Method and guide bar clamping arrangement related to a motor saw

A motor saw comprising a guide bar (21) guiding a saw chain (5), a drive motor unit (1), a fixed support plate (7a) fixed relative to the motor unit (1), and a clamping plate (7b) adapted for clamping an inner end area (2d) of the guide bar (21) facing the drive motor unit (1) to the fixed support plate (7a) using a clamping means (7c) connected to the clamping plate (7b),

• wherein the clamping plate (7b) is adapted to be released from the inner end area (2d) by loosening the clamping means (7c) and displacing clamping plate (7b) at right angles a distance (“e”) in a direction from the support plate (7a) at which distance (“e”) the clamping plate (7b) still is connected to the clamping means (7c), and
• wherein the end area (2d) and guide bar (21) are adapted to be displaced along a plane (“P”) of the guide bar and thereby disconnected from the motor saw, while the clamping plate (7a) remains connected to the clamping means (7c) wherein the fixed support plate (7a) fixed relative to the drive motor unit (1) is provided with two projections (7a1, 7a2), and each projection is adapted for cooperation with recesses (21a1, 21a2) provided in the inner end area (2d) of the guide bar (21), and wherein the clamping means comprises threading (7c′) situated between the projections.
