Wacker EH-9
Maintenance-free time is money!
The innovative magic drilling and chiseling hammers save money because they lose no time due to maintenance and failures: The three-phase AC motor means that there is no changing of worn-out carbon brushes. Failures due to burnt-out windings in the rotor of the motor are likewise a thing of the past. On the other hand, the built-in frequency inverter is a very useful feature, since it means that magic electric hammers can be plugged in to a standard 230 V mains socket.
