1. When welding the welding plate, first observe the arm, especially the welding plate in the front section, to see if there are screws or butter in the front section of the arm that affect the welding position. If there is, you can properly adjust the position of the welding plate, and you can weld a little backward. Ensure that the welding position and the beam body will not affect the structural parts on the paver after installation.

　　2. If the installation is inconvenient or cannot be installed due to product quality, it must be taken seriously, and it should be reported immediately. Inconvenient installation caused by incorrect screw hole size at the lower end of the rod. Encountering similar problems not only requires the accountability of the production and quality inspection departments, but also tests the on-site emergency handling capabilities of after-sales service personnel.

　　3. Now there are many paver arms that are orange-red, such as a certain model of Sany and DYNPAC, a summary record should be made during service, and self-painting of the correct color will be provided when shipping.

　　4. For new paver or temporarily trained operators who are not familiar with the position of the oil cylinder scale during normal construction, the elevation angle of the screed is generally about 10 degrees by lifting the oil cylinder, and the machine that is not fully preheated can be raised to 15 degrees.

　　5. Regarding the problem that the beam body is too heavy raised by the customer, it is necessary to explain that the weight of the beam body is related to the strength. If it is replaced with an aluminum alloy bracket, the structural strength cannot be guaranteed.

　　6. For the problem of uneven surface when starting, it may be caused by insufficient heating or uneven heating. It has nothing to do with the balance beam. You can start with the longitudinal slope sensor first, and then use the balance beam after the material is fully heated.
