Recommended cutting equipment

Chainsaw model Zenoah GZ381 has been evaluated for
safety according to EN-ISO 11681-2 (Machinery for
forestry - Portable chainsaw safety requirements and
testing) and fulfills the safety requirements when
equipped with the below listed guide bar and saw chain
combination(s).

Equivalent sound pressure level, according to ISO 22868, is calculated as the time-weighted energy total for
different sound pressure levels under various working conditions. Typical statistical dispersion for equivalent
sound pressure level is a standard deviation of 1 dB (A).
4
Equivalent vibration level, according to ISO 22867, is calculated as the time-weighted energy total for vibration
levels under various working conditions. Reported data for equivalent vibration level has a typical statistical
dispersion (standard deviation) of 1 m/s

Kickback and guide bar nose radius

For sprocket nose bars the nose radius is defined by the
number of teeth (for example 10T). For solid guide bars
the nose radius is defined by the size of the nose radius.
For a given guide bar length, you may use a guide bar
with smaller nose radius than listed.
