right of the hour meter. An illuminated water in fuel light signals water in the
diesel fuel. Water should be drained from the fuel filter if the light is on.
IMPORTANT: Water or other contaminants in the fuel can severely damage fuel
pump and/or other engine components.
7.4.2 Glow Plug Light (27 HP Daihatsu Diesel Only): Located on the console to the
right of the ignition switch. The glow plug light comes on when the ignition switch
is turned to the ON position. The glow plug light indicates the glow plugs are
preheating the combustion chamber. Wait for the glow plug light to go out before
starting the engine.

position, the buzzer emits intermittent beeps. The intermittent beeps remind
the user that the switch is ON and the hourmeter is running. A switch left ON
could also drain the battery.

buzzer is warning the user that the engine is overheating. Perform the
