My Cordless Grass Trimmer is having issues with the speed

Quick Answer

If your cordless grass trimmer is running slower than normal or has lost cutting power, the most common causes are blocked ventilation slots, an incorrectly fitted spool, the wrong cutting line, or a worn spool.

Checking these components will often restore normal performance.


Before You Start

Before inspecting your grass trimmer, 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 cutting head
  • Work on a clean, stable surface
  • Refer to your user manual for the correct line specification

Important: Never carry out maintenance while the battery is installed.


How to Improve the Trimmer Speed

Follow these steps to identify and resolve the issue.

1. Check the ventilation slots

Inspect the motor vents for:

  • Grass clippings
  • Dust
  • Dirt or debris

Blocked vents can restrict airflow and reduce motor performance.


2. Check the cutting line

Ensure you are using the correct line for your model.

Most models require a line diameter of 1.2 mm, but always refer to your user manual for the correct specification.

Using the wrong size line can reduce cutting performance and affect motor speed.


3. Inspect the spool

Remove the spool and check that:

  • The line is wound correctly
  • The line feeds freely
  • The spool is not damaged or excessively worn

An incorrectly wound spool can create resistance and slow the trimmer.


4. Try the spare spool

If your grass trimmer was supplied with an additional spool and line, install it and test the machine again.

This helps determine whether the original spool is causing the problem.


If the Problem Continues

If you have completed all of the above checks and the trimmer is still running slowly:

  • Contact our customer service team via Live Chat
  • Or submit a support ticket with your model number and a description of the issue

Our team will be happy to assist with further troubleshooting.


Important Maintenance Tips

  • Keep the motor vents clean after every use
  • Always use the correct line diameter for your model
  • Replace worn or damaged spools promptly
  • Store the trimmer in a clean, dry place
  • Regularly inspect the cutting head for signs of wear

Frequently Asked Questions

Why is my cordless grass trimmer running slowly?

The most common causes are blocked air vents, an incorrectly wound spool, or using the wrong cutting line.

What line should I use?

Most cordless grass trimmers use 1.2 mm trimmer line, but you should always check your user manual for your specific model.

Can the spool affect the trimmer speed?

Yes. A damaged or incorrectly wound spool can create extra resistance and reduce cutting performance.

Why should I clean the ventilation slots?

Blocked vents reduce airflow to the motor, which can cause overheating and lower performance.

What should I do if none of these steps work?

If the problem persists after completing these checks, please contact our customer service team for further assistance.

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

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.

My Cordless Grass Trimmers spool line keeps breaking too often

Quick Answer

If your cordless grass trimmer line keeps breaking, the most common causes are an incorrectly wound spool, using the wrong line diameter, or cutting material that is too thick for a grass trimmer.

Checking the spool installation and using the correct line for your model will usually resolve the issue.


Before You Start

Before inspecting the spool, 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 cutting head
  • Work on a clean, stable surface
  • Refer to your user manual for the correct line specification

Important: Never carry out maintenance while the battery is installed.


Why the Trimmer Line Keeps Breaking

Common causes include:

  • The line is incorrectly wound onto the spool
  • The wrong line diameter has been fitted
  • The spool is worn or damaged
  • The trimmer is being used on thick or woody vegetation
  • The line is old, brittle, or damaged

How to Fix Frequent Line Breakage

Follow these steps to identify the cause.

1. Check the spool

Remove the spool and ensure:

  • The line is wound neatly in the correct direction
  • The line is not crossed or tangled
  • The spool is correctly fitted

An incorrectly wound spool can cause the line to snag and break


2. 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 replacement works correctly, the original spool may be faulty or incorrectly wound.


3. Check the line diameter

Ensure you are using the correct trimmer line for your model.

Most cordless grass trimmers use a 1.2 mm line, but always refer to your user manual for the correct specification.

Using a thicker or thinner line than recommended can affect performance and increase breakage.


4. Use the trimmer on suitable vegetation

Grass trimmers are designed for:

  • Grass
  • Light weeds
  • Soft plant growth

Avoid using the trimmer on:

  • Thick weeds
  • Woody stems
  • Shrubs
  • Small branches

Attempting to cut heavy vegetation can cause the line to snap repeatedly.


If the Problem Continues

If the line continues to break after completing these checks:

  • Inspect the spool for wear or damage
  • Replace the line with a new, genuine replacement if necessary
  • 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
  • Replace worn or brittle line before use
  • Rewind the spool carefully to prevent tangles
  • Avoid striking hard surfaces such as walls, kerbs, or fences
  • Only use the trimmer on grass and light vegetation

Frequently Asked Questions
