To extend the usage cycle of an 8-meter-long spiral crawler pile driver, strict management of the fuel used by the rotary drilling rig is essential. The rotary drilling rig selects different types of fuel depending on the working environment. The fuel used by the rotary drilling rig should not contain impurities, as they can reduce the lifespan of the pile driver's engine. Additionally, the fuel tank should be cleaned regularly to prevent foreign objects from mixing in.

Management of engine oil, hydraulic oil, and gear oil: Do not mix oils of different grades and types. Use clean oil to avoid contamination with foreign materials (water, dust, particles, etc.). Choose oil grades based on environmental temperature and usage: in high temperatures, use oil with higher viscosity, and in lower temperatures, use oil with lower viscosity. Gear oil has a higher viscosity to accommodate higher transmission loads, while hydraulic oil has a lower viscosity to reduce resistance in fluid movement.

Lubricating grease reduces wear on moving surfaces. When storing lubricating grease, ensure it is not contaminated with dust, sand, water, or other impurities. When adding grease, try to squeeze out the old grease and clean the area thoroughly to prevent sand from adhering.

Maintenance of filter elements: Filter elements serve to filter impurities in the oil or air paths, preventing these impurities from entering components and causing failures. Use filter elements suitable for the machine. Various filter elements should be replaced regularly as per the operational maintenance manual. When changing filter elements, check for metal adherence on the old filter. If metal particles are found, clean them promptly.
