My Cordless Grass Trimmers bump feed/automatic feed is not working

Created by Chris McHale, Modified on Fri, 26 Jun at 2:08 PM by Chris McHale

Quick Answer

If the bump feed or automatic line feed on your cordless grass trimmer is not working, the most common causes are an incorrectly wound spool, the wrong type or diameter of cutting line, or a worn spool.

Checking the spool installation and using the correct trimmer line will usually resolve the issue.


Before You Start

Before inspecting the cutting head, make sure:

  • The trimmer is switched off
  • The battery has been removed
  • The cutting head has come to a complete stop

Always:

  • Wear protective gloves when handling the spool
  • Work on a clean, flat surface
  • Refer to your user manual for the correct line specification

Important: Never carry out maintenance with the battery installed.


How to Fix the Bump Feed or Automatic Feed

Follow these steps to troubleshoot the issue.

1. Check the spool

Remove the spool and inspect it to ensure:

  • The line is wound neatly in the correct direction
  • The line is not tangled or crossed
  • The spool is correctly fitted into the cutting head
  • An incorrectly wound spool can prevent the line from feeding correctly.

    Try the spare spool
    If your trimmer was supplied with an additional spool and line:


  • Install the spare spool
  • Test the trimmer again 

If the spare spool works correctly, the original spool may be worn or incorrectly wound.


Check the trimmer line

Ensure you are using the correct line for your model.

Check that:

  • The line diameter matches the specification in your user manual
  • The line type is suitable for your grass trimmer

Using an incorrect line can prevent the bump feed or automatic feed mechanism from operating properly.


If the Problem Continues

If the line still does not feed correctly after completing these checks:

  • Inspect the spool housing for signs of damage or excessive wear
  • Check that the bump feed mechanism moves freely
  • Contact our customer service team via Live Chat or submit a support ticket for further assistance

Important Maintenance Tips

  • Always use the recommended line diameter for your model
  • Rewind the spool carefully to prevent tangles
  • Replace worn or damaged spools when necessary
  • Keep the cutting head clean and free from grass build-up
  • Regularly inspect the feed mechanism for wear

Frequently Asked Questions

Why isn't my trimmer line feeding?

The most common causes are an incorrectly wound spool, tangled line, or using the wrong line diameter.

What line should I use?

The correct line depends on your model. Refer to your user manual for the recommended line type and diameter.

Can a worn spool stop the line from feeding?

Yes. A worn or damaged spool can prevent both bump feed and automatic feed systems from working correctly.

Should I try the spare spool?

Yes. If your trimmer was supplied with an additional spool, fitting it is a quick way to determine whether the original spool is faulty.

What should I do if the line still won't feed?

If the problem continues after checking the spool and line, please contact our customer service team for further assistance.
