    • A sawing machine comprises a housing (14), an arm (3) pivotable relative to the housing about an axis (2), a member (4) arranged on the arm, intended for connection to a saw tool and rotatable about an axis spaced from the pivot axis of the arm and parallel thereto, means (19) for rotating the rotatable member, means (38) for pivoting the arm relative to the housing, and an element (53) arranged on the arm, intended for connection to a guard for the saw tool and rotatable for changing the position of the guard relative to the arm depending upon the pivoting position of the arm relative to the housing. A device for automatical rotation of the element (53) comprises a part (30) secured against rotation relative to the housing and located in the area of the pivot axis (2) of the arm as well as means (68) for mechanical force transmission from this part to the rotatable element (53).
    • 锯切机包括壳体(14),可相对于壳体围绕轴线(2)枢转的臂(3);布置在臂上的构件(4),其用于连接到锯工具并且可围绕轴线间隔开 从所述臂的枢转轴线并与其平行的装置(19),用于旋转所述可旋转构件的装置(19),用于相对于所述壳体枢转所述臂的装置(38)以及布置在所述臂上的用于连接到所述臂的装置 根据臂相对于壳体的枢转位置,锯齿工具的防护装置可旋转以改变防护件相对于臂的位置。 元件(53)的自动旋转装置包括一个相对于壳体抵抗旋转的部件(30),并且位于臂的枢转轴线(2)的区域中,以及用于机械力传递的装置(68) 从该部分到可旋转元件(53)。
