    • Provided is an apparatus for lifting a retractable lower safety-guard on a circular saw. In one representative implementation, an actuator is attached to the circular saw and an elongated arm is coupled to the actuator such that operating the actuator causes the elongated arm to lift. In addition, an engagement element is attached to the retractable lower safety-guard of the circular saw. When lifted, the elongated arm engages the engagement element, thereby retracting the retractable lower safety-guard of the circular saw. Preferably, the actuator is configured, and is located sufficiently close to a power switch for the circular saw, so that the actuator can be operated simultaneously with the power switch using a single hand. Also provided are retrofitting techniques for attaching such a device to an existing circular saw.

    • The invention relates to a cutting-off apparatus, especially a circular saw, comprising two parallel circular disc-shaped, coaxially contra-rotating cutting-off elements (1, 2), especially circular saw blades, and a protective hood (3). In order to improve manual guidance and accident-free operation and positioning, the protective hood (3) can be moved in relation to the cutting-off elements (1, 2) and is loaded by a spring (4). The protective hood covers at least totally the cutting-off elements (1, 2) when it is placed in an inoperative position. When the protective hood (3) is supported on a workpiece that is to be cut-off or on a working surface, the cutting-off elements (1, 2) are moved (A, B, C) by the tension of the spring (4) into working position, in which the cutting-off elements (1, 2) partially come out from the protective hood (3) through an outlet (6).

    • A hand-held circular saw for a process for making plunge cuts with a saw a blade (10) protected by a casing (3), a pivoting safety guard (2) and an especially spring-loaded kerf guide, having sawteeth (11), with at least one hand-grip (5), with a cutting depth adjustment limited by a top and a bottom dead centre and a base plate (17), whereby at top dead centre the sawteeth (11) are some 3 mm at the most above the bottom of the base plate (17), which can be guided particularly on a guide rail which can be laid upon a workpiece and can be pivoted about an axis parallel to the sight line in relation to the saw blade (10) to make oblique or bevel cuts, is designed in such a way that, at top dead centre of the cutting depth adjustment, the distance between the bottom sawteeth (11) and the base plate (17) is much greater than 3 mm, preferably over 10 mm, whereby spring devices (23) attempt to maintain this distance and plunge saw cuts can be made with the hand-held circular saw (1), advantageously without the special plunge saw previously needed for such sawing processes.
