- Maintain Control: Always maintain a firm grip on the tool with both hands.
- Avoid Kickback: Be aware of potential kickback and use the tool in a manner that minimizes this risk. The tool's Kickback Brake and E-CLUTCH system are designed to reduce this risk, but proper technique is essential.
- Battery Safety: Use only specified battery packs and chargers. Do not expose batteries to water or extreme temperatures.
- Ventilation: Ensure adequate ventilation when working in enclosed spaces, especially when generating dust or fumes.

- Inserting the Battery:

Operating Instructions
The DEWALT FLEXVOLT 60V MAX* Angle Grinder is designed for grinding and cutting metal and masonry materials. Always ensure proper safety gear is worn.
- Starting the Tool: To start the grinder, depress the trigger switch. The tool will reach its maximum rotational speed of 9,000 RPM.
- Stopping the Tool: Release the trigger switch to stop the tool. The integrated brake engages, stopping the wheel within approximately 1.5 seconds when using a standard grinding wheel (4-1/2-inch x 1/4-inch bonded abrasive wheel, non-hubbed).
- Kickback Brake Feature: This safety feature engages when a pinch, stall, or bind-up event is detected. The electronic brake applies maximum force to quickly stop the wheel, reduce tool movement, and shut off the grinder.
- Anti-Rotation E-CLUTCH System: This system activates in less than a tenth of a second if a pinch or stall is detected, shutting down the motor to prevent uncontrolled rotation of the tool.
- Grinding Technique: Apply light, even pressure. Allow the tool to do the work. Avoid excessive pressure, which can overload the motor and reduce wheel life.
- Cutting Technique: For cutting, use a thin cutting wheel and make shallow passes. Do not apply side pressure to the cutting wheel.
