Fuel-saving tips for small pile drivers involve the essential use of hydraulic oil. High-quality hydraulic oil can fully enhance the performance of the pile driver and reduce fuel consumption. Here is how to save on fuel consumption when using a small pile driver. During use, ensure the pressure range is consistent and not too high; this can not only reduce fuel consumption but also protect related components and improve work efficiency. Choosing the appropriate drill bit based on different construction conditions can effectively lower fuel consumption during the drilling process. Before lifting the drill bit of the small pile driver, properly reversing the drill bit at the last moment uses the oil well, not only improving the performance of the pile driver but also reducing fuel consumption. The viscosity of the hydraulic oil should be moderate, with the oil's viscosity temperature index not being less than 90. After applying the above four points, good hydraulic oil should have excellent antioxidation and hydrolytic stability. By understanding and combining with practical operations, we believe at least 20% of fuel can be saved. Saving fuel means saving money, and the usage time of the small pile driver can be extended.
