When the main switch (7) is turned to the GLOW position, the terminal BAT is connected to the terminal ON and
AC. The glow plugs (17) become red-hot, and the preheat indicator lamp also lights on while preheating.
When the main switch
is then turned to the START position with the safety switches on, the terminal BAT is
connected to the terminals
GLOW and ST. Consequently, battery (10) current flows to the starter motor (9) and start
the engine.
The main switch automatically returns to the
ON position, the terminal BAT is connected only to the terminal
GLOW, thereby causing the starting circuit to
be opened, stopping the starter motor.
When the main switch turned from the
ON position to the OFF position, the fuel cut-off solenoid moves the fuel
injection pump control rack to the
"No Fuel Injection" position and stops the engine.
The BX25 tractor (with the OPC timer (18))equipped the operator presence control (OPC) system which
automatically stops the engine
in approximately one second when operator stands from the seat while shifting the PTO
clutch lever
and range gear shift lever
