1.2 Machine Description and Intended Use
This machine is a vibratory rammer. The Wacker Neuson Rammer consists of a
gasoline or diesel engine, a clutch, a fuel tank, a spring-loaded ramming system, a
ramming shoe, and a handle. The engine transmits power through the ramming
system and ramming shoe, generating percussive impact force to compact soil.
The operator guides and controls the machine from behind using the handle.
This machine is intended to be used for compacting cohesive, mixed, and granular
soils in confined areas.
This machine has been designed and built strictly for the intended use described
above. Using the machine for any other purpose could permanently damage the
machine or seriously injure the operator or other persons in the area. Machine
damage caused by misuse is not covered under warranty.
The following are some examples of misuse:
Using the machine as a ladder, support, or work surface
Using the machine to carry or transport passengers or equipment
Using the machine as a hammer or for other demolition work
Attaching the machine to any other machine
Operating the machine outside of factory specifications
Operating the machine in a manner inconsistent with all warnings found on the
machine and in the Operator’s Manual
This machine has been designed and built in accordance with the latest global
safety standards. It has been carefully engineered to eliminate hazards as far as
practicable and to increase operator safety through protective guards and labeling.
However, some risks may remain even after protective measures have been taken.
They are called residual risks. On this machine, they may include exposure to:
Heat, noise, exhaust, and carbon monoxide from the engine
Fire hazards from improper refueling techniques
Fuel and its fumes
Personal injury from improper lifting techniques or operating techniques
To protect yourself and others, make sure you thoroughly read and understand the
safety information presented in this manual before operating the machine.
