Tips for Heavy Generator Use: How to Spot Service Needs

Nov 11, 2021 | Generators

“When it comes to generator maintenance, your eyes are the best line of defense,” advises Gary Odden, Product Manager of Generators at Kubota Engine America. Generators may require less active service than engines, but they require high surveillance.

When using Kubota generators heavily, they are bound to experience a general level of wear and tear. To save time, money and reduce risk factors in the long run, our service team recommends adhering to the following tips.


Perform maintenance on time

Depending on your generator model, particular services should be performed at key milestones of usage: 50, 100, 250, 500 hours, etc. Keep track of the hour meter to ensure parts are promptly replaced.

Not sure if your generator needs professional assistance? Tip: Pay close attention to the voltage meter. If it reads inconsistently instead of remaining steady, this is a key indicator that the generator needs service.


Monitor corrosion and weather impacts

To keep your generator running optimally, always stay alert to signs of deterioration.

The coastal areas of North America pose the highest risk for corrosion. If you are operating your generator in a humid climate with exposure to sea salt, pay special attention to signs of corrosion. In areas with heavy precipitation, it is also key to ensure moisture never enters the generator.

In colder climates, recommendations alter slightly. Read our blog about maintaining your generator in cold weather and preparing your generator for use after long storage for more details.


Always keep a fresh supply of fuel

Your generator should never run out of fuel. Keep a close eye on the fuel tank at all times, especially for generators powered by diesel engines. This will help avoid difficulty restarting the engine and save money in the long run.


Physically inspect the generator and its surroundings

Examining your generator helps it to avoid ingestion or hampering.

Follow these steps for a successful inspection:

  • Switch the power off.
  • Ensure your generator is properly grounded and absent of electrical issues – check all connections and components for any signs of damage or corrosion. Most importantly, examine the receptacles and terminals before connecting to them.
  • Check for loose bolts, trash buildup, oil or coolant leaks, and broken or worn-out parts.
  • All intake ports should be open and free of any blockages that could restrict airflow. When inspecting, make sure nothing has taken up residence inside your generator.
  • Look for any signs of corrosion on the battery leads. Performing a battery test will let you know if your generator has a proper charge.


Our service team always recommends referring to the operator’s manual for service intervals and other safety protocols specific to your generator model. If you have concerns or notice any signs of hazard, immediately shut down the generator and contact your authorized Kubota service dealer.
