Chain lubrication system

The is equipped with a lubrication oil pump integrated with the feed out cylinder. The lubrication oil pump supplies oil via a piston operation to the saw chain during the entire feed out process. The lubrication oil pump is fed with oil from the oil tank (1), through the inlet check valve (2) and to a reservoir in the piston rod (3). When the saw bar (8) is fed out, the oil goes through the outlet check valve (4), via a hydraulic hose (5) to the swivel in the saw motor (6) and finally through the bar holder to the saw bar (8). The supply of oil is proportional, which means that the volume of oil supplied depends on how much the saw bar is fed out. By using different lubrication oil pumps, the amount of oil supplied to the saw bar can be varied depending on different lubrication requirements.
