How to Maintain a Generator

Generators are used for the production of electricity. The majority of generators in operation today are either a portable or a standby type. Both of these types of generators are used on a temporary basis. Typically when the power goes out due to storms or other natural disasters. Just because these machines do not run regularly, they still need to be maintained. Proper maintenance will ensure efficient operation when the machine is put into service. Regardless of the frequency of use, a certain procedure should be followed.

Instructions

The Steps

1

Replace the sparkplug every two years or 100 hours of operation. Remove the old sparkplug in a counter clockwise direction using the correct sized wrench. Generally the wrench will come from the generators manufacturer. The sparkplug will be located on either the top or the side of the engine. A large rubber wire with a hood covers the sparkplug. This rubber hood will have to be removed to gain access to the metal nut on the sparkplug. Check the new sparkplug for the correct gap with the feeler gauge before placing the new one in the engine. The gap specifications will be shown on the sparkplugs container.

2

Change the oil in the generator every 200 hours or on a yearly basis. Moisture can migrate into the crankcase whenever the unit is in storage. Place the plastic bucket under the oil drain plug. This square metal plug is located on the lower portion of the engine. Tighten the crescent jaw around the square head and turn the wrench in a counterclockwise direction.

3

Remove the oil plug and allow the oil to drain into the bucket. Replace the plug and tighten with the crescent wrench. Clean up any spilled oil with the paper towels. Discard the towels and old oil according to local disposal regulations.

4

Pour the new oil into the oil fill plug. Follow the capacity rating as dictated by the manufacturer.

5

Add fresh gasoline to the fuel tank. Start the generator and allow to run in a well ventilated outdoor area. Run the unit for at least 15 minutes. Stop the engine and check the oil level to ensure proper capacity.

6

Add the proper amount of gasoline stabilizer into the fuel tank. There is a capacity chart listed on the side of the products container.

7

Test run the generator every 4 to 6 months to keep it conditioned.
