The method comprises the steps of providing (120) an elongated core plate (5) extending along a plane, and, in said plane has a length (Lc) in the longitudinal direction (D), and a width (Wc) perpendicular to the longitudinal direction (D), comprising a pair of opposite long side edges (33) and at least one detachable element (31) that extends along at least one of the long side edges of the core plate. Arranging (140) a side plate (23a, 23b) on each side of the core plate (25), thereby forming a sandwiched structure and joining (160) of the plates (23a, 23b, 25) for formation of an elongated guide bar (5), wherein the at least one detachable element (31) remains attached to the core plate (25). The disclosure also relates to a guide bar (5) for a chainsaw (1).

Abstract: A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around which a chain is rotatable. The guide bar (120) includes a first side plate (200) and a second side plate (210) facing each other and extending away from the housing (110) to a nose of the guide bar (120), the first and second side plates (200 and 210) each including an inner sidewall (224 and 222) facing inwardly toward each other. Each of the inner sidewalls (224 and 222) includes a recessed portion (230) at which material of the inner sidewalls (224 and 222) has been removed.

Abstract: The present disclosure relates to a guide bar (1) for a chain saw (3) with a proximal section (7), a distal section (13), and an intermediate section (15) between the proxymal and distal sections. The periphery of the guide bar defines a saw chain guide for guiding saw chain links along a path (31) from an engagement location (27) one edge of the bar to a disengagement location on the other. The periphery of the guide bar, where the saw chain links are supported only by the guide bar periphery has a curvature which is free from abrupt changes or step-wise changes. This provides a guide bar (1) less subject to wear during use.

Abstract: A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around which a chain is rotatable. The guide bar (120) includes first and second side plates (200 and 210), a sprocket wheel (220), first and second shims (240 and 242), and first and second sealing members (244 and 245). The first and second side plates (200 and 210) each face other and extend away from a housing (110) to a nose. The sprocket wheel (220) is provided at the nose between the first and second side plates (200 and 210). The first and second shims (240 and 242) are disposed between the first and second side plates (200 and 210), respectively, and corresponding ones of first and second sides of the sprocket wheel (220). The first sealing member (244) is disposed between the first shim (240) and the first side of the sprocket wheel (220).

Abstract: A chainsaw (100) includes a power unit and a working assembly powered responsive to operation of the power unit. The working assembly includes a guide bar (120) around which a chain is rotatable. The guide bar (120) includes first and second side plates (200, 210) and a laminate core (260). The guide bar (120) is configured to deliver water through at least a portion of the guide bar (120). The first and second side plates (200, 210) each face other and extend away from a housing (110) to a nose. The laminate core (260) is disposed between the first side plate (200) and the second side plate (210). The laminate core (260) includes channels (270) for delivery of the water to nozzles (300, 310, 320) formed along a periphery of the guide bar (120). A glue layer (280) is provided to affix the laminate core (260) to the first side plate (200) and second side plate (210), respectively. The glue layer (280) forms the nozzles (300, 310, 320) in combination with the laminate core (260).

Abstract: The invention relates to a saw chain depth gauge filing template (1), comprising a first flat section (2) and a second flat section (3), wherein both sections (2, 3) are made from a single piece of flat metal, especially from sheet metal, wherein the first flat section (2) has a first bearing surface (4) for a cutter link edge (5) of a saw chain (6) to be filed, wherein the second flat section (3) has second bearing surfaces (7) for a drive link (8) of the saw chain (6), wherein the second surfaces (7) are established by an linear edge (9) in which at least two incisions (10, 11; 10, 11) are machined, wherein the second flat section (3) has at least one cutout (12, 12) for a part of the saw chain (6) to be sharpened by filing. Furthermore, the invention relates to a method for sharpening a saw chain by using such a saw chain depth gauge filing template. By the proposed concept filing of a saw chain becomes possible in a more precise way.
