How to properly check and document the situation:
Check operating conditions.
The stated power is specified under standard conditions. Actual performance is affected by the type of material, workload, condition of accessories, and battery charge. Make sure the tool is being used as intended.
Rule out accessories and battery influence.
Dull accessories, unsuitable attachments, or a worn battery can significantly reduce actual power. If the issue persists with new accessories and a fully charged battery, this is an important indicator.
Compare with an identical model.
If possible, compare your tool’s performance with the same DeWALT model used by another person or tested in a store. A noticeable difference may indicate a defect.
Document signs of insufficient power.
Describe specific situations: the tool cannot handle standard tasks, RPM drops sharply, or protection triggers without overload. Photos or videos provide additional evidence.
When it is considered a defect.
If the tool consistently fails to deliver the stated power under normal operating conditions, this may be recognized as a specification mismatch or manufacturing defect.
In this case, it is important to document the issue on Xolvie and then proceed with a warranty claim.
