徴とするチエンソーの給油装置。 A grapple saw is attached to the tip of the work attachment of the work vehicle, and the chain saw of the grapple saw is rotatably driven by a hydraulic motor, and the pressure oil downstream of the hydraulic motor is applied to the saw feed cylinder to feed the chain saw into the cut. In the lubrication system that uses part of the pressure oil downstream of the hydraulic motor to lubricate the lubrication section of the chain saw, the downstream side of the hydraulic motor for driving the chain saw and the lubrication section of the chain saw are connected via a lubrication pump. A lubricating oil tank is provided which communicates with the oil supply pump, and the lubricating oil in the lubricant tank is normally supplied to the oil supply section of the chain saw through the casing of the oil supply pump, thereby controlling the downstream operation of the hydraulic motor. 1. An oil supply device for a chain saw, characterized in that when the pressure exceeds a predetermined pressure, a part of the pressure oil downstream of the hydraulic motor is supplied to the oil supply section of the chain saw via an oil supply pump.
