How To Start A Weed Eater Correctly – A Detailed Guide In 2020

Introduction

A weed eater is a powerful gas trimmer used for cutting grass on the lawn and garden. As a gardener, you surely know how efficient this machine can be, right? Truly, this device can help you save much time doing lawn jobs. However, not everyone knows how to start a weed eater correctly. So we have made this article to explain clearly the right way to turn that machine on. Let’s have a look!

Types of weed eater

Firstly, we want to introduce to you 3 common types of weed eater. To be more specific, they are:

Gas weed eater

A gas weed eater is the oldest version of the grass trimmer among the three types that we want to introduce today. This machine type has been applied to gardening jobs for many decades.

Typically, a gas weed eater has two types of engines. The first one is the 2-stroke motor which uses a mixture of oil and gasoline as fuel to run. On another side, the 4-stroke motor only requires gas. Putting these two engine types in comparison, we would say that the 4-stroke engine runs stronger than the 2-stroke one.

An advantage of a gas weed eater is its flexibility. As you can see, this grass trimmer does not have a cord. So you can bring them from place to place without any problem. Due to this reason, we recommend this tool for trimming grass in a large garden.

Pros

  • Strong engines
  • Flexibility

Cons

  • Makes noise
  • Creates emission

Corded electric weed eater

Unlike the previous product, this device seems to be more environmental-friendly since it is operated by electricity. However, this is also a disadvantage when you have to plug in the power source.

Among the three types we share with you today, this electric weed eater is the lightest one. It is quite easy to understand because this machine is not equipped with a large and heavy motor or a gas tank. In addition, this product does have a battery pack as well.

Another good thing about this electric tool is that it does not make noise while operating. Due to this reason, this electric machine is ideal to use when you have neighbors living nearby.

Pros

  • Not a threat to the environment
  • Lightweight
  • Not making noise during work

Cons

  • Limited flexibility
  • Risk of tripping

Cordless/battery-powered weed eater

This cordless (also known as battery-powered) weed eater is built as a solution to make up for the disadvantages of both corded and gas grass trimmers. More specifically, this machine uses electricity to avoid creating fume to the environment. And for flexibility, the user does not have to plug the machine into the power source during work.

On the weed eater, there is a rechargeable battery pack. If this battery is fully charged, you can bring the weed eater to anywhere you want. When the machine runs out of energy, you can refill the pin pack with electricity again.

Pros

  • Being eco-friendly
  • Good mobility

Cons

  • Taking much time for the battery to be fully charged

How a weed eater work

In order to know how to operate a weed eater (or how to use a string trimmer, whichever you like to call it), you must first understand the operation of each machine part. Therefore, we will explain shortly about this device operation. Scroll down to see!

Motor operation

In most gasoline weed eaters, every time you pull the cord to run the motor, the flywheel magnets will give energy to the ignition, so that it can transfer electrical current to the spark plug. After that, the spark plug will fire and ignite the fuel in the combustion chamber in order to drive the crankshaft.

On another side, the electric and battery-powered device operates in a different way. More specifically, right after the trimmer takes energy from the power source, the electrical current coming from this source will immediately rotate the flywheel and move the crankshaft.

Gear Box

As the motor operates, it will run a gear system (also called GearBox). This system includes an engine clutch that is linked to a drum. The drum is connected to a drive shaft that is placed in a specific pole of the trimmer. When the system is powered, the shaft will rotate quickly to control the trimmer head.

The grass trimmer head

When this head takes energy from the driveshaft, the head spins at a super high speed and releases the lines to trim through the grass. Depending on the head and the lines, you can cut small and large grasses.

Alright, you don’t have to wait any longer, do you? Here comes our guide on how to start a weed eater!

Starting a gas weed eater

Step 1: Find the right area

Place your machine on a flat and dry surface. Keep in mind that fewer obstacles around your work position, the more comfortable you can do the job.

Step 2: See the gas tank

Make sure that the gas tank is already closed up. If it is opened, the fuel may flow out during your work.

Step 3: Turn on the device

Every trimmer has a switch that says “on/off”. Find the switch and turn it on, so that the motor can receive electricity to operate.  

Step 4: Turn the choke on

In order to run, the motor must reach a specific heat. If the instant temperature of this motor is so slow, the machine is unable to start. A solution to this problem is to turn the choke to the right position so that it can prevent the air from flowing into the motor. 

Step 5: Tap the purge valve

Tapping the purge valve will deliver the fresh gas to the machine carburetor. All you have to do is to find this valve and tap it for about 5 – 6 times.

Step 6: Pull the trimmer cord

Typically, this cord ( also called throttle lock) is usually placed on top of the shaft. Put your hand on the throttle lock of the trimmer, hold it, and pull it out for a few times. When the motor runs, you can stop pulling.

Step 7: Let the motor runs

If the motor already runs, you should turn the choke off and bring the airflow into the motor in order to lower the consumption of the fuel. Also, the airflow will help to keep the motor running ergonomically.

Starting an electric (or battery-powered) weed eater

Step 1: Plug the weed eater into an energy source

As we have mentioned above, all the electric weed eaters require electricity to run. So, you have to find a power source and plug the weed eater into it. Make sure that the connection is stable because the machine may stop working if the plug falls out.

Step 2: Check the energy in the battery

If you use a battery-powered weed eater, you should check out if the machine has run out of power or not. If there is no power left or the amount of energy is too low, you should charge the machine before working.

Step 3: Pull out the trigger

After completing the two steps above, you have to pull out the trigger to run the device. 

Note: Since the trimmer receives power, it will start running immediately. If you are not careful, you may get some unexpected accidents. Due to this reason, the switch of the trigger must be turned off while you connect the weed eater to the power source! Right after the plugging in is completed, you can pull out the trigger later.

Conclusion

Our guide on how to start a weed eater has come to an end. After all, bringing the grass trimmer into work is totally not difficult, right? Just follow our steps carefully and you are able to start working.
