Demolition hammers with brush replacement indicator

Brush replacement indicator

— this indicator signals the critical wear of the carbon brushes installed in the demolition hammer electric motor. Gradual wear of carbon brushes leads to interruptions in the operation of the engine and, in the end, to the complete impossibility of using the tool — so they need to be changed regularly. The replacement indicator simplifies the task of monitoring the condition of the brushes and replacing them in a timely manner.
