In 2018 DEWALT introduced our new DWO1DT995 QuickLoad Spool Heads to make adding new trimmer line a breeze! Models that may have the new Spool Head are DCST920, DCST970, and DCST991.
If unsure the head type, an easy way to ID it is by looking at the spool itself. As you see here, the QuickLoad has a flat bottom while the traditional bump has a traditional bump knob.
To install more line on your trimmer:
Cut a maximum 25 foot (8 m) length of trimmer line.
Align spool housing eyelets with the arrow on the spool head as shown below.
Thread one end of the trimmer line through an eyelet. Guide the line through to the second eyelet and continue to pull the line through until there are equal lengths of string on each side of the spool housing as shown here.
Secure the spool cap from moving with one hand. Using your other hand, wind the string onto the spool by rotating the spool head counter clockwise as shown below. Continue winding until 5 inches (127 mm) of string remain on each side of the spool housing.

Once again I've sent several requests for help without any help. I assure you I shall never buy a DeWalt product again. Stihl, here I come
Whom ever came up with this design should have their head examined. Gonna sell this garbage and go find a trimmer with a spool that's easily removed and wrapped. And can carry a wound spare.. idiots.
I have to admit that the design of this is a little funky. Also I'm not impressed if customer service is as bad as the two mentions above.
There is a big design floor, using an open bearing for the strimmer head, where it is only protected by a loose metal cap, held in place by the spool head. This needs to be changed to a sealed bearing.
The instructions for the replacement of the trimmer line are not very clear either. The pre-spooled trimmer line had become tangled in the head itself, which needed dismantling to enable the line to be sorted. There were no instructions on how to do this correctly.
I have had this trimmer for about 5 years and it is still working as it should. I do think the way to ad string is a bit daunting, but this article and a few different people on YouTube make it easy.
I haven't dealt with CS but i did by a couple extra spools to have them preloaded and they are an easy switch with a screwdriver to hold and twist off.
Is this for commercial use NO but for my couple of acres it gets the job done. User error would be my guess if someone is completely unhappy with the product. The price and the ease of use makes it great for me. Plus 5 years so far for sub $100, I'll take it.
It sounds like you're frustrated with the design of the Dewalt 20V DCST922 string trimmer, especially regarding the spool system. The difficulty in removing and wrapping the spool, along with the inability to carry a pre-wound spare, seems to be a major inconvenience for you. If you're looking for a simpler, more user-friendly trimmer, consider exploring models with quick-load spool systems or those that allow for easier maintenance.
