These Wacker upright rammers are powered by a WM80 engine that features a unique patented oil-injection system - A unique patented oil injection system provides reliable performance by eliminating spark plug fouling and carbon buildup. The no mix system is an added convenience for operators. Plus an amazing
fuel to oil ratio of 120:1 allows for longer and cleaner running times....up to 65 hours on a single tank of oil. A low oil shutdown switch prevents running the tamper without oil for trouble free operation.

Patented vented carb evacuates air from the fuel line for easy starting. An integrated fuel valve and gas lever also provide for simple operation and easy starting of these Wacker tampers by eliminating air in the fuel line.

Powered by Wacker's exclusive WM 80 engine, the only 2-cycle

engine specifically designed and built for an oil injected jumping jack and meets EPA emissions standards

Automatic shutoff feature will shut down the Wacker BS50, BS60 or BS70 tamper if left idling for an extended period of time, reducing emissions and carbon build-up.

Rugged Wacker rammer designed for the compaction of cohesive, mixed and granular soils in confined areas
