Repairing a hammer drill yourself should begin with identifying the cause of the breakdown. And for this, it is not necessary to start with disassembling the tool. The hammer drill device is based on two main units - an electric motor, the power of which is from 650 W and a gear unit. These are the most basic elements of the power tool, the wear and tear of which entails expensive repairs. However, in addition to these mechanisms, the hammer drill may fail:
The network cable is damaged
Button malfunction - depending on its design, the speed controller and reverser also break down
Wear of collector brushes
Cartridge malfunction
The mode switch is jammed or the corresponding mode does not work
It is much more difficult to detect faults in the electrical part oman telegram data of the tool than in mechanical components, so it is recommended to pay special attention to identifying the causes of malfunctions.When there are breakdowns in the mechanics, there are corresponding signs that can be heard - a squeak, crackle or hum of the tool when you press the "Start" button. When there are breakdowns in the electrics of a straight hammer drill, they can sometimes only be diagnosed using specialized devices - a tester, a multimeter. In 80% of cases, it is possible to identify breakdowns of the hammer drill independently by the first signs. In more detail about how to repair a hammer drill with your own hands, we will find out further in detail.
Malfunctions in the electrical part of the tool
Before repairing a hammer drill, you need to understand how to disassemble it. The design of the power tool is such that the protective casing consists of two parts - an electrical part, which includes the handle and electric motor, and a mechanical part, where the gear unit of the tool is located.
