    • A power compass saw (10) with a housing (12) that accommodates a lifting rod for the up and down movement of a longitudinal saw blade (27) attached thereto, the saw blade having a toothed side and a saw blade back (270), and with a guide roller (29) which supports the saw blade back (270) and has a central circumferential groove (290) into which the saw blade extends with its saw blade back (270) and is guided therein, whereby the sides of the circumferential groove (290) are tapered, the power compass saw functioning particularly precisely and efficiently due to the fact that the saw blade back (270) of the saw blade (27) is designed with a 7° conical configuration and/or taper on both sides, so that it tapers toward the saw blade back (270) and is capable of being supported in two dimensions in the circumferential groove (290), the groove sides (291) of which have a 5° taper.
    • 一种具有壳体(12)的动力罗盘(10),其容纳用于附接到其上的纵向锯片(27)的上下运动的提升杆,所述锯片具有齿形侧和锯片后端(270) ,并且具有支撑锯片刃(270)的导向辊(29),并且具有中心圆周槽(290),锯片用其锯片背面(270)延伸并被引导到其中,由此, 圆周凹槽(290)是锥形的,由于锯片(27)的锯片背面(270)被设计为具有7°圆锥形构造和/或锥形的事实,功率罗盘精确而有效地起作用 两侧,使得其朝向锯片背面(270)逐渐变细,并且能够在周向槽(290)中以两个维度支撑,其槽侧(291)具有5°的锥度。
