Abstract:
A chainsaw sharpener mounted on and forward of the electric motor of a sharpener body (2) via a mounting portion (9) having a guide body (8) with an upper plate face (80) and wall faces (81a to 81e) which have a substantial X-shape as seen in plan view, and which are fit into and along an upper part of the saw chain in alignment with a sharpening angle of either a left or right cutter blade (31, 32) of a saw chain (30). Formed at a substantially central surface of the guide body (8) is an exposure portion made of openings (85, 86) which make it possible to watch, from above, the grinding tool (7) and a cutting edge of a cutter blade to be sharpened. A guide portion (87) presses, from above, the cutter blade to be sharpened so as to prevent the cutter blade from wobbling or tilting, and further to define an accurate cutting edge angle.
