6 Structure and function
6.1 Application
Use the machine only as intended, see chapter Safety, Proper use.
6.2 Functional description
Principle
The machine is a demolition hammer with a pneumatic percussion system.
It is driven by an electric motor.
The rotary movement of the drive engine is converted into a stroke movement
via a transmission and a crank gear.
The piston is moved forwards and backwards by the crank gear, this compresses
the air (forward movement) or generates a partial vacuum (backward
movement). Due to change in pressure the percussion piston is moved forward
and backwards (air cushion percussion system) and hits the tool.
