Proper and careful usage will not only prolong the lifespan of a walk-behind string trimmer but also keep you safe. You should keep in mind that any tool can be dangerous if used improperly.

How to Start Walk-Behind Weed Trimmer?

There are certain guidelines that must be followed before starting the mower. In this article, I’ll provide step-by-step instructions for starting it and some common mistakes people tend to make.

1. Fueling wheeled trimmer

Despite their effect on the environment, most of the mowers are gasoline-powered. And to start a lawnmower easily, you need to take into account the rules for refueling the device with fuel, as well as some other important nuances.

Only gasoline models need refueling before starting since their engine does not work correctly or doesn’t start at all without correctly selected fuel. Therefore, after studying the technical characteristics of your device, you also should find some information about the ready fuel or prepare a special mixture on your own.

Remember that regardless of the mower model and the type of fuel tank, refueling must be done in the same way. You shouldn’t fill in the fuel to the fullest but leave approximately 1.5 inches to the edge of the tank.

2. Starting a walk-behind weed eater

Depending on the model of the lawnmower, you should start it in different ways. Therefore, it is necessary to take into account the individual technical characteristics of the device.

Before starting the engine, switch off the ignition and transmission systems and turn the engine shaft with the starter. After that, you can start launching, proceeding as follows:

  • First, turn on the ignition.
  • Close the air damper (choke).
  • Push the primer button a few times.
  • Pull the starting rope gently (it might take a few tries).

After starting, you need to set the idle speed on the device by using the throttle lever. Then, with the same lever, you have to switch the device to work at low revs so that the engine warms up. After that, you can safely start operating the lawnmower at full power.

3. Common mistakes

The main reason for problems when starting the lawnmower might be the lack of gasoline in the fuel tank, or there is not enough gas to operate the device. In this case, it is obvious that you should fill the tank with fuel, and it is necessary to check the gasoline in advance to prevent such a situation.

By neglecting the rules while preparing fuel mixtures and using low-quality materials to save money, you can also face some problems when starting and operating the lawnmower. To avoid it, you need to carefully choose the ready fuel and the recipes when preparing the mixtures on your own.

FAQ About Wheeled String Trimmer

A lawnmower is not a simple tool to operate, and even professional gardeners might have some problems while maintaining it. Needless to say that the beginners may have tons of questions about it. In this section, I will answer the most common questions about mowers to help you clarify how to start a walk-behind string trimmer.

How do you put a string on a walk-behind trimmer?

First, you have to switch off the engine and wait a few minutes for it to cool down. Pull out the old cutting line after making sure there is no grass stuck to it and the cutting line holder. Then you have to adjust a new cutting line: it should be 23 inches long. Make sure the cutting line holder is not damaged. Push the cutting line inside and start your weed eater on wheels.

How do you start a trimmer that won’t start?

If the trimmer does not start, try to push the primer button and pull on the starting rope a few times more. If this doesn’t help, I recommend to:

  • read the instruction manual carefully;
  • study in detail the method of the first start-up and running-in of petrol cutters;
  • try to understand how the trimmer works, how gasoline is pumped up, etc.

The most common reasons for the malfunction of petrol cutters are as follows:

  • the quality of gasoline is poor;
  • the incorrect proportion of gasoline and oil;
  • clogging of the fine filter;
  • the spark is gone.
