A generator is a device that converts mechanical power into electrical energy. The most common type of generators are called alternators, which use electromagnetic induction to generate electricity. When you buy a used generator, it’s important to make sure it’s in good working order and will be able to provide you with the electricity you need when your power goes out.
Know what you need
Before you start shopping for a used generator, make sure you know what size and type of generator you need. Don’t buy more than you need, as it will cost more than necessary. Also make sure the generator fits your budget.
Size
The first thing to consider is the type and size of generator you need. There are small portable generators designed for backup power in case of power outages, and larger stationary generators that can provide backup power when needed or be hooked up to your main house wiring so they run all the time.
The more expensive models can handle a variety of different kinds of loads, while the least expensive portable ones are limited in what they can power up.
Check the engine
Look at the engine closely and check that there are no signs of leaks or damage. Make sure the oil looks clean and fresh and there is no water in it. Also check that all belts are tight and secure with no cracks or fraying edges.
Look for other problems
Check for any signs of rust or corrosion on movable parts like handles, wheels and vents. Make sure there are no loose screws or bolts on any part of the machine such as fuel lines or electrical connections; this could indicate damage caused by misuse or poor maintenance over time.
Noise
Also consider how noisy it will be while running. If you’re planning on using it indoors or outdoors near a home, it’s important to find one that won’t wake up the neighbours or disturb other people living nearby.
Have it inspected by a professional mechanic
This will allow them to check the engine and make sure there are no issues with the internal workings of the machine.
Ask for service records from previous owners
This will help you determine if regular maintenance has been performed on the unit or if it has any known problems that need addressing before use.
Check for signs of wear on moving parts like belts and hoses; replace any damaged parts before using the machine again.
