Why a Generator Service and Maintenance Contract is Important

Having a generator without a service and maintenance plan simply isn’t enough. Generators need regular maintenance to ensure they are in good health with oil and filter changes.

You would not leave your car on the drive for months at a time without turning the engine over and the same applies to your standby generator.

When called upon a generator needs to start first time. Therefore, starter battery maintenance is key to make sure this happens. Oil and fuel filters need to be changed regularly, and as with any engine, oil and coolant need topping up and changing every year.

A professionally maintained diesel generator working in harmony with your uninterruptible power supply will provide the ultimate back-up for your mission critical systems.
