1. Antifreeze

To check whether the antifreeze has expired and needs to be replaced, the antifreeze is not only used in winter, but also can play a good role in avoiding boiling and descaling in summer.Genuine antifreeze can be used for 2000 hours, and general antifreeze can only be used. 1000 hours of use. Different brands of antifreeze are different, do not mix them.

2. Water tank, hydraulic oil radiator, air conditioner condenser

These places are easy to accumulate dead leaves, or the absorption of catkin fluff, which will hinder the heat dissipation of the water tank, hydraulic oil radiator and air conditioner condenser, which can easily cause high temperature of the engine, high temperature deterioration of hydraulic oil, and poor cooling of the air conditioner.

3. Grease

The ambient temperature in summer is high, the working temperature of the excavator will be higher, the high temperature will make the grease soft, the adhesion performance is reduced, and it is easy to be lost, causing the lubrication performance of the working device and the rotary device to decline or even fail.

4. Tire

During the summer driving of the wheeled excavator, there is a hidden safety hazard of the flat tire. Always check the braking performance of the whole machine and cool the tires. When the tire pressure and tire temperature are too high, the car should be parked in a cool place to cool down before continuing to drive. 

5, wading operations

In summer, there is a lot of rain. When wading, don't let the water exceed the center of the upper roller; when working in water, don't make the excavator tilt at an angle of more than 15° to avoid water in the upper structure; the crawler tensioning cylinder must also be loose and tight (Remove the sludge on the cylinder to prevent the cylinder from rusting).
