OPERATING
1. Units with Series 3 and Series 4 Control Panels:
check gauges often. Oil pressure must be above
15 PSI. The D.C. voltmeter should read between
11 and 15 volts at 80° F (25° C) ambient temperature.
The water temperature gauge must be below 200°
F (94° C). Check the A.C. voltage and frequency
meters (Series 4 panel). If the gauges deviate from
normal levels, shut down the generator set and
investigate.
2. Add electrical load.
STOPPING
1. Remove electrical load from the generator set.
2. Run the engine for a two to three minute cool-down
period.
3. Move the Engine Control switch to the STOP
position.
Operating Procedures
STARTING
1. Hold the Shutdown Bypass switch in the ON
position.
2. While holding the Shutdown Bypass switch in the
ON position, push the Engine Control switch to the
START position.
3. As soon as the engine starts, release both switches.
Do not crank the starter for more than 10 seconds
consecutively. If the engine fails to start with the
fi rst attempt, be sure that it has stopped completely
before re-engaging the starter.
NOTE: Excessive cranking of the starter on marine
sets equipped with a water lift muffl er can
cause engine damage. If the engine does not
start after 3 consecutive 10-second cranks,
remove the impeller from the seawater
pump. This will prevent the muffl er from
fi lling with water and backfi lling the exhaust
line and engine. Once the engine starts, shut
if off immediately and reinstall the impeller.
Restart and check the exhaust overboard
outlet for gushes of water.
