2.2 Prestart Checklist
To ensure continued satisfactory operation, perform the following checks or inspections before or at each startup, as designated,
and at the intervals specified in the service schedule. In addition, some checks require verification after the unit starts.
Air Cleaner. Check for a clean and installed air cleaner element to prevent unfiltered air from entering the engine.
Air Inlets. Check for clean and unobstructed air inlets.
Battery. Check for tight battery connections. Consult the battery manufacturer’s instructions regarding battery care and
maintenance.
Enclosure. Check that all enclosure panels and internal baffling are in place.
Exhaust System. Check for exhaust leaks and blockages. Check the muffler condition.
 Inspect the exhaust system components for cracks, leaks, and corrosion. Check for tight exhaust system connections.
 Check for corroded or broken metal parts and replace them as needed.
 Check that the exhaust outlet is unobstructed.
Oil Level. Check the oil level before starting the generator set and at the intervals given in the Scheduled Maintenance section.
Maintain the oil level at or near, not over, the full mark on the dipstick.
Operating Area. Check for obstructions that could block the flow of cooling air. Keep the air intake area clean. Do not leave
rags, tools, or debris on or near the generator set.
2.3 Exercising the Generator Set
Operate the generator set without load once each week or every 2 weeks for 20 minutes. For instructions to set the exerciser,
see the section titled: Setting the Exerciser.
2.4 Generator Set Operation
2.4.1 Local Starting and Stopping
Start: Press the RUN button to immediately start the generator set.
Stop: Press the OFF button. The engine stops.
Run the generator set with no load for at least 2 minutes to ensure adequate engine cooldown.
2.4.2 Remote Starting and Stopping
The generator set must be in automatic mode for remote operation. Press the AUTO button on the VSC controller.
A remote switch connected to terminals 3 and 4 can be used to start and stop the generator set. Close the switch to start and
run the generator set. Open the switch to stop the generator set.
Run the generator set with no load for at least 2 minutes to ensure adequate engine cooldown.
2.4.3 Engine Start Crank Cycle
The controller attempts to start the generator set three times (three crank cycles, 15 seconds crank and 15 seconds off). If the
generator set does not start in three attempts, the system shuts down on an overcrank fault. See the section titled: Faults.
Cranking 1, 2, and 3 are displayed during the crank cycle. Pressing the OFF button during the crank cycle stops the cranking.
No other buttons are acknowledged during the crank cycle.
