After the user buys a new machine, don't think that it is a new machine that can be used without any random operation. Many people even think that the previous mistake will not affect the performance and life of the machine. This is very wrong. To ensure the performance of the machine and extend its service life, it must start from the "new".
After buying a new machine, before using the engine, you must first carefully read the instruction manual of the machine. The user should pay special attention to the basic requirements of the book:
First, the fuel with the specified grade should be fully precipitated and filtered before use, and the oiler should be kept clean.
Second, the lubricating oil should be kept clean, the amount of addition should be sufficient, and it should be replaced regularly. The use of the grade should be consistent with the regulations.
Third, the air filter should always pay attention to maintenance.
Fourth, pay attention to the addition of cooling water, especially not to make the engine work in the absence of water.
5. Always pay attention to the inspection and tighten the relevant bolts and nuts, especially the connecting rod bolts, the bolts on the drive shaft, the lock nut on the flywheel, and the fastening nut of the wheel. (early blue)
