Restring a Dewalt Weed Eater: Detailed Guideline

Ensuring your lawn care tools are ready for action is a year-round commitment. One essential skill to master is restringing a weed wacker when it inevitably runs out of string.

By understanding this simple task, your weed eater will remain perpetually equipped to handle any weed or grass it encounters.

While purchasing a new pre-strung replacement trimmer head might seem convenient, it can prove costly. Restringing your existing trimmer head is incredibly straightforward and cost-effective, making it the practical choice. 

So, save your wallet and learn this effortless technique to keep your weed wacker in optimal working condition at all times.

Step-by-Step Guideline

Preparation:

What You Need:

A trimmer Line, scissors, and a pole or any Pole-like object  

Know Your Trimmer:

Changing the line on your Dewalt weed eater depends on the model you have. Some models, like DCST920, DCST970, and DCST991, come with the new QuickLoad spool head, making it simple to reload the line without taking it apart. 

To check, just look at the spool- QuickLoad spools have a flat bottom, while traditional ones have a bump knob.

Choose the Right String Size:

Selecting the correct string size for your Dewalt weed eater is crucial for optimal performance and avoiding damage. 

The Dewalt 20-volt trimmer requires dual 0.080-inch cutting lines, and using a different size can not only degrade performance but also strain the engine, potentially causing harm to your trimmer.

Precautions:

Before restringing the worn-off trimmer line, let the weed eater cool down before restringing to avoid burns.

Now that the necessary preparations have been taken, you can start the restring process for your Dewalt weed eater.

Step 1: Removing the Spool

• Take off the batteries. Running the trimmer until it runs out of gas, removing the battery, and unplugging any power sources are essential to prevent injury and damage to the trimmer head.

• Locate the white indicator knob and turn it clockwise while pushing it down to unlock it from the spool window. If the knob is difficult to turn, try spinning the trimmer head from right to left to unlock the indicator knob.

• Carefully pull out the trimmer head (spool cap), ensuring your owner’s manual doesn’t indicate otherwise to avoid damage.

Step 2: Preparation and Cleaning

• Remove the old trimmer line and clean the spool cap, clearing out any debris or grass clogging the trimmer.

• Check if the holes in the trimmer head align in a straight row, you should be able to see all the way through the head. Note the winding direction marks for later reference.

Step 3: Trimming and Installation

• Cut about 20-30 feet of trimmer line if it doesn’t come pre-cut.

• Find the mid-point. In order to do that, take both the loose ends, and make it go around the pole, or any pole-like object. Now taking the two ends of the line, pulling tight you get the midpoint. 

• Put a mark at the midpoint according to your convenience for future reference. 

• Start winding by hooking the midpoint into the center notch. 

• Insert the trimmer line into the jam hole and wind it according to the indicator arrow on the trimmer head until fully installed, leaving 2 to 3 inches of line outside the head.

• For dual-feed trimmer lines, repeat the winding process on the other end. 

Step 4: Final Locking and Verification

• Once both feeding lines are in place, push the spool cap down onto the trimmer until you hear the indicator knob click into a locked position.

• If the knob doesn’t click automatically, adjust it until you hear and feel the locking click.

However, the steps are a bit different if your weed eater has a traditional head with a dual-sided spool.

How to Restring a Weed Eater with Traditional Head

• Follow the step 1 & 2 the same way mentioned above. Next, start by winding the new line in the groove of the spool that is closest to the holding slots. Insert the end of the cutting line into the retaining hole.

• Wind the cutting line onto the spool following the arrow’s direction at the bottom of the spool. Make sure to wind the line neatly and in layers, avoiding any crisscrossing. 

• Once the wound-cutting line reaches the starting point of the holding slots, cut it to approximately 4 inches (106 mm) in length.

• Hold the first line in the holding slots on one side of the spool, then wind the second line using the same procedure on the lower section of the spool. 

• After both lines are wrapped around the spool, use your thumb and finger to secure them in the holding slots. Feed the ends of each line through the two holes on either side of the head in the spool housing.

• Align the white projections inside the spool housing with the corresponding recesses in the spool. Position the holding slots as close as possible to the two holes. 

• Insert the spool into the housing and turn it counterclockwise to lock it in place. Make sure the white projection is visible in the spool window and prevent the line from unwinding and wrapping around the shaft below the spool.

• To release the lines from the holding slots, pull both ends of the cutting line. If the line extends beyond the cutting blade on the guard, trim it so that it just reaches the blade.
