Gas Powered Weed Eaters Maintenance

how to maintain a gas powered string trimmerUnlike electric or cordless string trimmers, the gas powered tools require some additional maintenance and upkeep to function properly.

But don’t worry, there is only a handful of pretty easy tasks and the rewards are substantial – your trimmer would work better, last longer and will not break down.

Please bear in mind these steps are just general recommendations – for a complete and precise list check out the instruction manual of your product.

Let’s start with a quick video – you can find most of the "technical" tasks I’ll be talking about shown there so feel free to come back to it at any time and replay the actual part.

At the beginning of the season

  • Check the overall state of the unit – retighten any screws or nuts that are loose, check out for any broken parts (the protection guard for example) and take a look at the string whether it needs to be replaced.
  • Check the air filter and clean or replace if it’s dirty or damaged. A classical foam filter can be washed easily in warm soapy water.
  • Check the condition of the spark plug and replace it if needed – a bad one can cause the trimmer not to start.

Also, let the machine warm up for a few minutes, don’t start trimming immediately.

During the season

  • Clean the unit from dirt and debris frequently, particularly the intake vents near air filter.
  • Clean the air filter frequently as well, for example every 5 hours of work and even more often when working in dry and dusty environments.
  • Don’t forget to check also the tank, fuel tubes and filter occasionally (see the video above).
  • Before adding fuel to the tank, let the engine cool down to prevent fire.
  • And if you own a 4-cycle machine, check the oil level frequently and also change the oil when it becomes dirty (once a season if you don’t use it very often). You can get an idea how to do that in the following video, for exact instructions please follow your manual.

If you plan not to use your string trimmer for more than a month, it’s also a good idea to add stabilizer to the fuel – see the next section:

Finally, the season has ended and your trimmer goes to sleep. So how to prepare it to prevent rust or clogging the fuel system?

  • Clean the unit thoroughly of debris and dirt
  • Instead of draining the fuel, add a stabilizer to a full tank of fresh gas and run the engine for a few minutes to distribute the mix through the fuel lines and carburetor.

  • If you own a 4-cycle machine, change the oil to help prevent rusting.
  • Store it in a clean, dry area.
