on most Stihl power-heads, are recommended for coldweather use. Keep the saw Chain sharp and the saw, including the AV system, wellmaintained. A dull Chain will in-crease cutting time, and pressing adull Chain through wood will in-crease the vibrations transmitted toyour hands. A saw with loose com-ponents or with damaged or wornAV buffers will also tend to havehigher vibration levels. Maintain a firm grip at all times, butdo not squeeze the handles withconstant, excessive frequent the above mentioned precautions donot guarantee that you will not sustainwhitefinger disease or carpal tunnelsyndrome.
