Disassembly and re-assembly of the machine have to be executed by qualified staff only.
Incorrect assembly can lead to danger of accident for the operator and to defects on the
machine. Additionally to the measures described before, it is a must to check the grease in
the gear and to fill it up or replace it, if necessary. The correct quantity of grease (20 g) is very
important with regard to good lubrication and low warming.
Furthermore we recommend a general overhaul of your hydraulic rotary hammer drill once a
year at the manufacturer, as well as a regular maintenance of the hammer mechanism.
