bREAK-IN PERIOd
1. The first 100 hours on a new or reconditioned
engine are critical to its life and performance.
2. Constantly check the engine temperature and oil
pressure gauges (sets with Series or panels).
. Oil consumption is greater during break-in as
piston rings take time to seat.
. Break-In Oil Changes: Change engine oil and
filter at 50 hours. Change oil and filter again at
100 hours, then at every 250 hours (consult
Lubricants section for oil recommendation).
Operating Instructions:
Maintain at least a 75% load on your generator
set for the first 100 hours. Vary the load will help
seat the rings.
bEfORE STARTINg
1. Check the water level by removing the pressure
cap from the expansion tank or radiator. In order to
give the cooling water an opportunity to expand, the
level should be about 1 in. (2.5 cm) below the filler
cap sealing surface when the engine is cold.
CAUTION: Use protective clothing and open
the filler cap carefully when the engine is warm
to prevent burns.
2. Check the oil level in the crankcase with the dip-
stick. The oil level must be in the waffled area on the
stick. Never allow the level to go below this area.
Always add the same viscosity of oil as is already in
the crankcase.
. Check the fuel tank level and open any fuel valves.
. Close the sea-cock, check and clean the sea strainer
and reopen the sea-cock.
5. Place the battery switch in the ON position.
NOTE: The battery switch must always be kept
ON while the engine is running. If the switch is
turned OFF while the engine is running, the
battery charging regulator could be ruined.
STARTINg
1. Hold the Shutdown Bypass-Preheat switch in the ON
position for 10 to 20 seconds before starting a cold
engine. Holding the switch too long can burn out the
glow plugs.
2. While holding the Shutdown Bypass-Preheat switch
in the ON position, push the Engine Control switch to
the START position.
. 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 first
attempt, be sure that it has stopped completely before
re-engaging.
NOTE: Excessive cranking of the starter on Marine
sets equipped with a water lift muffler can cause
engine damage. If the engine does not start after three
20-second cranks, remove the impeller from the raw
water pump. This will prevent the muffler from filling
with water and backfilling the exhaust line and engine.
Once the engine starts, shut it off immediately and re-
install the impeller. Re-start the engine and check the
exhaust overboard outlet for gushes of water.
OPERATINg
1. Units with Series , Series , and Series 7 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
coolant temperature gauge must be between 167°F and
1°F (75°C to 0°C). Check the A.C. voltage and
frequency meters (Series panel). If the gauges deviate
from normal levels, shut down the generator set and
investigate.
2. Let the unit run unloaded for a - 5 minute warm-up
period.
. Add electrical load.
STOPPINg
1. Remove electrical load from the generator set.
2. Run the engine for a to 5 minute cool down period.
. Move the Engine Control switch to the STOP
position momentarily.
. Shut off the seacock, fuel valve, and battery switch.
