How to use

Connect the rotary tool to a compatible AC 220–240 V outlet and select an appropriate collet and accessory for the task. Secure the chosen collet into the spindle collar, fit the accessory firmly, and set the electronic speed control according to the material and operation: lower speeds for delicate work and higher speeds for cutting or aggressive material removal. Hold the compact tool steadily by the housing and guide the accessory with light, consistent pressure; avoid forcing the tool to prevent overheating. After use, allow the motor to stop completely before unplugging and store the tool and accessories in the supplied polypropylene case.

Usage recommendations

Use appropriate protective equipment such as eye protection and dust extraction when cutting or grinding; select the collet size that matches the shank of your accessory to ensure secure clamping and accurate running. For prolonged tasks, allow intermittent cooling periods to maintain motor life and consistent performance.
