Abstract: The present invention refers to a motor saw arrangement comprising a support plate attached to the motor saw chassis or motor saw motor, a detachable clamping plate and a detachable guide bar arranged between the support plate and the clamping plate. The support plate is provided with two first recesses and at least one threaded hole, while the clamping plate is provided with two protrusions adapted to fit inside the respective two first recesses when the clamping plates is attached to the support plate and the protrusions each have a height that exceeds a corresponding height of the guide bar. The guide bar is provided with two keyhole-shaped slots and with a longitudinal slit between the two keyhole-shaped slots and the support plate is further provided with an alignment means. The invention further relates to a method to remove and/or replace a saw chain from a guide bar and to a guide bar intended and adapted for the motor saw arrangement described herein.

Abstract: Method and an arrangement within a motor saw, having a guide bar, a drive motor unit including with its chassis a drive motor, whose rotatable shaft supports a drive disc, around which a portion of an endless saw chain runs, the saw chain also being adapted with its remaining portions to run along and form the guide bar arrangement with its guide bar and along tracks allotted to side edges directed away from each other. An anchored support plate, a displaceable clamping plate and with an interrelated arrangement in an inactivated position, the end area of the guide bar within a first mode displaces the end area in a direction perpendicular from the plane and from the support plate, and within a second mode displacing the end area and its guide bar in a direction along the plane allotted to the guide bar and out of the inactivated interrelated arrangement.
