Check for corrosion at all wiring connections. Even minor corrosion may
cause a faulty connection. Clean connector terminals thoroughly with
electrical contact cleaner; apply dielectric grease and reconnect.

NOTE: When disconnecting electrical connectors DO NOT pull on the
wires to separate the connectors.

NOTE: After carefully checking the above steps, attempt to start the
engine. If it does not start, contact your authorized Exmark service dealer.

IMPORTANT: It is essential that all operator safety mechanisms be

connected and in proper operating condition prior to mower use.

When a problem occurs, do not overlook the simple causes. For example,
starting problems could be caused by an empty fuel tank.

The following table lists some of the common causes of trouble. Do not attempt
to service or replace major items or any items that call for special timing of
adjustment procedures (such as valves, governor, etc.). Have this work done by
your Engine Service Dealer.

7.4 ENGINE WARNING SYSTEMS

7.4.1

Water in Fuel Light: Located on the right fuel tank. 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: Located on the right fuel tank. 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 behind the

engine access panel. 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.
