Good maintenance of the generator is important and simple. These instructions are based on my use and care of three different Honda generators in the past approximately 25 years. It started with a small 400 W to 1 KW (EX 1000) to the current EU2000i.
Brief summary. a. High quality oil is inexpensive insurance for long life. Change the oil as recommended or more frequently. If the generator was stored for long periods (1 year or more), play it safe and change the oil before using. b.
Sunday mornings at 9 AM), synthetic oil should not be used on a brand new engine unless specifically recommended by the engine manufacturer. If you elect to use synthetic oil, run the engine with the Honda-recommended conventional oil to allow the engine components to ‘set’ before switching to the synthetic. I switched to synthetic (Mobil 1, 10W –...

Hints: Run the engine for several minutes to warm up the oil prior to draining it. Avoid tilting the engine forward while the crankcase is full in order to drain the old oil as shown in Figure 3 and the Owner’s Manual. This can be messy (been there, done that)! A better way is to first pump out most of the oil.
After cleaning rinse it thoroughly with warm water and allow it to fully dry and re-oil it with filter oil. Honda suggests using engine oil, but does not give details about the oil weight. My preference is to use special air filter oil. A good source: K &...

Spark Plug The spark plug is located under a small cover at the top of the generator. It may be necessary to use a flat screw driver (gently) to pry open this cover. It opens from the bottom. Figure 7. Spark plug cover Figure 8.
An improperly tightened plug or wrong plug may damage the engine. Make sure to follow the instructions in the Owner’s manual. The Honda recommended spark plus is NGK CR5HSB. Gap should be 0.024 – 0.026 inch. My search for an equivalent Champion spark plug did not find any.
Long-Term Storage Prior to a long period of non-use, it is essential to drain the fuel system as described in Short-Term Storage, above. In addition, you should fog the cylinders with fogging oil (if necessary regular oil can used as well) which provides a protective coating to the combustion cylinder and related parts to prevent corrosion.
Preparing to Use After Long-Term Storage Pour a small amount of gasoline into the tank, start the engine with a small load. While the engine is running, pour the manufacturer’s recommended dose of carburetor cleaner and run the engine until it is ‘nice and warm’. Drain the old oil and refill with fresh oil.
