Winter has arrived. With the temperature dropping, many projects are gradually slowing down. Like many machines, pile drivers used for installing guardrails are put on hold. So, how do you properly maintain a pile driver for installing guardrails during the winter? Below are the shared tips. First, clean the valve body surface of the pile driver used for installing guardrails, check for any looseness, tighten where it is narrow, lubricate where needed, and check if the antifreeze and engine oil levels are normal and if the oil quality is good. If it's normal, please add or replace in time; if the temperature is below zero or lower and the pile driver is parked outdoors for a long time, you must drain the engine coolant, and the pile driver battery must be removed and placed indoors or stored in a clean and insulated place to prevent temperature from getting too high and to avoid using battery power. Secondly, it's best to occasionally start the pile driver, preheat before starting the engine, then let it idle for a few minutes to check if parts are working normally, and stop the engine if the operation exceeds ten minutes; at the same time, start the air conditioning system to let the refrigerant circulate in the air conditioning system for a week. These maintenance tips are reflected in the instructions. Everyone should pay attention to daily maintenance. I also hope that the pile driver used for installing guardrails can survive the winter stably and provide you with better service when used next year.
