BREAK-IN PERIOD
1. The fi rst 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 3 or 4 panels).
3. Oil consumption is greater during break-in as
piston rings take time to seat.
4. Break-In Oil Changes: Change engine oil and
fi lter at 50 hours. Change oil and fi lter again at
100 hours (consult Lubricants section for oil recom-
mendation).
Operating Instructions:
Maintain at least a 75% load on your generator
set for the fi rst 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 fi ller
cap sealing surface when the engine is cold.
CAUTION: Use protective clothing and open the
fi ller 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 waffl ed 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.
3. Check the fuel tank level and open any fuel valves.
4. Marine Sets: close the sea-cock, check and clean the
sea strainer and reopen the sea-cock.
5. Marine Sets: place the battery switch in the ON posi-
tion.
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 bat-
tery charging regulator could be ruined.
STARTING FOR S-1, S-1B, S-3, AND S-4, SEE
PAGE 6 FOR S-7
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.
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.
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
three 20-second cranks, remove the impeller from the
raw water 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 immedi-
ately and re-install the impeller. Re-start the engine
and check the exhaust overboard outlet for gushes of
water.
OPERATING
1. Units with Series 3, Series 4, 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 water temperature gauge on Marine sets must be
below 200°F (94°C); on Industrial units, the water
temperature gauge must be below 225°F (107°C).
Check the A.C. voltage and frequency meters (Series 4
and 6 panels). If the gauges deviate from normal levels,
shut down the generator set and investigate.
2. Let the unit run unloaded for a 3 - 5 minute warm-up
period.
3. Add electrical load.
STOPPING
1. Remove electrical load from the generator set.
2. Run the engine for a 3 to 5 minute cool down period.
2. Move the Engine Control switch to the STOP posi-
tion momentarily.
3. Marine Sets: shut off the seacock, fuel valve, and
battery switch.
