FIELD: machine building.
SUBSTANCE: proposed system comprises stationary board. The latter makes a part of saw body to cover saw rear. Board end surface extends between board outer and inner surfaces. Board end surface features convex curvature. In saw operation, broken chain thrusts forward and outward. End surface hardness and large radius of curvature allows broken chain section to slide unobstructed around end surface toward inner surface. End surface makes cylinder part, for example, length or rod or tube rigidly secured to said board. End surface features radius approximating to 2.5 cm. End surface features hardness making, at least, 400 HB. Board outer surface features hardness making, at least, 400 HB. Board comprises band-type part to catch broken chain than extends all along said board.
EFFECT: reduced danger of chain discharge from saw band rear.
