Using the ATR 30 Rammer is a breeze. First, fill the 0.63 - liter fuel tank with petrol. Then, start the Honda GX 35 engine. You can choose the 130 - mm standard foot for normal jobs or the 80 - mm shoe for tight trenches. When operating, hold the open handle. It gives you a good view of the rammer foot and can be grabbed from all sides. Move the rammer at a speed of 12 m/min for effective compaction. Remember, the rammer can compact up to 30 cm deep and has a surface capacity of 94 m²/h. For maintenance, since the access to the engine and service points is easy, check the engine regularly and keep it clean. Also, make sure to refuel it in a well - ventilated area. If you notice any abnormal noises or performance issues, stop using it immediately and check for problems.
