String Trimmer: You Need to Know

# How to Use a String Trimmer Properly?

Ans. The only important thing to know about a string trimmer is that it cuts better depending on the way it spins.

If it spins clockwise (to the right), you’ll make the right trying to cut towards your left for better results.

The same happens the other way around. But this is also important not only because it cuts better that way, but because any debris in the path of the tip or line will get ejected.

# How to Replace Trimmer Line Black and Decker?

Ans. Replacing the line on a battery-powered weed eater is reasonably straightforward, especially on a Black & Decker device which is usually a double-line design. Here’s how to do it;

  1. Remove the battery from the trimmer or just unplug it. Then sit and hold the trimmer with your legs with slight pressure to straighten it.
  2. Then remove the cap or shell from the line head. Typically, it comes with two stabs on the sides you need to depress so that you can lift the lid off.
  3. Pull the old string/line out or cut it accordingly. Make sure to have the 0.0065-inch monofilament line ready so you can cut it, measure it, and install it where the old one was.
  4. Now insert the line on the holes and wind the string until you have 6 inches left on each side. Hook the string on the according notch and tighten it up.
  5. Now just set the cap back in the line head and make sure it locks well. Then you’re ready for trimming once again.

# How to Put Line in a Weed Eater?

Ans. The winding process of putting a line in a cordless string trimmer is usually the hardest or most annoying part of replacing the line. However, it is entirely easy if you know how exactly.

To do it, you just need at least 20 feet of 0.065 line or the desired diameter according to the device. And the spool of the device ready with no old line in it.

Simply attach the 20-feet new line on the two holes of the spool, and making sure it is tight enough, start winding along with the reel of the device. Make sure the 20-feet line has two ends so that you can fit them both on the spool accordingly.

After a few seconds or minutes, you will have the line already winded on the spool and ready to be used on the weed eater. Then just install the reel and make sure it is tight so you can use the trimmer without problems.

# How to Use a String Trimmer Like a Pro?

Ans. To use a trimmer like a professional and always make the right cut at the right moment without drawbacks, you need to know a few techniques. Here we go over each of them for you to learn;

Tapering: It’s all about moving the cutting line in an angled way so it can cut more tightly and with a blended finish. This is perfect when cutting around walls, fences, or trees.

Scything: Merely bring the line back and forth making a U movement when cutting. This is mostly done when there’s a lot of grass to cut and no rule to follow.

Screeding: This is all about cutting as precisely as possible on walkways or driveways. For those little pieces of grass that grow in cracks or tiny green spaces, you just bring the cutting line as low as possible without touching the pavement and entirely straighten.

As evenly as possible, just cut the grass as low as you can.

# How To Use String Trimmer as Edger?

Ans. Similar to tapering, using a trimmer as Edger is mostly done on connections between the grass and other large objects such as streets or walkways. You just move the trimmer line, so it cuts in a vertical way instead of horizontal parallel to the floor.

This way, you can cut unfinished grass and leave a crisper edge. Yet, this way also pulls dirt and rocks, so be careful.

# How to String a Weed Eater with Two Holes?

Ans. This is done the same way you would do a single weed eater. However, you will have to find a string with two loose ends so you can fit each on the spool and start winding.

The rest of the process is the same as any other trimmer out there.

# Can I Use a 40v Battery in a 20v Tool?

Ans. Unless you configure the whole circuitry and connections within the trimmer, using a 40v battery on a 20v tool is almost impossible.

Of course, you can make it work for a few seconds maybe, but after that, you will probably burn out the device entirely.

# What is the Best String Trimmer Line?

Ans. The best line is always a professional grade 0.065 diameter one. However, depending on the device, a 0.080 or 0.050 can be the best choice.

# Electric vs. Gas Trimmer?

Ans. Electric is way lighter and much more convenient, yet it does not last as long per operation. A gas trimmer instead, offers slightly more power and lasts more time but with a heavier build. If you want to know the electric hedge trimmer then check Gardengrower.

# What is a Brushless Trimmer? Is a Brushless Motor Better?

Ans. A brushless trimmer comes with a motor-free of brushes and commutators, plus it has reversed magnets. These parts make the engine noisier, less energy-efficient, and sometimes even weaker or less powerful.

A brushless motor is then quieter, uses less energy, and sometimes provides better performance overall. This makes a brushless trimmer way better.
