SAW CHAIN MAINTENANCE

Following is a list of recommended cutting equipment for the Maruyama chain saw models MCV31T.
The combinations of power equipment, guide bar and saw chain have been tested and found to be in
accordance with the kickback and vibration requirements of ANSI B175.1–2000.
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 Maruyama's recommendations. There may be other combinations available, which will also
achieve kickback reduction.
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 sprocket-nose guide bars of the same pitch and having the same
number of sprocket teeth may be considered to have equivalent kickback energy.
When replacing the saw chain, identify the type of chain with the drive links mark.
The following combinations may be used on MCV31T.

Low-kickback saw chain is chain that has met the kickback performance requirements of ANSI B
175.1 - 2000(current revision of standard) (American National Standard for Power Tools-Gasoline-
Powered Chain Saws-Safety Requirements) when tested on the representative sample of chain saws
below 3.8 c.i.d. specified in ANSI B 175.1- 2000(current revision of standard).
