What should I do if it is difficult to start the excavator in winter?

1. Use starting fluid on the excavator.

2. Bake the oil tank and the oil pan.

3. Use a fuel preheating device for the excavator.

4. When warming up the car in winter, cover the engine with a quilt or blanket to increase the starting speed by reducing heat loss and speeding up the heating process.

Nowadays, there are many manufacturers of fuel heating systems. The basic principle is to heat low-pressure oil circuits such as fuel tanks, fuel pipes, filters, etc., to remove the freezing and waxing phenomenon of diesel fuel and ensure the engine's stability. Normal fuel supply and optimized fuel spray quality make the engine burn more fully, and also have a good protective effect on the engine, thereby preventing the occurrence of difficulty in starting the excavator in winter.

5. When the ambient temperature drops, the battery's power loss also drops. If the battery's charge ratio is low, the battery electrolyte will freeze. Keep the battery charge close to 100 and insulate the battery from cold temperatures so the machine can be started easily the next morning.

Since the battery capacity will decrease significantly at low temperatures, wrap the battery, remove it from the machine, put it in a warm place, and then install it on the machine the next morning. If there are oxides on the electric column, just rinse it with boiling water. This can increase the battery life!

Excavator maintenance precautions:

Daily inspection work is an important link to ensure that the hydraulic excavator can maintain efficient operation for a long time, especially for For self-employed individuals, doing daily inspections can effectively reduce maintenance costs.

First, go around the machine twice to check whether there are any abnormalities in the appearance and the mechanical chassis, and whether there is grease flowing out of the slewing bearing. Then check the deceleration brake device and the bolt fasteners of the crawler track. Tighten what should be tightened. It should be replaced in time. If it is a wheeled excavator, you need to check whether there are any abnormalities in the tires and the stability of the air pressure.

Check whether the bucket teeth of the excavator are greatly worn. It is understood that the wear of the bucket teeth will greatly increase the resistance during the construction process, seriously affect the work efficiency, and increase the wear of equipment parts. Check the stick and cylinder for cracks or oil leakage. Check the battery electrolyte to avoid falling below the low level.

The air filter is an important component to prevent large amounts of dusty air from entering the excavator and should be checked and cleaned frequently. Always check the fuel, lubricating oil, hydraulic oil, coolant, etc. to see if they need to be added. It is best to select the oil according to the instructions and keep it clean.
