Belt Sander's belt comes off

Safety First: Remove the battery or disconnect from power  

Important: Always wear the correct protective equipment before maintenance. Dust mask or respirator P2, FFP2, or N95. 

Ensure belt alignment 
Belt sanders have an overlapping joint that must be fitted correctly. 
• Follow the directional arrows printed inside the belt. 
• Match the belt arrows with those on the tool—incorrect alignment can cause the belt to break at the join. 

Check belt tension 
A loose belt may slip off during operation. 
• Refer to your sander’s manual for proper tensioning instructions. 

Inspect belt condition 
A worn or damaged belt is more likely to come off. 
• Replace the belt if you notice tears, frayed edges, or excessive wear. 

Avoid excessive pressure 
Applying too much pressure can strain the belt and cause it to slip off. 
• Let the sander do the work—apply light, even pressure. 

Clean the tool 
Dust and debris can affect belt tracking. 
• Inspect the tool and clean any build-up using a brush. 
• If significant debris is found, the tool must be cleaned at home before further use.
