My Cordless Lawnmower is having issues with the height adjustment

Quick Answer

If your cordless lawnmower height adjustment is stiff or not working correctly, it is usually caused by debris build-up or lack of lubrication in the adjustment mechanism. Cleaning and lightly lubricating the lever typically resolves the issue.

Important: Always switch off the mower and remove the battery before carrying out any checks or adjustments.

Before You Start

Before working on the height adjustment system:

• Switch the lawnmower off
• Remove the battery
• Remove the safety key (if fitted)
• Place the mower on a stable surface
