When the main switch (19) is turned to the PREHEAT position, the terminal BAT is connected to the terminals
GLOW and ON. The glow plugs (4) become red-hot, and the glow plug (preheat indicator) lamp also lights on while
preheating.
When the main switch (19) is then turned to the START position with the brake switch (20) on and PTO switch
(21) on, the terminal BAT is connected to the terminals START and ON. Consequently, battery current flows to the
starter motor (3) and start the engine.
The main switch (19) automatically returns to the ON position, the terminal BAT is connected only to the terminal
ON, thereby causing the starting circuit to be opened, stopping the starter motor (3).
When the main switch (19) turned from the ON position to the OFF position, the engine stop solenoid (5) moves
the fuel injection pump control rack to the "No Fuel Injection" position and stop the engine.
This machine equipped the operator presence control (OPC) system which automatically stops the engine when
operator stands from the seat while shifting the PTO lever.
With the PTO lever shifted to the "ENGAGE" position, the engine of this machine stops automatically when the
cover of the grass container opens, the grass container opens or dismounted.
