Recommended original and replacement
bar and chain combinations
Following is a list of recommended cutting equipment for the Husqvama chain
saw models 340,345 and 350. The combinations of powerhead, bar and chain
have been investigated in accordance with the kickback and vibration
requirements of ANSI B 175.1 - 1991.
The guide bar nose radius is determined by either the maximum number of
teeth in the nose sprocket or the corresponding maximum nose radius of a
solid bar.
The following list is the chain saw manufacturers recommendations. There may
be other combinations available, which will also achieve kickback protection.
As we are listing the maximum guide bar nose radius, you may use a guide bar
with smaller nose radius than in our list. For guide bars of the same length, all
sprockebnose guide bars of the same pitch and having the same number of of
sprocket teeth may be considered to have equivalent kickback energy. A hard
nose bar having the same length and nose radius as a sprocket-nose bar may
be considered to have equivalent or less kickback energy than the sprocket-
nose bar.
Low kickback saw chain is a chain which has only met the kickback
performance requirements of ANSI B 175.1 safety requirements for gasoline-
powered chain saws when tested on the representative sample of chain saws
below 3.8 cu. in. specified in ANSI B 175.1. We recommend that you as
replacement use the listed chains or "Low kickback saw chains" which are
available at your dealer.
