In this instructional video, Will Kelly demonstrates safe operation techniques for a string‑trimmer (weed eater). He explains how to advance the trimmer line by tapping the spool on a hard surface while applying throttle, emphasizing that this should never be done on a customer's grass because it can damage the lawn. Kelly then shows how the angle at which the trimmer is held determines the direction in which the cut debris (grass, rocks, etc.) is expelled. By angling the tool left, debris is thrown back over the left shoulder; angling right sends debris forward. He illustrates these principles with live demonstrations, stressing the need to avoid windows, vehicles, and other property, and to use hard surfaces (e.g., metal) for line advancement. The overall message is to protect the customer’s property and the operator’s safety by controlling line feed and debris trajectory.

So anytime that you need more string, tap this on the ground on a hard surface and then give it gas. You got to give it enough gas and bang it simultaneously to get more string to come out. Now what you don't want to do is do this in a customer's yard in their grass. I'm going to show you exactly what not to do. As you can see, it starts to build a circle, which— that's a kind of a really bad example, but in a couple days from now it's going to burn. Ideally, you don't want to try to get more whip in a customer's lawn. What I like to do is use a hard surface. So if I see there's a, there's a piece of metal right here, like, I'll actually tap it down to get more strength. This piece of equipment, you always want to walk forward with whenever you're using it, depending on where you're weed eating, the angle that you hold it will dictate where the debris is going to be shot. So you have to be very careful when you're trying to avoid breaking windows, damaging vehicles. If you hold the weed eater on an angle to the left, this whip spins this way. So if you're angling it to the left, all of this debris is going to get shot back over your left shoulder if you hold it to the left. If you hold it to the right, it's going to shoot forward, right? So let me kind of show you, hopefully in a real life example what that looks like. Because you're standing there, I'm not intentionally going to shoot rocks at you or grass or debris. I'm going to shoot it back this way and I'll show you what that looks like. So as you could see, all of that shot back that way and you did not get hit with any grass. Had I kept my feet here but angled it to the right it would shoot forward. So I'll, I'll show you again. I'm going to angle my feet this way. If I were to hold it to the left, it's going to shoot back at you. But in this scenario, we're going to shoot it forward. Be careful because there's literally a window right there. I don't want to shoot my rocks that way, so I'm actually going to angle it this way so if it hits the side of the metal building, it's probably fine. Keep that in mind anytime that you're hitting grass cracks or there's a vehicle around. You have to be mindful of which way the whip is shooting.
