For example, there is no impact hammer mode.That is, the drill rotates together with the chuck, but does not have an impact action on the working surface. Most often, the cause in this case is a floating bearing. Another reason for this malfunction may be damage to the steel striker. In both cases, the defective part must be replaced.

There are frequent cases when the engine works when the tool is turned on, but the chuck does not rotate. This usually happens because the gearbox is jammed. By the way, it is unacceptable to keep the hammer drill turned on for a long time when the chuck is not working, the motor winding may burn out. The hammer drill will have to be disassembled and the defects in the gearbox eliminated. They can be caused either by damage to the gears or by debris getting into it.



Another defect is that the chuck cannot fix the drill. This problem australia telegram data may occur with a tool that has been in use for a long time.The cause of this malfunction is the wear of the retainer housing mount.

Electrical faults
Serious problems can also be caused by malfunctions related to the electrical part of the hammer drill. By the way, failure in operation can be caused by a trivial lack of voltage in the socket.

By the way, troubleshooting should start with the smaller ones. That is, you need to check the presence of power in the electrical network, the integrity of the wire and the socket.

Generally speaking, if the instrument shows no signs of life, it is likely that the electrical part of the instrument has failed.

No voltage in the power supply network, cable break
To check, you can connect any electrical device. If there is voltage in the network, then you need to check the integrity of the cable.
