Renting a portable petrol generator comes with more than just picking it up and plugging it in. If you want it to work smoothly and avoid problems, you will need to keep an eye on some basic upkeep. Whether you’re powering tools on-site, lighting up an event, or just bracing for a power outage, here is what really matters when it comes to keeping that generator running right.

• Check Fuel and Oil Often
  

  Before every use, pop the hood—so to speak—and take a look at the oil and petrol levels. If the oil runs too low, the generator can overheat or stop working altogether. Some models shut down on their own if oil is low, which is a helpful safety feature. Still, better to stay ahead of it.

• Clean the Air Filter
  

  Generators suck in air to keep things running, but if the filter’s dirty, airflow drops. That forces the engine to work harder and use more fuel. Dusty job site? You will want to clean or swap the filter more often.

• Keep Tabs on the Spark Plug
  

  If the generator’s being a pain to start or seems sluggish, check the spark plug. A buildup of gunk can mess with the ignition. Replacing it is simple and can make a big difference in how well the engine runs.

• Ventilate It Properly
  

  Petrol generators produce carbon monoxide, which is dangerous in enclosed areas. Always run it outdoors or in a well-aired spot. Keep it away from windows or vents where exhaust might creep back inside.

• Avoid Overloading It
  

  Every generator has a limit for how much it can power. Pushing it too hard too often can burn it out quicker. Know the wattage of what you are plugging in and stay within the safe range.

• Check Fuel Lines for Leaks
  

  Leaking fuel is not just wasteful—it is risky. Look over hoses, caps, and connections for drips or cracks. Smell gas when there should not be any? Stop using the unit and let the rental company know.

• Stick to the Maintenance Schedule
  

  Most rental services offer upkeep as part of the deal. Find out when it’s due and don’t skip it. A pro can catch stuff that is easy to miss and keep the generator in better shape long-term.

• Store It Right
  

  Not using it for a while? Drain leftover fuel if advised, keep it covered, and store it somewhere dry and cool. Dampness and dust are not your friends here—they will mess with performance later.
