BEFORE STARTING
1. Check the water level by removing the
pressure cap from the expansion tank. 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 between high and
low marks 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
on the tank and at the secondary fuel filter.
4. Close the sea-cock, check and clean the sea strainer,
and re-open 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
alternator could be damaged.
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.
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 recom
-
mendation).
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.
