Directly starting the excavator engine on a cold day without doing adequate inspections is also one of the wrong operations. You should first check whether the safety lock control lever is in a locked state; adjust the fuel control knob to the low speed position; keep the starting switch key in the preheating position; after the engine is started, if the oil pressure monitor indicator light is on, the travel pedals and joysticks cannot be operated.
2. Start the machine in a hurry without preheating
In order to be faster and simpler, many operators have wrong ways to start the excavator. For example, starting the engine in a hurry without preheating is also very harmful to the machine. It is necessary to master the correct preheating method and correctly start the excavator before starting it. The preheating operation check is: first press the preheating switch, start the engine after preheating for 10 seconds, wait until the engine runs smoothly, and check whether the instruments and indicator lights are normal, etc.
3. Don’t care about the insulation of the equipment
Who says excavators don’t need insulation in winter? You should take better care of your machine in winter. After you finish your work in winter, don’t forget to cover the engine of your excavator with an insulation curtain and sleeve. If necessary, use cardboard in front of the radiator to block the wind.
4. Ignore the excavator after shutting down
Don't think that you can put the excavator aside and ignore it after the work is done. This kind of thinking is very dangerous. After shutdown, the mud and water on the excavator body should be removed to prevent mud and dirt from entering the seal together with water droplets and damaging the seal. The location where the engine is parked is very important. It should be parked on hard, dry ground, and water accumulated in the fuel system should be drained to prevent freezing.
The above are just a few of the many maintenance points of the excavator. When using the excavator in winter, you must also not forget to perform daily maintenance such as buttering, fuel filters, and hydraulic systems to ensure the efficient operation of the excavator.
