7.4 ENGINE WARNING SYSTEMS
7.4.1
Water in Fuel Light
(27 HP Daihatsu Diesel Only)
: Located on the console to the
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.
7.4.3
Warning Buzzer: Located behind the seat on the left hand side of the engine air
deflector. The buzzer is a warning signal for the following circumstances:
a) When the engine is not running and the ignition switch is turned to the ON
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.
b) When the engine is running and the buzzer emits a continuous beep, the
buzzer is warning the user that the engine is overheating. Perform the
following steps.
1. Disengage the mower blades, and idle down the engine.
2. Look at the temperature gauge to determine if temperature
continues to increase. If it does, turn the unit off and allow the
engine and engine components to cool.
3. Check the coolant level. If necessary fill with coolant as described
in Section 5.1.2.
4. Remove any debris on or around the radiator that may restrict airflow.
c) When the engine is running and the buzzer emits intermittent beeps, the
buzzer is warning the user that the engine oil pressure is low. Perform the
following steps.
1. Turn the unit off, allow the engine and engine components to cool.
2. Check the oil level and fill, if necessary, as described in section 5.1.1.
3. Check for oil leaking from engine. If the engine is leaking, see
Engine Service Dealer.
