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 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.
