Reduction of Vibration in Power Saws in Japan.
NIOSH 1977 Apr:209-217
The problem of chain saw induced Raynaud's disease in Japan is presented. Techniques for minimizing vibration and noise emanating from presently manufactured chain saws are discussed. A rotary engine type chain saw has been developed, production prototype units have been constructed, and tests are presently underway in forests in Japan. Performance specifications as well as vibration and noise abatement techniques are compared between the normal reciprocating engine chain saw and the new rotary design.
