Now that you have checked your oil level, it’s time to replace it. Replacing the oil in your generator is one of the most important steps in keeping your machine running smoothly and efficiently. It’s important to do this every three months or after every 50 hours of use – whichever comes first.

When you’re ready to replace the oil, start by draining the old oil from the engine. To do this, make sure your generator is on a flat surface so that all the oil can be easily drained out. Then remove the drain plug and allow the used oil to drain out into an approved container for proper disposal completely. Once all of the old oil has been removed, reinstall the drain plug and tighten it securely with a wrench.

Now it’s time to add new oil back into your generator’s engine. Be sure to use only high-grade motor oil that meets your generator manufacturer’s specifications for viscosity, type, and grade. Make sure to fill up with just enough engine oil as specified in your owner’s manual – usually about one quart per 25 horsepower rating – but don’t overfill!

Once you’ve added new oil to your machine, clean up any spills immediately with a rag or paper towel and dispose of them properly according to local regulations. With that done, you’re ready to move on to replacing the air filter!

Replacing The Air Filter

Replacing the air filter is an essential part of keeping your portable generator running smoothly. It’s important to check your generator’s air filter every time you use it, and replace it when necessary.

Here’s an easy guide to changing the air filter on your portable generator:
