Abstract
The invention is based on a saw, in particular a hand-guided saber saw, which has a drive unit (10) by way of which a tool (12), in particular a saw blade, can be driven, and with a tool guide mechanism (14), by way of which the tool (12) can be guided laterally by guide elements (16, 18). It is proposed that the tool guide mechanism (18) has a control motor (20), by way of which a spacing between the guide elements (16, 18) can be adjusted to a tool thickness.
Claims14
A saw, in particular a hand-guided saber saw, which has a drive unit (10) by way of which a tool (12), in particular a saw blade, can be driven, and with a tool guide mechanism (14), by way of which the tool (12) can be guided laterally by guide elements (16, 18), characterized in that the tool guide mechanism (18) has a control motor (20), by way of which a spacing between the guide elements (16, 18) can be adjusted to a tool thickness.
The saw of one of the foregoing claims, characterized in that the tool guide mechanism (14) has pivot arms (26, 28), connected via a joint (24), on which arms the guide elements (16, 18) are disposed.
The saw of one of the foregoing claims, characterized in that a control device (38) for opening the tool guide mechanism (14) is coupled at least operatively with a control device of a fastening mechanism of the tool (12).
The saw of one of the foregoing claims, characterized in that the tool guide mechanism (14) can be kept in an opening position via a retaining device after the removal of a tool (12).
The saw of one of the foregoing claims, characterized in that the guide elements of the tool guide mechanism are formed by roller bodies.
The saw of one of the foregoing claims, characterized in that the guide elements (16, 18) are held by detachable retaining elements (46, 48) and are replaceable.
