If conditioned air system is to be operated, open condenser air inlet panels (fig. 2-21) and condenser air
outlet doors (fig. 2-21). Make sure panels and doors are secured in the open position.
Access to the top of the power unit for opening the condenser air inlet panels is provided by
four folding steps (fig. 2-21) on the right rear corner of the enclosure.
Open the engine air inlet door (fig. 2-21) and secure in the open position with the two door braces (fig. 2-
Open the instrument panel access door (fig. 2-21) and secure in the up position with the door fastener (fig.
Open the circuit breaker panel access door (fig. 2-21) and the air temperature control panel access door.
Check all doors and panels not specifically opened in the above steps to insure that they are closed and
Open the fuel shutoff valve (fig. 2-21).
Starting. Refer to figure 2-22 and start the power unit.
Operators working in the area of equipment generating high frequency noises, especially if
such equipment is operating in a confined area, will be required to wear ear plugs,
supplemented by ear protectors. See your safety or medical officer for examination
requirements and federal stock number for ear plugs and ear protectors.
If starter does not disengage at approximately 35 percent governed speed during start
procedure, place master switch in STOP position. If power unit does not shut down,
disconnect battery cables from battery terminals to stop the power unit.
Preparation for Stopping.
Close hot and cold water valves on water inlet and outlet connection panel (fig. 2-21).
If possible, shut off external equipment powered by 60 Hz and 400 Hz electrical systems.
Stopping. Refer to figure 2-23 and stop the power unit.
After Operation Procedures. Unless power unit shutdown is only temporary, perform the following procedures
Shut off water supply to the power unit.
Shut off fuel supply to the power unit.
Close and secure condenser air inlet panels (fig. 2-21), condenser air outlet doors (fig. 2-21), engine inlet

2-16. Operation of Equipment
a. Operation to Deliver 60 Hz Electrical Power. Refer to figure 2-24 for operation of the 60 Hz electrical system.
In case of accident from electrical shock, shut down power unit at once. If power unit cannot
be shut down, free victim from live conductor with a board or any nonconductor. If victim is
unconscious, apply artificial respiration and obtain medical help.
