Storage
If you will not be using the generator set for a significant amount of time (3 months or longer) you
should store the generator to prevent any problems that could arise from sitting idle. Please
follow this procedure prior to storing the unit. This will help to ensure that the generator will start
and provide good service when it is removed from storage.
1. Remove fuel filler cap.
2. Use a siphon pump to remove all fuel from fuel tank.
3. Install fuel filler cap.
4. Start the generator set and allow it to run out of fuel.
5. Place the Engine Switch in “Stop” position. This closes the fuel valve.
6. Drain the used oil from the engine’s crankcase and refill it with clean oil.
7. Remove the spark plug and pour 1 oz. of clean engine oil into the cylinder. Put a rag
over the spark plug port and turn the engine over approximately 5 times to distribute
the oil in the cylinder.
8. Install the spark plug but do not connect the plug wire. This will help prevent accidental
or unauthorized starting.
9. Provide maintenance to the engine and generator set as described in this section.
10. Inspect bolts and nuts for tightness. Vibration can cause nuts or bolts to loosen.
11. Inspect the recoil starting rope for any damage and replace it if necessary.
12. Cover any bare metal spots with paint or another type of rust preventative.
WARNING: Never store an engine with fuel in its tank indoors or in an enclosed, poorly ventilated area
where gasoline fumes could reach an ignition source and cause an explosion.
