The connection of proportional control of the chain saw is intended for automatic proportional control of the chain saw when cutting and after cutting of the trunk during the production of products on the manipulation lines in forestry and wood-processing industry. The goal of the invention is to safeguard automatic proportional control of speed of the saw feed when cutting and after cutting on the basis of the instant counter pressure of the cutting portion, decrease time of cutting of thinner trunks and increase the ability to cut as an indicator of saw quality in the whole range of thickness of processed trunks. The innovation in the connection is, according to the image, the use of the pressure/voltage converter (1,2) when cutting and after cutting, selection block (3) of the pressure converter of the source (4) of reference voltage, comparator (5), electronic block (6) of the proportional distributor, connection of the superior control system (7) and proportional distributor (11) with the first and second coil (10, 9) and with the position reader (8) of the valve. The connection of the proportional control of the chain saw can be used on manipulation lines in forestry and wood-processing industry, as well as with stable and mobile facing machines in forestry.<IMAGE>
