The work machine includes a power source and an additional function unit that realizes a predetermined additional function. The presentation unit presents a precaution related to the predetermined additional function. The activation control unit allows the power source to be activated after an operator confirms the precaution. ## Claims ### Claim 1 An activation system for a work machine including at least one actuator, a power source that supplies power to drive the at least one actuator, and an additional function unit that realizes a predetermined additional function, the activation system comprising: a power supply unit; and a computer including a processor configured to execute a program, the computer being configured to receive electric energy from the power supply unit and present a precaution related to the predetermined additional function when the power source is not activated, and determine whether or not the precaution is confirmed by an operator and allow the power source to be activated after it is determined that the precaution is confirmed, activation of the power source enabling the power source to be started. ### Claim 2 (depends on 1) The activation system for a work machine according to claim 1, wherein the additional function includes a function of detecting an obstacle in a periphery of the work machine using an imaging device provided in the work machine. ### Claim 3 (depends on 2) The activation system for a work machine according to claim 2, wherein the additional function includes a function of controlling an output of the at least one actuator driven by the power source based on a detection result of the obstacle. ### Claim 4 (depends on 1) The activation system for a work machine according to claim 1, wherein the work machine includes work equipment driven by the at least one actuator, and a work equipment control device configured to control the at least one actuator, and the computer is configured to allow the work equipment control device to be activated after the operator confirms the precaution. ### Claim 5 (depends on 1) The activation system for a work machine according to claim 1, wherein the work machine includes an operation lever usable to operate the at least one actuator, the computer is further configured to present an operation pattern of the operation lever, and the computer is configured to allow the power source to be activated after the operator confirms the precaution and the operation pattern. ### Claim 6 (depends on 1) The activation system for a work machine according to claim 1, wherein the computer is further configured to authenticate an operator who operates the work machine and present the precaution after the operator is authenticated. ### Claim 7 (depends on 1) The activation system for a work machine according to claim 1, wherein the work machine include a power source control unit configured to control the power source, and a starting switch usable to drive the power source control unit, and the computer is configured to operate the power source control unit in a case in which an operation of the starting switch is performed after the operator confirms the precaution, and not operate the power source control unit in a case in which an operation of the starting switch is performed before the operator confirms the precaution. ### Claim 8 (depends on 1) The activation system for a work machine according to claim 1, wherein the computer is configured to display the precaution on a monitor, and determine whether or not the precaution is confirmed by an input on the monitor. ### Claim 9 (depends on 1) The activation system for a work machine according to claim 1, wherein the computer is configured to output the precaution by voice, and determine whether or not the precaution is confirmed by voice recognition. ### Claim 10 (depends on 1) The activation system for a work machine according to claim 1, wherein the power source is an engine. ### Claim 11 An activation method for a work machine including at least one actuator, a power source that supplies power to drive the at least one actuator, and an additional function unit that realizes a predetermined additional function, the activation method comprising: presenting a precaution related to the additional function when the power source is not activated; determining whether or not the precaution is confirmed by an operator; and activating the power source after it is determined that the precaution is confirmed, the activating of the power source enabling the power source to be started. ### Claim 12 A work machine comprising: a power source; work equipment driven by the power source; an operation lever configured to operate the work equipment; an additional function unit configured to realize a predetermined additional function; a monitor configured to display a precaution related to the predetermined additional function when the power source is not activated; and an activation control unit configured to determine whether or not the precaution is conformed by an operator and allow the power source to be activated after it is determined that the precaution is confirmed, activation of the power source enabling the power source to be started, the monitor and the activation control unit receiving electric energy from a power supply unit that is different from the power source. ### Claim 13 (depends on 12) The work machine according to claim 12, wherein the monitor is further configured to present an operation pattern of the operation lever, and the activation control unit is configured to allow the power source to be activated after the operator confirms the precaution and the operation pattern. ### Claim 14 (depends on 12) The work machine according to claim 12, wherein the power source is an engine. ### Claim 15 An activation system for a work machine including at least one actuator, an operation lever usable to operate the at least one actuator, and a power source that supplies power to drive the at least one actuator, the activation system comprising: a power supply unit; and a computer including a processor configured to execute a program, the computer being configured to receive electric energy from the power supply unit and present a screen for confirming an operation setting content of the operation lever when the power source is not activated; and determine whether or not the operation setting content of the operation lever is confirmed by an operator and allow the power source to be activated after it is determined that the setting content of the operation lever is confirmed, activation of the power source enabling the power source to be started. ### Claim 16 (depends on 15) The activation system for a work machine according to claim 15, wherein the computer is configured to present the screen for confirming the operation setting content of the operation lever when the operator can be authenticated.
