Background:

The BS50-2I is a two-cycle vibratory rammer. Vibratory rammers, also known as tampers, jack rammers, or jumpers, are used in a variety of applications to flatten ground, including: construction, landscaping, home improvement, utility, and electrical work.

The Wacker Neuson BS50-2I rammer is intended to be used for compacting cohesive, mixed, and granular soils in confined areas. The BS50-2I 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. During proper use, the operator guides and controls the machine from behind using the handle.

It is important to wear gloves, Personal Protective Equipment(PPE) and to refer to the Wacker Neuson manual for instruction while using this device.
