Maintaining a neatly trimmed lawn is a point of pride for many homeowners. But even the most reliable string trimmer can lose its edge – literally – when the cutting line wears out or gets tangled. If you own a Husqvarna HU625HWT 22″ Walk Behind String Trimmer, knowing how to replace the line is an essential skill. Let’s break down the process into simple steps!

Before You Begin: Safety and Supplies

  • Put Safety First: Always disconnect the spark plug before performing any maintenance on your trimmer. You’ll also want a pair of work gloves and safety glasses.
  • Gather the Essentials: Make sure you have the correct replacement line (usually a .155 diameter for this model). You may also need a small flat-head screwdriver for assistance.

Step-by-Step Guide

  1. Remove the Old Line:
    • Locate the trimmer head cover and remove it. You might need your screwdriver to loosen screws or clips holding it in place.
    • Inspect the spool and remove any remnants of the old, broken string. Clean out any debris that might have accumulated.
  2. Prepare the New Line:
    • Cut two pieces of trimmer line. Check your Husqvarna manual for the exact length, but it’s usually around 18-3/4 inches for this model.
    • Note any notches or markings on the spool. These guide the line and ensure proper winding.
  3. Wind the New Line
    • Find the center of your first line piece. Insert it through the center hole on the spool, ensuring an equal length of line protrudes from each side.
    • Following the direction of the arrows on the spool (if present), carefully wind one line around its designated section. Keep the winding neat and tight.
    • Repeat with the second piece of line in the opposite winding direction on its respective side of the spool.
  4. Secure the Line:
    • Locate the small notches or slots on the edge of the spool. Slide the end of each line into its corresponding slot to lock it in place.
  5. Reassemble the Trimmer Head:
    • Carefully place the wound spool back into the trimmer head.
    • Thread the line ends through the eyelets on the trimmer head cover.
    • Reattach the trimmer head cover, securing it with any screws or clips.

Pro Tips for Trimmer Line Success

  • Choose the Right Line: Not all trimmer lines are created equal. Stick with high-quality, durable line matching the diameter recommended for your Husqvarna HU625HWT.
  • Prevent Breakage: Avoid hitting hard objects like fences, rocks, or pavement with your trimmer line. It will wear down and break much faster.
  • Store Line Properly: Line can dry out and become brittle. Store it in a cool, dry place out of direct sunlight to improve its lifespan.

And That’s a Wrap!

Replacing the line on your Husqvarna HU625HWT trimmer is a straightforward process that you can do yourself with a bit of practice. This will extend the lifespan of your trimmer and ensure you always have a powerful, clean cut for the perfect lawn.
