With the arrival of the winter solstice, many areas in the north ushered in the icy days of ice and snow, so-called autumn trousers, leather pants, down jackets, it is time to put them out!

Here, John Deere also wants to remind the vast number of excavators and loader users, not just to keep warm, but ignore the maintenance of the love machine, you know, these steel behemoths are not "cold and cold" They are also afraid of "frozen"!

Excavators should pay attention to "antifreeze" in winter

So how do you operate and maintain the equipment during the cold winter? Please keep in mind the following points -

Point one: start

In the winter, equipment such as excavators often encounter troubles when starting up, and it is prone to failure to catch fire. The following points can be effectively avoided:

1. Select a battery with a cold start current and try to keep the battery fully charged.

2. Choose the right diesel, for example, in the environment of minus ten degrees, choose -35 diesel, otherwise the diesel will wax and lose fluidity. The same is true for the choice of oil, and the oil should be changed in time according to the actual temperature.

3. In an extremely cold environment (below 30 degrees below zero), it is necessary to install a cold start assist device in advance, such as the John Deere excavator option "burning diesel coolant heater", which can effectively solve the problem of ultra-low temperature. The difficulty of starting is difficult.

Avoid the following two operations when starting up difficult:

The raw fire heats the engine block. Even if you keep a certain distance, it won't work. Because there are a lot of exposed pipes on the excavator, the leaking oil will inevitably stick to these pipes. In case of high temperature open flame, there is a hidden danger of fire and burning equipment.

Release the coolant and heat it up before pouring it back. In this case, if the temperature of the heated coolant is too high and the machine temperature is too low, a large temperature difference may cause partial cracking of the cylinder, and such damage is difficult to repair. If you have to do this, be sure to control the temperature.

Key point 2: warm up

Not only do people need to warm up before the exercise, but the excavator is the same. After starting, there must be a warm-up phase, that is, before the engine water temperature and hydraulic oil temperature rise to 50 degrees, first idle for a period of time, then slow and slightly operate, let the equipment smoothly and smoothly enter the state, then Start normal operation again.

In addition, the winter construction site is prone to snow and ice, so try to avoid excessive movement during operation to avoid the danger of slipping.

Point three: maintenance

Excavator maintenance, the most common is to change the oil. In the winter, the engine must be preheated before changing the engine oil. Otherwise, the oil will be very sticky under cooling and will not be cleaned, and the dirt and other dirt deposited on the bottom of the tank will not be easily taken out.

Point 4: Storage

In the winter, if the excavator is not used for a long time, it is necessary to do a good job in cold protection. If conditions permit, the equipment engine can be covered with thermal insulation curtains such as insulation curtains or thermal insulation sleeves. If necessary, park the equipment in the garage and block the cold wind with cardboard in front of the radiator to protect the equipment.

Check the freezing point of the coolant used, and if necessary, empty the coolant in the engine to prevent freezing and freezing in the body, causing the body to burst and cause equipment damage.

If it is not used for a long time, the battery should be removed and stored indoors.

Finally, John Deere reminds everyone again that winter construction is safe first! In a harsh construction environment, work safety must be kept in mind. Only when you are safe, making money makes sense! You said yes?
