无法开机
打开电源开关时,Dremel 4000 没有响应。
开关杆未啮合
虽然工具无法开机的原因有很多,但最常见且简单的问题是检查开关杆是否与电子组件正常啮合。关于如何更换电子组件的指南可以在这里找到。 Dremel 4000 Electrical Assembly Replacement
电源线故障
为了确定电源线是否故障,你需要将其从电子组件上断开并连接到电压表上。关于如何更换电源线的指南可以在这里找到。 Dremel 4000 Power Cord Replacement
电子组件故障
如果工具无法开机,且已检查开关杆和电源线是否完好,则必须更换电子组件。虽然电子组件内部包含多个零件,但整个组件是以一个整体的形式提供的,必须整体进行更换。 Dremel 4000 Electrical Assembly Replacement
工具无法调速
Dremel 4000 可以通电,但无法改变转速。
电子组件故障
如果工具可以开机,但尽管调节了转速旋钮,转速仍固定不变,则必须更换电子组件。虽然电子组件内部包含多个零件,但整个组件是以一个整体的形式提供的,必须整体进行更换。 Dremel 4000 Electrical Assembly Replacement
主轴无法锁定
安装/拆卸钻头时,Dremel 4000 的主轴无法保持锁定状态。
主轴锁定按钮故障
如果即使按压了蓝色主轴锁定按钮,主轴仍然旋转,则需要更换该按钮。关于如何进行此项操作的指南可以在这里找到。 Dremel 4000 Shaft Lock Pin Replacement
工具发出尖叫声或啸叫声
Dremel 4000 在运行时发出啸叫声或尖叫声。
轴承组件故障
如果旋转工具在运行时发出异常声音,且在负载增加时声音变大,则可能是轴承故障。对于此款工具,需要将整个电枢和轴承组件一次性更换。关于如何进行此项操作的指南可以在这里找到。 Dremel 4000 Bearing Assembly Replacement
工具过热
Dremel 4000 在标准操作条件下过热。
通风口被遮挡
检查工具上的四个通风口,确保它们没有被遮挡或以其他方式堵塞。如果通风口没有被遮挡但仍然过热,则可能是机壳内积聚了灰尘,必须将其清理干净。关于打开机壳的指南可以在这里找到。 Dremel 4000 Back Case Replacement
轴承组件故障
如果 Dremel 过热且通风口通畅,请检查轴承组件上的风扇是否正常工作。如果不工作,则需要更换轴承组件。对于此款工具,需要将整个电枢和轴承组件一次性更换。关于如何进行此项操作的指南可以在这里找到。 Dremel 4000 Bearing Assembly Replacement

my dremel 4000 make noise and the temperature fusible (110 ºc) got burned, is a brand new dremel 4000 .
the rotation is not continued is like little jumps, maybe it`s a electronic speed control prblem ??

I had this issue as well. Fixed it by removing one side of the case and blowing out the back end of the "dial" potentiometer with compressed air. It could also be the brush contacts need to be tightened slightly.

changed the fusible, and the rotation is not smooth and make noise again and the fusible gets burned again. the Dremel is brand new and clean. worked fine for some hours.

My dremel4000 was working great but I tried this with a 15mm ply and the 561 bit to make a hole. I kept the dremel running for a long time and it got some goose bumps kind of bubble on the rubber side and stopped working. What would be the problem

The electrical assembly does not necessarily need replacing if the tool does not start when switching it on. The switch design is not very robust. The blue plastic on/off button operates a little microswitch just under the variable speed adjuster. If the blue plastic is not pressing firmly on the microswitch then it can fail to turn on. I just took mine apart and refitted everything and it worked. If it fails again then I will glue a little packing piece on the blue plastic to ensure that everything presses firmly together. That ought to fix it.
