How to disassemble a hammer drill

Troubleshooting
When inspecting a hammer drill, they usually start with the power cord and plug. To begin with, it is enough to inspect it. For more accurate diagnostics, use a car or household ammeter or multimeter.

If a fault is detected in the cord, it is replaced entirely, selecting or purchasing a new one with a wire cross-section corresponding to the energy consumption of the device.

If it is found that the cord is not damaged, proceed to diagnostics of the internal structure of the tool. The main faults of the hammer drill tool are divided into:

failures in mechanical units and components;
failures in the electro-dynamic "stuffing".
Mechanical failures
If you can hear the sound of the engine rotating, but the belgium telegram data device does not perform its functions, this means that there are problems with the mechanical “stuffing” of the tool:

the impact force does not transfer to the cartridge or to the nozzle, i.e. it stops hitting and the impact disappears;
the rotation of the axis is stopped;
hammers, but does not twist;
works only in one position;
the nozzle slips in the chuck clamps or, conversely, jams after work.
Electrical failures
When the device is plugged into the network, but when you press the start button the engine does not respond or starts to work with failures, overheating or strange extraneous sounds - it is possible that the hammer drill is faulty in its power unit:

a humming sound is heard, but the rotor shaft does not rotate;
crackling and sparks are observed on the graphite brushes;
the body heats up or melts, and there is a burning smell from inside;
does not turn on;
When the tool rotates, acrid fumes and black smoke come out of the motor.
In order to repair the power unit, the master must carefully observe safety precautions. Before removing the casing and starting to disassemble the drive units, the hammer drill must be completely de-energized and checked for residual voltage.
