The present disclosure relates to a hand-held power tool (1) comprising a rotatable work tool (2) with a center (16) and a circumference (17) and having a direction of rotation (19). The power tool (1) further comprises a blade guard arrangement (8) that is arranged to shield a variable part of the rotatable work tool (2) and comprises a blade guard (12) and a swiveling cover part (11, 11′, 11″) attached to the blade guard (12). In a first position, the swiveling cover part (11, 11′, 11″) is positioned such that a first arc (A) of a circle is covered, following the blade guard (12), and running an angular distance along the circumference (17) after the blade guard (12), in the direction of rotation (19). The cover part (11) is moveable between the first position and a second position where a cutting operation of the rotatable work tool (2) along the first arc (A) of a circle is allowed. The cover part (11, 11′, 11″) is biased towards the first position. The present disclosure also relates to blade guard arrangements.

A controller 50 is disposed to the front relative to a rotation shaft 11d of an electric motor 11 above a base 2, so as to be tilted in the up-to-down direction as it extends frontward.

A miter saw includes a base assembly and a saw unit pivotably coupled to the base assembly. The saw unit includes a motor for driving a saw blade about a rotational axis, a handle, a trigger coupled to the handle and moveable between a first position in which the motor is deactivated, and a second position in which the motor is activated to drive the saw blade, and a trigger lock pivotably coupled to the trigger for movement therewith to prevent movement of the trigger from the first position to the second position.

A handheld, hand-guided cutting-off machine (10), which includes a rotating cutting-off wheel, a supporting housing part (36), an output shaft, which is rotatably supported around an output axis (40), a drive motor, a transmission mechanism (19), which connects the drive motor to the output shaft, a flange and a safety guard (24), which covers the cutting-off wheel over a covering area. The cutting-off wheel is rotatably fixedly mounted on the output shaft with the aid of the flange and surrounded by the safety guard (24), which is pivotable around a pivot axis. The safety guard (24), the supporting housing part (36) and the transmission mechanism (19) have maximum distances from the output axis (40) over an outcut angle (), which are less than or equal to half the flange diameter of the flange.

A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.

The protective cooling cover comprises a hollow shell defining a generally semi-cylindrical cavity (15) that covers a portion of a cutting disc (2) at the top thereof and that is delimited by two lateral walls (11, 12) and a curved perimeter wall (13), a cooling device including a tube connected to a cooling liquid supply and to a cooling liquid projecting nozzle (31), and a fastening device for fixing the cooling liquid projecting nozzle (31) at different positions within the cavity (15) of the shell for projecting cooling liquid to different areas of the cutting disc, the fastening device including a plurality of first fasteners (17) connected to the periphery of the cavity, and a second fastener (32) connected to the cooling liquid projecting nozzle (31), the first and second fasteners (17, 32) providing a snap fit releasable connection.
