1. In the use of pile drivers, the maintenance and management of equipment is particularly important. Warming up the machine before using it is often seen as a cumbersome and time-consuming step by many, who believe it to be unnecessary and think the machine can be used without it. However, warming up is essential.

2. It's crucial to strictly adhere to the maintenance regulations for pile drivers, diligently perform maintenance at all levels, and ensure that the pile driver is always in good condition. Attention should also be paid to its reasonable use and correct operation. Before working, the voltage of the power supply should be checked to ensure it meets the requirements. The insulation of cables and wires should be inspected for integrity, and the controller's contacts and limits should be checked for correctness.

3. The reason for warming up before use is that when the pile driver starts working, it is in a cold state. Suddenly introducing hot oil, which expands with heat and contracts with cold, can cause significant damage to oil seals. Coupled with the high frequency of motion, it is more likely to lead to oil leaks and frequent replacement of oil seals.
