How To Use A Weed Burner Correctly

 As weeds grow more and more lush in the gaps between gardens and sidewalks, many people choose to use weed burners to burn them. However, some people often make incorrect operations during the use of the weed burner, which can lead to the burner not being able to ignite and not working properly. Below, Hardell will explain how to use the weed burner correctly, hoping to help those first-time users.

STEP 1. Connect the weed burner torch, hose and propane tank

Correctly connect the weed burner torch, hose, and propane tank together. It should be noted that before connecting, the valves of the weed burner torch and propane tank must be in a closed state; The connection must be tightened to prevent propane leakage.

STEP 2. The weed burner torch is diagonally aimed at the ground and 8 inches high

After starting to use the weed burner, the nozzle of the weed burner should be tilted (45 degrees) towards the ground, with a height of approximately 8 inches from the ground. It should be noted that do not lift the weed burner flat, as propane gas is heavier than air and can flow downwards, causing it to not ignite.

STEP 3. Open the valve of the weed burner torch and the valve of the propane tank

Open all the valves in the propane tank, then slightly open the valve on the torch of the weed burner. At this point, you can hear the sound of gas. It should be noted that the valve opening range of the weed burner torch should not be too large. Firstly, when igniting, it is easy for the flame to be too large, which poses a threat to the safety of the user. Secondly, if the gas is too large, it is easy to extinguish the spark and cause the ignition to fail. It is best to open the valve of the weed burner torch by about 15 degrees.Related reading:Best weed burner

STEP 4. Push button ignitor

The next step is to push button ignitor. At this point, you can see that the nozzle of the weed burner torch has flames generated. If not, you can push button ignitor multiple times. It should be noted that do not use the idle boost control lever at this time to prevent the occurrence of ignition failure.

STEP 5. Increase the valve of the weed burner torch and use the idle boost control lever

Increase the valve of the weed burner torch to allow more propane gas to pass through, thereby increasing the flame of the nozzle. Operate the idle boost control lever to make the flame longer, making it easier to ignite weeds in the gaps. It should be noted to stay away from flammable materials and not aim the torch at people and animals.Related article:How to use weed puller

STEP 6. Close the valve of the weed burner torch and the valve of the propane tank

After use, first close the valve of the weed burner torch, and then close the valve of the propane tank. Because some weed burners do not have the function of preventing backfire. If the propane tank valve is closed first, it is easy to experience tempering. But you don't need to worry about these things happening. The Hardell weed burner has a special setting on the weed burner torch, so even if you close the propane tank valve first, there won't be any flashback.

STEP 7. Disassemble the components and place them in a safe place

Remove the weed burner torch, propane tank, and hose to a safe place and prevent children from coming into contact.

I hope that through the above article, you can have a full understanding of the correct use of weed burners and help you use them correctly. If your family is still struggling with weeds, you can choose a Hardell weed burner, which is safe and reliable, and can be connected to a converter (purchased separately), allowing you to directly connect to a pound propane tank, making your weed burning process easier.
