Clean and Maintain the Tool
- Use compressed air to blow out dust from vents and motor housing.
- Wipe down the exterior with a dry cloth to remove dirt that could trap heat.
- Check for damaged or clogged cooling components and replace if necessary.
Ensure Proper Battery Use
Use the recommended batteries, such as the DEWALT 20V MAX 5 Ah Lithium-Ion Batteries, and avoid using damaged or old batteries which can generate excess heat. Always remove batteries if the tool is not in use for an extended period.
Prevent Overloading
Match your tool’s capabilities to the task. For example, avoid forcing the drill through tough materials without proper bits or reducing the speed setting to prevent overheating.
