    Tips: Rotary hammer electrical failure.

    Rotary hammer electrical faults mainly include open circuit, short circuit and grounding as well as large sparks in rotor commutation ring.

    Open circuit is most likely due to the broken leather thread, which is most common at the root of the handle. In this disconnection, connect power cord of rotary hammer to the resistance of multimeter and press the switch. Then move the root of leather thread by hand, the reading of multimeter will change at this time. In addition, the root of plug is also easy to break, and there are many cases of broken switches. Poor contact of carbon brushes can also cause disconnection.

    There are 2 ways to check for poor contact of carbon brushes. One way is to observe the end surface of carbon brush. If it is smooth, it means the contact is good, otherwise the contact is poor. The other way is to connect the test leads of multimeter to motor terminal. Use two screwdrivers to simultaneously press on brush socket and rotor. If it is turned on at this time, it means that the motor has no fault.
