Storing Your RV Generator Set
Proper storage is essential for preserving top generator set performance and reliability. If the generator set is not going to be exercised on a regular basis and not be used for more than 120 days, the generator set should be prepared for storage.
- If the generator set is a gasoline model, perform the following steps.
|Gasoline preservatives (stabilizers) are toxic. Follow the instructions on the container. Avoid skin contact. Wash hands with soap and water after using.|
- Fill the fuel tank with fresh fuel and add a fuel preservative (such as OnaFresh), following the instructions on the container label.
|If a preservative (stabilizer) is not added to the gasoline, the gasoline in the fuel system deteriorates causing fuel system corrosion, gum formation, and varnish-like deposits which can lead to hard starting and rough operation.|
- Run the generator set for about 30 minutes plus 2 minutes per foot of fuel line at approximately 1/2 rated power to fill the fuel lines with fresh fuel and preservative.
- Change the engine oil and attach a tag indicating the oil grade viscosity.
- Remove the air filter and restart the generator set. While the generator set is running, spray an engine fogger (such as OnaGard) into the carburetor, following the instructions on the container label.
|The engine fogger leaves a protective coat of oil on the internal surfaces of the engine.|
- Stop the generator set.
- Disconnect all appliances.
- Disconnect the battery cables, negative (–) cable first, from the starting battery and store the battery according to the battery manufacturer’s recommendations.
- Cap the exhaust tail pipe to keep out dirt, moisture, rodents, and other foreign materials.
- Close the fuel supply valve (if so equipped).
- Position the line circuit breaker to OFF.
|LPG leaks can lead to explosive accumulation in pits, sumps, or other below-grade locations. Comply will all local ordinances regarding the garaging of vehicles with LPG engine fuel systems.|
- If the generator set is an LPG model, check the local ordinances if the vehicle is going to be garaged. Generally, ordinances require that the LPG system be leak‐free, that the LPG container not be filled beyond specified limits, that the container shutoff valve be closed, and that the vehicle not be parked near sources of heat or ignition.
|Do not open the carburetor drain when the engine is hot. Close the drain immediately after draining. Failure to heed this warning can lead to fire resulting in severe personal injury or death.|
- If the generator set is a gasoline model, perform the following steps to drain the carburetor float bowl.
|Draining the float bowl prevents deposits of gum from clogging the tiny passages in the carburetor because the gasoline in the bowl evaporates during storage.|
- Let the engine cool down thoroughly.
- Place paper towels under the drain to absorb all of the drainage (less than 1/2 cup).
|Opening the carburetor drain when the engine is hot can lead to fire resulting in severe personal injury or death. Do not open the drain when the engine is hot. Close the drain immediately after draining.|
- Open the drain valve by turning counter-clockwise with a screwdriver.
- When draining is done, close the drain valve, turning clockwise with a screwdriver until just snug.
