Engine Emergency Stop Switch
The switch (3) is used to stop the engine in emergencies.
(a) ON (emergency stop) position
If the switch is pressed when indicator lamp (L) is off, the
engine will make an emergency stop. When this happens, indi-
cator lamp (L) lights up green to indicate that the engine emer-
gency stop switch has been actuated.
(b) OFF (normal operation) position
When the engine emergency stop switch has been actuated
(when indicator lamp (L) is lighted up), if the head of the switch
is turned clockwise, the switch returns to the OFF position and
the emergency stop is cancelled. When this happens, indicator
lamp (L) goes out.

It is possible to judge the status (ON/OFF) of the engine emer-
gency stop switch by checking the condition of indicator lamp
(L).

gency stop) position
