The fresh water cooling system is under pressure when the engine is running and hot. Any
time the manifold's pressure cap is removed while the engine is hot, ensure that the cap is
removed slowly and that your hands are protected from escaping hot coolant. Depress the
pressure cap slightly and rotate it counterclockwise until the resistance of the safety stops are
felt. Carefully release pressure from the cap and allow the system's pressure to bleed off. Once
again press the cap down, now more firmly to clear the safety stops, and rotate
it
counterclock-
wise to remove and lift the cap off the manifold. Always fill the system full before replacing
the cap. Check the plastic recovery tank's coolant level, and add coolant if needed.
NOTE: Coolant recovery tanks mounted above the manifold fill cap will drain into the manifold
when the pressure cap is removed. To prevent this, pinch off the clear plastic hose running
from the manifold to the plastic recovery tank.
4. Restart the generator. Check the AC output. Load the generator. (Check data tag for rating). During
generator break in (first 50 hours), avoid light loads. Vary the loads. Load the generator gradually.
Stopping the Generator
1. Remove all the AC load from the generator.
2. Allow the engine to run for 5 minutes to dissipate engine heat and stabilize temperature.
3. Depress the red STOP switch and hold it until the engine stops completely.
