3. Doosan DX215-9C excavator has superior performance, super power, and mature technology to easily cope with multiple harsh working conditions.
Work Tips:
1. When the weather cools down in winter, the power of the battery will also be affected. Therefore, if it is an old battery, it is easy to lose power too quickly. In this case, replace it with a new power supply as soon as possible to avoid finding out that there is no battery when starting up. power situation. In addition, when the north enters the winter off-season, the excavator may also be parked for too long, resulting in the loss of battery power. In this case, the battery can be disassembled in advance, stored indoors, and then installed in advance when it is necessary to start work.
2. In addition to power loss, fuel is the biggest factor affecting engine starting in winter. It is recommended to use winter antifreeze fuel according to the lowest local temperature. If you want to stop and park for a long time, try to park in a sheltered and sunny place as much as possible. Fill up the fuel tank, let it rest for about an hour, open the water outlet at the bottom, and release the excess water mixed in the diesel oil, which can avoid the situation that the water in the diesel oil is analyzed and freezes the fuel oil circuit. Start the engine at regular intervals to check whether the antifreeze and engine oil are sufficient.
3. After entering the winter, due to the drop in temperature, the normal or slight leaks and wear failures that were originally used in summer will become much more serious. For example, the increase in the plunger clearance in the diesel pump, the change in the valve clearance, the increase in the gap between the piston ring and the cylinder liner, and many other dimensional changes are not conducive to starting the engine in winter. Therefore, it is necessary to do a good job of warming up before starting the excavator.
4. As the temperature drops, the viscosity of the engine oil increases, and the resistance between the moving parts increases, which leads to a decrease in the number of revolutions when the engine starts, and also increases the wear of the engine piston rings, cylinder liners, and crankshaft connecting rods. In winter, it is necessary to replace the winter type engine oil in time to reduce the wear and load when the engine starts.
