Step 1: Purchase the right line. Make sure you’re using trimmer line that’s the same thickness as the line you’re replacing or a line thickness that’s compatible with your string trimmer.

Using a pair of durable scissors, cut the line so you have a 16-foot length of string. After you've cut your length of line, it's time to start installing it into your trimmer.

DeWalt's line of string trimmers are great for a variety of tasks around the yard, but you'll have to make sure to purchase the correct line size.
