7 Tips for Commercial Generator Maintenance

Commercial generators are essential for large businesses as even with a small power breakdown, they can suffer a loss worth millions of dollars. But by investing in a generator, you can prevent loss where every minute counts. They can immediately supply power when there is a power breakdown.

But simply installing a commercial generator is not enough. You have to make sure that you maintain it regularly so that it last longer without breaking down. Without further ado, let’s check out the seven best tips for commercial generator maintenance.

Cover Your Generator

Commercial generators are kept outside in the open; they become susceptible to damage by environmental factors such as rain and storms. Constant exposure to the ever-changing weather conditions can increase the wear and tear of your generator significantly. To protect it, you should cover your generator.

For permanent generators, consider installing covers made of hard-shell. This will protect them from snow, rain, or hail. For portable generators, you should install a fitted cover that will keep your generator in place if there are any strong winds.

Filter Cleaning

Every commercial generator has filters that collect debris and dust the more they are used. Make sure you clean the filters whenever possible. This is one of the most effective tips for commercial generator maintenance.

If the filters are extremely dirty, you should consider replacing them instead of cleaning them.

Oil Changing

Like cars, your generator has movable components, and you need to oil them to prevent the grinding of parts against one another.

Typically, your generator can run safely for 500 hours before you need to change the oil. If your generator requires oil changing frequently, it might be because of some technical issue. Be sure to get it checked by a professional.

Fuel Change

Fuel affects the efficiency of your generator. Unclean fuel can hinder the performance of your generator. It might consume more fuel or not run as efficiently. To avoid this from happening, you should change the fuel regularly.

Clean fuel will help your generator run efficiently without breakdowns, and you won’t feel the need to get your generator repaired.


The batteries are an essential part of your commercial generator. Without functioning batteries, your generator would be useless. For commercial generator maintenance, you should always check the batteries for any loose connections.

It’s not uncommon for the batteries to have a loose connection; they can easily be fixed. But loose connections can cause the terminals to corrode. Corrosion can damage your generator to a greater extent, and you might have to replace the batteries completely to prevent long-term damage.

Regular Usage

Generators are used to generate backup power in case of a power outage. But that doesn’t happen often. So, it’s possible that your generator just sits there without running, but a generator that hasn’t been in use for a long time can stop working entirely. To prevent that, you should run your generator for at least half an hour every month. This will keep your generator in working condition for a long time.

Belt Condition

The belts of a generator are always under pressure and stress even when they aren’t in use. Overstretched or torn belts need to be replaced immediately. Make sure that you inspect the condition of the belts every month as part of your commercial generator maintenance routine.

Commercial Generator Replacement

If your generator is breaking down frequently, even after repairs, you should consider getting it replaced. Investing in repairs will only waste money if your generator is not performing. For commercial generator replacement, you should consider hiring Assurance Power Systems. They deal in all kinds of commercial generator services, including generator replacement.
