Oil-injected Vibratory Rammer

WACKER’s exclusive WM 80 engine features a unique patented oil-injection system that 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 rammer without oil for trouble-free operation..

Features & Benefits

• Powered by WACKER’s exclusive WM 80 engine, the only 2-cycle engine specifically designed and built for vibratory rammers and meets EPA and European air emission standards.
• Patent-pending vented carburetor evacuates air from the fuel line for easy starting.
• An integrated fuel valve and gas lever also provide for simple operation and easy starting by eliminating air in the fuel line.
• A unique three-stage air filtration system provides a virtually dust-free engine for longer life and improved durability.
• A filter minder tells the operator when the air filter needs to be changed.
• The guide handle offers a highly engineered, built-in shockmount system to reduce HAV (hand-arm vibration) and improve operator comfort.
• Automatic shutoff feature will shut down the unit if left idling for an extended period of time, reducing emissions and carbon build-up.
