1. A working machine with a working unit configured to perform a work, comprising:
a battery;
a control unit; and
an operation unit configured to accept an operation of controlling an operating state of the working unit, the operation unit including a first operator and a second operator,
wherein the working unit is set in the operating state when a user operates the second operator while operating the first operator,
the control unit has, as operation modes,
a normal mode in which the working unit is operable based on power of the battery, and
a power saving mode in which the working unit is made inoperable by limiting some of functions of the control unit, as compared with the normal mode, and power consumption of the battery is suppressed, as compared with the normal mode,
the control unit further has a stop state in which all functions of the control unit are limited,
the control unit is set in the normal mode when the user operates the first operator, and is set in the power saving mode when the user releases the operation of the first operator, and
the control unit enters the stop state
in a case where, in the normal mode, a remaining amount of the battery becomes smaller than a reference value,
in a case where, in the normal mode, the user has not operated the second operator for a predetermined period in a state that the first operator is operated, or
in a case where, in the power saving mode, the remaining amount of the battery becomes smaller than the reference value.
