摘要： PROBLEM TO BE SOLVED: To provide a portable working machine capable of starting an engine easily by manual operation even when it is difficult to operate a starter device.
SOLUTION: A cut-off saw is constituted by providing the electric starter device 40 on one end side of a crank shaft 21 of the engine 2 and a manual operation type recoil starter 50 on the other end side. For this reason, if operation of the usually used starter device 40 becomes difficult due to insufficiency of charging obtained by a battery, the engine 2 can be easily started by using the recoil starter 50 to improve ease of use. Since a mechanism for winding up a plate spring 47 by manual operation is unnecessary for the starter device 40, a structure of the starter device 40 can be simplified.
