If the accessories of the Mijia Rotary Tool Kit cannot be installed, please refer to the following information:
1. The accessory size can not match the required 2.35 mm diameter. Please confirm that the grinding head is compatible with the 2.35 mm chuck before installation.
2. There can be foreign objects or debris inside the chuck, which can prevent proper insertion. Power off the tool and clean the inside of the chuck before reinstalling the accessory.
3. The grinding head may be worn or damaged, making installation difficult. Replace the accessory with a new one if signs of wear are present.
4. The installation method may be incorrect. Insert the grinding head fully and rotate the chuck nut clockwise until it is securely tightened.
