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.

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

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.

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

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

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.

• 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.

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.

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

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

“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.

• 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.

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

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.
