Why Restringing Matters
Maintaining your Greenworks Pro Weed Eater includes knowing how to restring a Greenworks Pro Weed Eater properly. Over time, the trimmer line wears down from constant contact with concrete, brick, and thick vegetation. When the line becomes too short or frayed, cutting performance drops significantly. A fresh, correctly installed line restores power and precision to your trimming sessions.
Restringing also prevents unnecessary strain on the motor. A tangled or jammed spool forces the motor to work harder, which can reduce battery life and shorten the tool’s lifespan. Learning this skill saves money and keeps your landscaping projects running smoothly.
Tools and Supplies You Will Need
Before starting, gather the following items:
- A replacement trimmer line compatible with your Greenworks Pro model.
- A flathead screwdriver or the release button specific to your model.
- A pair of needle-nose pliers for handling small parts.
- A clean cloth to wipe away debris.
- A small container to hold screws and springs safely.
Having everything ready prevents interruptions and reduces the chance of losing small components during disassembly.
Understanding the Greenworks Pro Spool System
The Greenworks Pro series uses an auto-feed or bump-feed spool system. The line is stored on a plastic spool inside the cutting head. When the line wears down, the spool rotates to feed out more line automatically or when you tap the head against the ground.
Before restringing, identify whether your model uses a single-line or dual-line configuration. Most Pro models use dual-line for even cutting coverage. Refer to your owner’s manual for the exact line diameter and length specifications.
Spool Removal Process
To access the spool:
- Disconnect the battery or remove the power cord completely.
- Locate the release mechanism on the cutting head.
- Press the release button or use a screwdriver to pry off the cover.
- Lift the spool straight up and out of the housing.
Place the removed spool on a clean surface and inspect the old line for damage or tangles.
Step-by-Step Restringing Guide
Follow these steps carefully to restring your Greenworks Pro Weed Eater:
Step 1: Remove the Old Line
Using needle-nose pliers, pull out any remaining line from both sides of the spool. Check for broken ends or knots that could interfere with the new line installation.
Step 2: Clean the Spool
Wipe away dirt, grass clippings, and debris from the spool grooves and housing. A clean surface ensures smooth line feeding and prevents future jams.
Step 3: Identify Wind Directions
Look for arrows molded into the spool that indicate the correct winding direction. Winding in the wrong direction causes the line to tangle and bind during operation.
Step 4: Cut New Line to Length
Cut a length of replacement line according to your model’s specifications. Typically, dual-line systems require 12 to 16 feet of line. Measure twice to avoid running short midway through the job.
Step 5: Insert Line Through Eyelet
Find the small hole or eyelet on the side of the spool. Push one end of the line through this hole, leaving a short tail of about 2 inches on the outside.
Step 6: Wind the Line
Hold the tail end firmly and begin winding the line around the spool in the direction indicated by the arrows. Keep tension on the line as you wind to prevent loose coils. Fill the spool completely but do not overpack it.
Step 7: Secure the Line
