Why does the Mijia Brushless Cordless Drill 2 produce a loud noise when running?
If the Mijia Brushless Cordless Drill 2 produces a loud noise when running, please refer to the following steps to troubleshoot:
1. If the power drill is brand new or has never been used, the gearbox hasn't been used either, and the grease hasn't fully coated the gears, which can cause some noise. The noise will disappear after the machine has been used for a while.
2. If the drill bit is not securely installed, severely worn, or bent, it can cause vibration and abnormal noise. Please ensure all parts of the drill are securely installed or replace the drill bit and check if the problem is resolved.
3. If the drill is used at a high speed on unsuitable materials, it will produce noticeable noise and vibration. Please adjust the speed or change the material and see if the noise is reduced.
4. If the lubricating oil in the gearbox dries up, it will increase friction between the gears and produce a sharp noise. Please add lubricating oil and check if the problem is resolved.
5. If the screws are loose, the components will collide due to vibration during operation, causing noise. Please tighten the screws and check if the noise subsides.
6. If the issue persists, please contact the after-sales service center for further assistance.
