The excellent characteristics of the driving laser screed make its construction effect has been praised by people, and it meets people's needs. When using it, it is inevitable that there will be some malfunctions, so it needs to be repaired in time. During maintenance, there are often some misunderstandings. Today I will summarize it for you, and hope that you will not make similar mistakes again.


       1. The engine oil can only be added but not changed. When refueling the driving laser screed, many friends directly add fuel to it. In fact, this is not correct, because there are usually a lot of impurities remaining in the used motor oil. Even if it is completely exhausted, it is still There are impurities in the oil pan and oil circuit of Huicai. Therefore, when refueling, be sure to replace with new oil.


       2. New products are not available for selection. When replacing a new cylinder liner piston, you must look at the standard cylinder liner and piston size grouping and code. The replaced new cylinder liner and piston must be consistent with the previous size grouping code, so as to ensure the fit clearance Standards.


       3. The open flame directly heats the piston. Because the thickness of each part of the piston is inconsistent, if it is heated directly by an open flame, it will be inconsistent with the degree of thermal expansion and contraction, resulting in deformation. At the same time, when it is cooled at high temperature, the metal structure will be affected. Severe damage significantly reduces the wear resistance and reduces the service life of the driving laser leveler.

      When repairing the driving laser leveler, you must avoid the above misunderstandings. When replacing new devices, keep the type and specifications of the previous device consistent, and do not directly heat the piston. In addition, if you use gauze It is also incorrect to polish the bearing bush, which will affect the service life of the crankshaft.
