Introduction

If your WORX 20V Power Share GT 3.0 12" String Trimmer (Model WG163M) stops cutting grass effectively or the trimmer line has worn out, use this guide to replace the trimmer spool.

The trimmer spool is the component that feeds trimmer line through the trimmer head. As the trimmer operates, the spinning line cuts grass and weeds. Over time, the line becomes shorter, breaks, or runs out completely. This happens when the trimmer line rubs against abrasive surfaces causing friction, hits solid objects, or faces an excessive load of grass/weeds. Replacing the spool restores the trimmer’s cutting ability and allows the tool to function normally again.

Common symptoms of a worn or empty spool include the trimmer not cutting grass, and little or no line extending from the trimmer head.

Before you begin this repair, make sure the battery is disconnected. Failure to do so may result in serious injury.

Press and hold down the large orange button on the top of the battery.
While holding the orange button, firmly slide the battery down the handguard of the trimmer to disconnect it.
Removing the battery ensures the device cannot unintentionally activate mid repair, skipping this step may result in serious injury.

Step 2

Flip the trimmer upside down so the bottom of the guard is facing upwards before starting to work on the trimmer.
If your trimmer is not lying flat, step down firmly on the top of the guard and firmly push the handle down until the handle lies parallel to ground.

Step 3

Pinch and hold the orange tabs on the side of the spool cap.
While squeezing the spool cap, firmly lift the cap until it separates from the spool housing.

Step 4

Lift the empty trimmer spool out of the spool housing.

Step 5

Without unraveling the entire spool, grab the loose trimmer line from your replacement trimmer spool.
Starting from the inside of the trimmer housing, thread about 2 inches of trimmer line through the hole on the side of the housing.
Continue to thread the line without unwinding it until you reach your trimmer spool.
Push the spool down into place once it reaches the spool housing.

Edit

Step 6

Line up the sides of the spool cap with the grooves in the spool housing.
Push firmly until the cap is in place.
You should hear a click when the cap is properly secure.

Press and hold the line feed button on the side of the spool housing.
While holding the line feed button, pull on the trimmer line until it extends just shy of the line cutter.
The line cutter may be sharp, do not touch the line cutter, you can safely check the length of the trimmer line by holding it a safe distance above the line cutter.
Don't worry if you pulled the trimmer line too far, the line cutter will automatically cut any stray line during regular use.
