PROBLEM TO BE SOLVED: To improve setting operability of setting information. SOLUTION: The setting information is stored by a rewritable volatile memory 19 with the operation of a button (b) in a state where a key switch 17 is switched to a power ON position ON. The setting information stored in the memory 19 is stored in a rewritable nonvolatile memory 20 when the switch 17 is switched to a power OFF position OFF. After the setting information is stored in this memory 20, the power source is turned off. When information is set with the operation of a button (b) in a state where the switch 17 is switched to the power ON position ON and the number of the revolution of an engine is zero, the setting information is stored in the memory 20 whenever the button (b) is operated. |
