Abstract

The chain saw includes a motor (2), a chain flange (3), a chain (6), a chain flange lock (5), and a drive toothwheel (4) on the motor axle secured to it by key locking (12) and driving the chain (6). The drive toothwheel (4) is noticeably wide in the direction of the axle in comparison to the width of the chain (6) and it has a ridge (7) in die centre higher than the teeth (8) manufactured from the same blank and dividing the drive toothwheel (4) into two, with an open tooth section (4.1, 4.2) at both sides, one of which is in use and the other in reserve.
