This article explains the most common causes and basic checks if your electric grass trimmer is running slower than normal or experiencing speed-related issues.
⚠️ Safety Notice
Ensure the grass trimmer is switched off and disconnected from the power supply before carrying out any checks or maintenance.
Possible Causes & Basic Checks
Check the Air Vents
- Ensure the air vents are free from dust, dirt, and debris.
- Blocked vents can restrict airflow and affect performance.
Check the Cutting Line
- Ensure you are using the correct trimmer line for your model.
- Refer to your owner's manual for the recommended line specification.
- Most models typically require a line diameter of 1.2mm, but always check your manual for confirmation.
Check the Spool
- Ensure the line is wound correctly onto the spool.
- Incorrect winding can affect line feed and reduce cutting performance.
Try the Spare Spool
- If your product was supplied with an additional spool and line, try fitting it to determine whether the issue is related to the original spool.
If the Issue Persists
If the speed issue continues after completing the checks above, please contact our Technical Support Team for further assistance.
