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) ambi-
ent 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. Let the unit run unloaded for a three to fi ve
minute warm-up period.
3. Add electrical load.
STOPPING
1. Remove electrical load from the generator set.
2. Run the engine for a three to fi ve minute cool-
down period.
3. Move the Engine Control switch to the STOP
position until the engine stops completely.
4. Shut off seacock, fuel valve, and battery
switch.
STARTING
1. Hold the Shutdown Bypass switch in the ON
position for 10-20 seconds before starting.
NOTE: Holding the switch too long can burn
out the glow plugs.
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
20 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 20-
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 it off immediately and
reinstall the impeller.
Restart and check the exhaust
overboard outlet for gushes of water.
