It works on the principle of an L-shaped pipe section. The cylinder is a long pipe with a crank on one end, which is turned around by the operator, while the other end has the piston at its bottom. The piston is connected to the saw by an L-shaped pipe section. As the piston moves, the saw blade attached to the end of the pipe section moves with it. These cutting saws can be used to cut trees, branches, logs, and other trees.
