Worx WG155 trimmer/edger Parts

Worx “free spools for life” is a promotional offer that provides replacement trimmer spools under the offer’s terms; the exact eligibility, quantity, and any shipping or handling charges depend on the promotion details tied to your purchase. For a WG155 trimmer/edger, the most important step is using the correct spool type and installing it correctly per the WG155 owner's manual.

What to verify before you request a spool

We recommend confirming the offer details first, then matching the spool to your trimmer.

• Confirm your trimmer model number is WG155
• Check the promotion terms that came with your trimmer (or your registration confirmation)
• Match the spool identifier on the packaging exactly (letters and numbers)
• Use the correct trimmer line size for this model
• Install the spool so the line routes cleanly through the eyelet

WG155 line size and why it matters

The WG155 is designed to use trimmer line up to a maximum diameter of 0.065 inch. Using thicker line can cause poor feed, jams, and extra wear.

Item	WG155 guidance
Maximum line diameter	0.065 in
Best practice	Use a prewound replacement spool or wind neatly and evenly

Installation and feed checks (from the manual)

Correct installation prevents most “it won’t feed” complaints.

• Turn off the trimmer and remove the battery before servicing
• Press and hold the two latches to remove the spool cap
• Clear broken line and debris from the spool holder
• Pull the line through the eyelet, then seat the spool correctly
• Refit the cap firmly and confirm it locks in place

If the line feeds too much or not at all

These adjustments restore normal cutting quickly.

• Too much line fed out: remove the cap and turn the spool counterclockwise until the line is the desired length
• Line will not feed: manually feed line; if it still will not feed, remove the spool and rewind the line or replace the spool

Why it matters

Using the correct spool and 0.065 inch line keeps the automatic line feed working efficiently, reduces tangles, and helps your Worx WG155 cut consistently.

A string trimmer is the generic tool name; “Weed Eater” is a brand name that many people use as a nickname for any string trimmer. Your Worx WG155 is a string trimmer (also called a line trimmer), even if someone casually calls it a weedeater.

Quick definitions

• String trimmer / line trimmer: The tool type; it cuts grass and weeds using spinning nylon line.
• Weed Eater: A brand name that became a common term for the tool type.
• Trimmer/edger: A string trimmer that can also edge along sidewalks and driveways.

How this applies to the Worx WG155

The WG155 uses nylon cutting line and a trimmer head system; it is designed for 0.065 in (1.65 mm) line diameter for proper feeding and safe operation. For operating details and line loading steps, use the WG155 owner's manual.

Common WG155-RELATED terms you might see

• Trimmer head, spool, eyelet, line cutter
• Safety guard and flower guard
• Edger wheel (for edging mode)

Why the wording matters when buying line or troubleshooting

Using the correct term helps you match the right consumables and instructions.

What you search for	What you usually need	WG155-SPECIFIC tip
“Weedeater line”	Nylon trimmer line	Use 0.065 in (1.65 mm) line for proper feed
“String trimmer spool”	Prewound spool or line to wind	Follow the spool winding direction shown in the manual
“Edger mode”	How to rotate/convert the head	Use the edger wheel and align the guard marks

Why it matters

“Weedeater” vs. “string trimmer” is mostly a naming difference, but the line diameter and feed system are not. Using the wrong line size (or wire, rope, or string) can cause poor feeding and create a safety hazard.

A string trimmer cuts grass and weeds with a fast-spinning nylon line, while an edger is used to create a clean, vertical edge along sidewalks and driveways. Your Worx WG155 is a 2-in-1 trimmer/edger, so it can do both jobs.

How each tool cuts

• String trimmer: Uses flexible cutting line; best for trimming around fences, trees, and uneven areas.
• Edger: Creates a crisp border; on the WG155, edging is done by rotating the head and using the wheel to guide the cut.
• Cut quality: Trimmers are great for cleanup; edging gives the “straight line” look along hard surfaces.

How the WG155 switches from trimming to edging

The WG155 is designed to change modes by rotating the shaft and positioning the head for edging. For the exact steps and diagrams, use the WG155 owner's manual.

Typical WG155 edging setup includes:

• Rotate the head/shaft to edging position (90 degrees)
• Set the head angle to the lowest horizontal setting
• Put the edger wheel on the ground to guide the edge
• Use the guard’s line guides to track the lawn edge

Quick comparison

Feature	String trimmer mode	Edger mode (WG155)
Cutting direction	Mostly horizontal trimming	Vertical edge cut
Best for	Grass around obstacles	Sidewalk/driveway borders
Control aid	Your hand position and guard	Wheel guidance and line guides

Why it matters

Using the right mode improves results and reduces wear on the trimmer head. For example, the WG155 is designed to use 0.065 in (1.65 mm) line; using the correct line size helps the automatic line feed work properly and keeps edging consistent.
