When we use the 4.2-meter refrigerated truck everyday, we will definitely follow certain requirements. After all, a few problems may affect our delivery of goods. Therefore, daily maintenance is still very important. But if we say that our refrigeration truck really has a malfunction, we must still handle it in a timely manner, and we must also know how to troubleshoot it. Once it is really difficult to handle it, it is best to be able to directly give all the work to the after-sales service personnel.

Normally, we usually use the 4.2-meter refrigerated trucks that have operating specifications. Although there are differences in the use of refrigerated trucks for each brand, the overall operation is certainly the same. However, if the refrigerated truck does not have the problem of cooling, it is best to be able to directly look at the type of the fault on the Internet. There are many corresponding methods of fault rectification on the network. If it is only a simple disassembly, you can know the cause of the fault. The driver can also Deal with it yourself. But if you can't rule out the failure, you must contact the manufacturer in time to see if you can go directly to the after-sales service shop.

As long as we purchase a regular 4.2-meter refrigerated truck brand vehicle, manufacturers will provide us with a good after-sales service, in advance we will explain what the contents of after-sales service are, there is a corresponding division of responsibilities. Because internal faults still require the dismantling of the machine, some of them may not be within the scope of protection. Once we have disassembled ourselves and have problems, it may be necessary to charge a lot of parts. It is best to be able to contact the merchant directly and let someone handle it. This will also protect our rights and interests.

The content of after-sales service must be determined in advance, the price of the 4.2-meter refrigerated car itself is not low, and the post-maintenance costs are also very high. Naturally, we must let the merchants provide us with more after-sales service projects. If there are a large number of vehicles for purchase, or if you plan to cooperate with each other for a long period of time, you can negotiate directly, enjoy certain preferential policies, guarantee discounts, and have a long after-sales service period, so that the vehicle has any problems. All can be handled in good time.


Industrial Laser Distance Sensor, we also call it secondary development laser distance module, which support TTL level and CMOS. The laser Range Sensor can be widely used in professional surveying, mapping, construction, robots, hunting arrows, industrial monitoring and automated measurement applications in electricity, transportation, etc. Our Laser Distance Module supports data communication with RS232, USB with a simple adapter. The results of laser Distance Sensor can be evaluated with Arduino. We are always looking ahead, hoping we can make every measurement simple in life!
