Using the Ammann ATR 68 P Rammer is straightforward. First, make sure the fuel tank is filled with petrol. Adjust the handle height according to your size for maximum comfort. To start the engine, set the gas throttle lever to the '1 - Idle speed' position and start the engine. Then, move the lever to '2 - Full speed' for normal operation. When you're done, set the lever to the '0 - Stop position' to cut off the fuel and shut down the electric system. When using the rammer, always maintain a firm grip on the handle to ensure precise control. Be aware that the compaction performance may vary depending on ground conditions. For maintenance, regularly check the air filters. The double air filtration system helps, but it's still important to clean or replace the filters as needed. Keep an eye on the engine oil level and change it as recommended by the manufacturer. Also, check the machine for any signs of wear or damage after each use, especially the foot and handle parts.
