NOTICE
Always disconnect a battery charger from its AC source before
disconnecting the battery cables. Failure to do so can result in voltage
spikes high enough to damage the DC control circuits of the generator set.
NOTICE
Ventilate the battery area before working on or near the battery. Wear
goggles. Stop the generator set and disconnect the battery charger before
disconnecting the battery cables using an insulated wrench. Disconnect the
negative (–) cable first and reconnect it last.
All maintenance tasks must be assessed for health and safety risks; the preventive
measures identified must be performed. An additional person is required for any
task where doing so significantly adds to the safety of the task.
The installation of a generator set can be designed for remote starting. When
troubleshooting a generator set that is shut down, make sure that the generator set
cannot be accidentally re-started. Refer to the Locking the Generator Set Out of
Service section.
4.2 Introduction
This section describes the operation of the generator set. The text should be read in
conjunction with the Control System section of this manual.
All indicators, control switches/buttons, and graphical display are located on the
face of the Operator Panel.
4.3 Maintenance
To ensure maximum performance and reliability from your generator set, it is
essential that certain components are inspected periodically and, where necessary,
maintenance procedures are carried out, as detailed in the Maintenance chapter.
4.4 Operating Recommendations
Running-In
Refer to the Maintenance section of this manual. Special "running-in" oils are not
recommended for new or rebuilt Cummins engines. Use the same type of oil during
"running-in" as is used in normal operation.
The engine should be run at varying loads during the first few hours of operation to
allow the components to "bed in." Avoid long periods of light load or full load running
particularly during the early life of the engine.
