5 Structure and function
5.1 Scope of delivery
The scope of delivery includes:
Machine.
Operator’s manual.
5.2 Application
Use the machine only as intended, see chapter Safety, Proper use.
5.3 Functional description
Principle
The machine is a demolition hammer with a pneumatic percussion system.
It is driven by a gasoline engine.
The rotary movement of the drive engine is converted into a stroke movement via a centrifugal clutch, a
single-stage spur gear unit, and a crank mechanism.
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.
The hood and operator's controls are decoupled from the percussion system by a spring system. This
spring system keeps vibrations away from the operator's body if he for example presses his body against
the hood while working.
5.4 Variants
The following different versions were specified in the technical data for the device types:
rs – Integrated shut-off device
The machine has an integrated shut-off device for connecting to an external remote cut-off.
Via the remote cut-off, you can switch off several machines from a central location. This is for the safety
of the operators, e.g. in track construction work.
If you wish to use your machine with a remote cut-off, please contact your Wacker Neuson
representative.
rw
The machine is especially designed for use in track construction.
