Prolonged use of a high-speed guardrail pile driver can decrease the likelihood of the pile driver overheating, and in addition to routine operations according to the operating rules, it can also potentially cause damage to parts, but it also requires strict maintenance. If failures occur, they can be rectified in the following ways:

The first method involves setting the fuel pump to the neutral gear, lifting the upper piston, and allowing it to dry several times until the pile depth is within the normal range, and the pile driver can start normally. In winter, if the high-speed guardrail pile driver mistakenly uses summer diesel, the diesel wax will precipitate, blocking or clogging the oil passage and preventing the fuel pump from sucking oil normally. Therefore, it is necessary to choose different types of diesel according to the season. It should be noted that diesel hammers can only be used with diesel and not gasoline.

The second method of disassembly involves removing the fuel line of the fuel pump from the high-speed guardrail pile driver, draining the water until diesel completely flows out, and then draining the fuel pump. Remove the fixing screws on the lower cylinder body, set the fuel pump to neutral, lift the landing gear and upper piston, and let it dry several times to remove water from the cylinder, then reinstall the fixing screws.
