Embodiment Construction

[0032] Figures 3 to 5 A miter saw is shown with a head 7 mounted pivotably above a workpiece support 8, which carries a saw blade 11 together with a blade guard 10 and as in particular Figure 5 The shown is equipped with a handle in order to pivot the saw blade 11 from the upper saw blade position / rest position into the lower saw blade position / working position and back.

[0033] The head 7 is hinged here on a support, not shown in more detail, which connects the head 7 to a frame, which is rotatable in the form of a turntable relative to two sections of the workpiece support 8, so that This enables chamfering to be produced.

[0034] When the saw blade 11 is lowered, that is to say when the handpiece 7 is pivoted downwards, the saw blade guard 10 which covers the saw blade 11 at least as far as possible in the rest position must be opened in order to be able to saw through the workpiece. When the saw blade 11 is raised again following the sawing process, that is to say when...

Abstract

The invention relates to a saw machine comprising a head for supporting a saw blade and a blade guard, a workpiece support and a frame, the head being between an upper saw blade position and an opposite lower saw blade position Pivotably received. In this case, the blade guard has a plurality of retractable and extendable segments mounted on the machine head, which protrude in the upper saw blade position as a saw blade guard and retract in the lower saw blade position. back, so that the blade is exposed for sawing, and there is a link connecting the bracket to the blade guard, which draws the segments of the blade guard together when the head is pressed down . A plurality of lamps are provided here, which are connected to a voltage source via switches. The invention is characterized in that above and / or below the link a switch is mounted on the bracket in such a way that said switch is actuated by the link when the handpiece is pressed down from the upper saw blade position, wherein when the handpiece is pressed from above When the saw blade position is pressed down, the plurality of lights are connected to a voltage source via a switch.

Description

technical field [0001] The invention relates to a saw machine, in particular a cut-off saw, a straight-cut saw, a miter saw or a straight-miter saw. Background technique [0002] It is known in panel saws to warn against a rotating pre-saw blade instead of simple markings by means of lights, see for example European patent application EP 2 210 722 A2. [0003] German patent application DE 10 2008 054 698 A1 discloses a signaling device equipped with LEDs on a circular saw, which signals whether a sensor is reacting sensitively, which detects whether the operator's body part has Get dangerously close to the saw blade. [0004] US patent application US 2014 / 0130643 A shows a circular saw in which there are different light sources, namely a transceiver on the one hand and a laser on the other hand, which are intended to detect whether a workpiece has reached the region of the saw blade. Independently of the two light sources, there is provided a microswitch which is mounted o...
