動される。On the other hand, the starting circuit 2 includes a starting control circuit which is connected to the starting motor 16 via the main switch 4, the starter switch 5, and the starting motor 16.
After sitting on the seat 9, power is supplied to the starting motor 16 by turning on the main switch 4 and the starter switch 15.
The motor 16 is energized, the drive power supply circuit is closed, and the motor 16 is driven.
以上のような構成により、エンジンＥの始動に際し操縦

る。By maintaining the state for more than a predetermined time, the glow controller 7 and glow plug 8 become red hot.After confirming that the glow controller 7 has transitioned to the proper red hot state, turning on the starter switch 15 starts the operation. The driving motor 16 is driven, and the engine E is started.
このようにエン・ジンＥが始動されその回転数が上昇す

に達した時点で常閉グロースイッチ６が聞取され、グロ
ープラグ８への給電が伴出される。When the engine E is started and its rotational speed increases, the lubricating oil pressure in the lubricating circuit H gradually increases, and when it reaches a normal value, the normally closed glow switch 6 is activated and the glow plug 8 is turned on. The power supply is accompanied.

ても良い。In addition, since preheating is not required when the temperature of the engine E is high, a changeover switch or a thermoswitch is provided in the preheating circuit 1, or the glow switch 5 is made lockable so that it is not interlocked with getting on and off the seat 9. It may be possible to select whether or not to use the glow plug 8 depending on the temperature.
尚後者の場合スタータスイッチ１５はグロースイッチ５
の動作に左右されない個所に結線する必要がある。In the latter case, the starter switch 15 is the glow switch 5.
It is necessary to connect the wires at a location that is not affected by the operation of the
