How to use

Before use, ensure a compatible DeWALT battery is fully charged and fitted according to the battery release mechanism. Select an appropriate collet accessory up to 6 mm and secure it in the spindle following the manufacturer's instructions for tightening. Hold the grinder with a firm grip and start the tool at no-load to check accessory balance. Apply light, steady pressure when grinding; allow the tool's speed to perform most of the work and avoid forcing the accessory into the workpiece. After completing the task, switch off the tool, wait for the spindle to stop, and remove or store accessories safely.

Recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and gloves. Match accessory type and maximum diameter to the task and the collet size. Avoid prolonged continuous use without breaks to prevent overheating and minimize operator fatigue. Store the tool in a dry, cool place and follow DeWALT guidance for battery care and accessory maintenance.
