Chainsaw model Zenoah GZ4350 has been evaluated
for safety according to (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).
Low kickback saw chain
A saw chain that is designated as Low kickback saw
chain, meets the low kickback requirement specified in
ANSI B175.1-2012.
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.

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
