General

What is the difference between an air-cooled engine and a liquid-cooled engine for a generator?

Air-cooled generators use fans to flow air for cooling the engine. While liquid-cooled generators use splash lubrication systems for cooling the engine. Generally, liquid-cooled engines are used on larger wattage generators.

What is the difference between running watts and starting (surge) watts?

Running watts are the amount of power a generator produces continuously. On the other hand, starting watts are the amount of power a generator produces for short periods of time. Such as for starting up a connected appliance. Typically required for only a few seconds.

Can I connect a portable generator to my home?

Can I use the generator with an extension cord?

It is possible to use extension cords. While keeping in mind that a long cord will cause some drop in voltage. As a general rule, the voltage will drop by 2 – 3 volts for a 10-meter cord, 5 – 6 volts for a 20-meter cord, and 8 – 10 volts for the 30-meter cord. Therefore, using a very long cord is not recommended.

How does the fuel valve work?

A device that permits or stops the running of fuel to the engine. Before turning on the generator you should always keep the fuel valve open. Then it should be directly closed after turning off the generator.

 

Maintenance and Check Up

Is it good to refill oil for my portable generator?
