How to use

Fit an appropriate accessory into the collet or chuck according to the accessory manufacturer’s instructions and secure it tightly before operation. Hold the tool with a steady grip and select a suitable speed for the material and accessory; start at lower RPM and increase as needed to avoid overheating or damaging the workpiece. Use controlled, steady passes for cutting and grinding, and apply light pressure when polishing to achieve even finishes. Allow the motor to come to a complete stop before changing accessories or setting the tool down.

Usage recommendations

For best results, match accessory type and speed to the task and material: use cutting wheels for thin materials, grinding stones for shaping, and polishing compounds with cloth or foam attachments. Wear appropriate personal protective equipment such as safety glasses, dust mask and gloves, and ensure good ventilation when working with dust or fumes.
