Japanese Patent JPH0378242
Kind Code:
B2
Abstract:
A chain saw is disclosed having a drive motor which drives the sprocket wheel of the saw chain via a transmission stage. The sprocket wheel rotates in the same direction as the drive shaft of the drive motor and drives the saw chain in such a manner that the portion thereof traversing the lower periphery of the cutter bar moves toward the housing of the chain saw. The saw chain is braked with a braking arrangement which develops a braking moment that causes the chain saw to develop a reaction moment that opposes the kickback moment occurring as a consequence of the kickback action. In this way, the angle through which the chain saw is deflected during kickback is reduced. In addition, a compact configuration of the motor housing of the chain saw is obtained wherein the braking arrangement is kept free of dirt and chips.
