8.3. Infrequent use
•
Gasoline is extremely flammable and explosive under certain conditions.
•
Do not smoke or allow flames or sparks in the area.
•
During long-term storage, or infrequent use of your equipment, it is important to add a fuel stabilizer,
such as STA-BIL
®
Fuel Stabilizer, to help prevent fuel oxidation (breakdown) and the formation of gum
and varnish, and to inhibit corrosion in the fuel system.
1.
Be sure the storage area is free of excessive humidity and dust, and out of direct sunlight.
2.
It is best to keep the tank at least 95% full, as condensation will be less likely to occur in the fuel tank during storage
if the tank is full. Do not overfill the tank, as the fuel will need room to expand on hot days. Add an appropriate
amount of fuel stabilizer (per the instructions on the bottle) and run the generator for 5 minutes to ensure that any
fuel trapped in the system has the stabilizer in it. You may also opt to add the fuel stabilizer and run the unit until it is
out of fuel.
If you opt to drain the fuel, then continue on with the instructions below.
3.
To drain the gasoline from the fuel tank, turn the ignition switch to the “OFF” position.
4.
Siphon the fuel from the tank.
5.
Change the engine oil.
6.
Remove the spark plug and pour about a tablespoon of clean engine oil into the cylinder.
7.
Crank the engine several revolutions to distribute the oil and then reinstall the spark plug.
8.
Slowly pull the starter grip until resistance is felt. At this point, the piston is coming up on its compression stroke and
both the intake and exhaust valves are closed. Storing the engine in this position will help to protect it from internal
corrosion.
9.
Turn the remote switch to the “OFF” position to prevent unwanted, unintentional cranking and excessive battery
drain.
10.
Once a month, recharge the battery.
8.4. Exercising the Generator
It is essential that the generator be exercised on a regular basis. This will prevent the accumulation of varnish or sludge
in the fuel system; remove moisture from the generator windings and help keep the battery properly charged. Additionally
the engine seals and moving components will be lubricated. Exercise the generator by running it with at least a 1/2 load
(1800W) for 15 minutes per month. Gasoline fuel treatments (such as STA-BIL
®
) to prevent contamination of your fuel
supply are available from your dealer.
• Fuel varnishing necessitating replacement of the fuel injector is not a warrantable failure.
