Repair of the Einhell bbh 850/1 rotary hammer was needed due to a breakdown of the impact mechanism and a lubricant leak from under the gearbox. In my case, the hammer drill gets very hot and drives grease out from under the gearbox. I had to disassemble the hammer drill, make a liquid gasket and replace the gearbox lubricant. Here are the main parameters of the Einhell bbh 850/1 rotary hammer:
Weight - 6.4 kilograms;
Cartridge type - SDS-Plus;
