Saw blade arrangement (100) for a chainsaw, comprising a chassis (103); a saw blade (110) having a chain guide (116) for a chain (101); and a nose part (130) having a chain sprocket (150). The nose part (130) comprises a first outer plate (131) and a second outer plate (135). The saw blade (110) comprises a central plate (139), being arranged between the first outer plate (131) and the second outer plate (135). The saw blade (110) comprises a first fastening flange (123) and a second fastening flange (125). The first outer plate (131) has a first socket (134) for the first fastening flange (123) and the second outer plate (135) has a second socket (138) for the second fastening flange (125). The first fastening flange (123) and the second fastening flange (125) have shapes that do not align as viewed along the width (W) direction. The invention also relates to methods for manufacturing and using such saw blade ar- rangements.

Abstract
Saw blade arrangement (100) for a chainsaw, comprising a chassis (103); a saw blade (110) having a chain guide (116) for a chain (101); a nose part (130) having a chain sprocket (150); and a lubricant provision device (104), arranged to provide a lubricant to the chain (101). The saw blade (110) comprises a lubricant supply channel (121,122) running lengthwise (L) along said chain guide (116) from the chassis (103) to the nose part (130). The saw blade (110) further comprises a lubricant distribution channel (151) arranged to provide lubricant from the lubricant supply channel (121,122) to a chain (101) mounted on the saw blade (110). The lubricant distribution channel (151) is arranged to provide the lubricant to an up- stream lubrication point (154) on the nose part (130) before the chain (101) arrives at the chain sprocket (150). The invention also relates to methods for manufacturing and using such saw blade arrangements.

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.

Abstract
The present invention concerns a method and an arrangement within a motor saw, in the form of a motor saw arrangement ("A") having a guide bar arrangement (2) adapted to a drive motor unit (1) of said motor saw, with said drive motor unit (1) comprising with its chassis (1a) a drive motor (3), the rotatable shaft (3a) thereof is adapted to support a drive disc (4), such as a toothwheel (4a) shaped around the periphery (4") thereof, around which a portion (5a) of an endless saw chain (5) is adapted to run, said saw chain (5) also being adapted with its remaining portions to run along and to form said guide bar arrangement (2) with its guide bar (21) and along tracks (2a', 2b') allotted to side edges directed away from each other. The invention indicates the use of an anchored support plate (7a) and a displaceable clamping plate (7b) and with an interrelated arrangement (71) in an inactivated position the end area (2d) of said guide bar (21) within a first mode of motion is displacing the end area (2d) in a direction at right angles from said plane ("P") and at right angles from the support plate (7a) and within a second mode of motion displacing said end area (2d) and its guide bar (21) in a direction along said plane ("P") allotted to the guide bar and out of the inactivated interrelated arrangement (71).
