Personal injury or death can result from high voltage.When power generation equipment must be in operation to make tests and/or adjustments, high voltage and current are present.Improper test equipment can fail and present a high voltage shock hazard to its user.Make sure the testing equipment is designed for and correctly operated for high voltage and current tests being made.
The engine shutdown override switch is located in the electrical box for the controller. The automatic shutdown system may be disabled if the unit is used in emergency situations. When the generator set is in this mode any fault will give an indication but the fault will not stop the engine.Turn the latch for the cover on the electrical box in order to open the electrical box and access the override switch.Fuel System-Prime
If air enters the fuel system, the air must be purged from the fuel system before the engine can be started. Air can enter the fuel system when the following events occur:
The fuel tank is empty or the fuel tank has been partially drained.
The low pressure fuel lines are disconnected.
A leak exists in the low pressure fuel system.
The fuel filter is replaced.
A new injection pump is installed.Use the following procedure in order to remove air from the fuel system:
Illustration 86 g01231641
Hold the toggle switch (1) in the ON position for 3 minutes to prime the system. Note: Damage to the fuel injection pump, to the battery, and to the starter motor can occur if the starter motor is used excessively to purge the air from the fuel system.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.
The engine is now ready to start.Cooling System

(12) Keel cooler for aftercoolerDuring engine operation, water pump (9) draws engine coolant from keel cooler (11). The water pump creates coolant flow through the system. The water pump is installed on the front of the timing case. The water pump is gear-driven by the fuel injection pump gear.Water pump (9) forces the coolant through a passage in the front of the timing case to the water jacket in the top left side of the cylinder block. One-third of the coolant flows around the element of oil cooler (8) to the rear of the cylinder block. Two-thirds of the coolant is used in order to cool the cylinder block. The coolant continues to the rear of the cylinder block and the coolant is diverted to the following locations:
Exhaust manifold (5)
