Frequently asked questions

Generally speaking, the more regularly your generator is called into action, the more frequently it should be used, however, this isn’t always the case. Depending on how much your back up power source is used, you might want to consider having it serviced annually, although some prefer to opt for every 6 months (or every 400 hours, depending on which comes first). For a small one-off cost each year, you will can help to avoid any major problems further down the line.

Regardless of use, your generator should undergo regular maintenance and oil changes. Over time, additives can break down in the oil which may lead to reduced performance. Oil should be changed after every 50-60 hours of your generator being used to ensure years of reliability.

Your diesel generator may become faulty without you realising it, especially if it isn’t used for some time. It’s a wise idea to check that your generator is working every so often to avoid major problems cropping up at the worst possible moment. Annual servicing and maintenance will give you peace of mind that your backup generator will work when you need it to.

The cost of generator service and repairs can depend on the work involved, whether the generator is portable or standby and whether the set is a low end model or a high end model. More powerful generators will often require extra maintenance, as will sets that have undergone more usage throughout the year. It’s a wise idea to call for a quote before you book your annual generator service.

Well, that depends on the specifications of the engine manufacturer. Generally, high quality 30-weight detergent is acceptable for summer conditions; quality 10W-30 is acceptable for winter conditions, but be sure to refer to your engine manual for oil recommendations.

Removing the gasoline is always a good idea when you’re going to be storing your generator for a long period of time, especially if you plan on storing it inside. It’s never advisable to store combustible materials inside of your home, as the result can be very severe.

Like we mentioned above, it’s not a good idea to store gas in a generator. However, if you’re storing gas in a can for your generator, a fuel stabiliser is definitely a good idea. If you require additional information, we offer generator servicing to all of our clients.

We can do this for you as we offer generator servicing to all of our customers, but if you’d like to do it yourself, it’s important to know that regular generator servicing involves changing the oil. A good tip is to run your generator for a few minutes first, to get the engine warm as this will help the oil and other contaminants to drain easier. You will then need to place an oil catcher under the oil pan and remove the cap, replace the cap and change the oil filter. Now you can add the recommended oil and restart the generator, after running for a few minutes you should turn the generator off and check the oil level again. This is one of the most important services that you can perform on your generator, but we can perform it for you if you require professional generator servicing services.

This will vary a lot depending on your generator, its capacity, the size of its tank and the size of the load you are placing on it. We recommend checking with the manufacturer to learn more about your generator. If you think your generator is under-performing and you’d like a professional to take a look, bring it to us for generator servicing.
