BREAK-IN PERIOD
1. The first 100 hours on a new or reconditioned
engine are critical to its life and performance.
2. Frequently 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
filter at 50 hours. Change oil and filter again at
100 hours (consult Lubricants section for oil
recommendation).
5. Retighten head bolts at 50 hours (see page 13).
Operating Instructions:
Maintain at least a 75% load on your generator
set for the first 100 hours. If this is not possible,
maintain no less than a 50% load to ensure proper
seating of the piston rings. Vary the load to 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
dipstick. 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.
3. Check the fuel tank level and open any fuel valves.
4. Marine Sets: close the sea-cock; check, clean, and
reassemble the sea strainer and reopen the sea-cock.
5. Marine Sets: place the battery switch in the ON
position.
6. 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. This step is not necessary if the
engine is already warm.
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 first attempt, be sure
that it has stopped completely before re-engaging.
6. 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 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 on Marine sets must be
below 200
°
F (94
°
C); on Industrial units the water
temperature gauge must be below 225
0
F (107
0
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 five minute
warm-up period.
3. Apply electrical load.
STOPPING
1. Remove electrical load from the generator set.
2. Run the engine for a 3 to 5 minute cool down period.
3. Hold the Engine Control switch to the STOP
position until the engine comes to a complete stop.
4. Marine Sets: shut off the seacock, fuel valve, and
battery switch.
