In the process of using small rollers, the failures are actually unexpected, because we have not anticipated that, once the failure occurs, everyone will often be caught off guard and do not know how to deal with it. For example, if the small roller is in use The engine suddenly does not start during driving. Do you know the reason? In fact, when you are driving a small roller, if you do a good job in the run-in period, you can actually reduce the breakdown. To prevent the occurrence of small-sized roller failures, the operation should be regulated during the running-in period.

If there are some failures in the use of small rollers, it will cause delays in work. If the engine does not start. The possible reason is:

1. Check the control position to see if the fuel valve is open or not, and turn the valve to open. Close the choke door and turn on the engine switch of the compact roller.

2. Check the fuel. If the fuel is gone, add fuel. It may be that the fuel has deteriorated. In this case, it is necessary to change the fuel.

3. Remove and check the spark plug, clean, adjust the gap or replace the new spark plug. If the spark plug is soaked with fuel, dry it and reinstall it, and move the valve lever to a faster position.

No one can guarantee that their own small rollers will not malfunction, so the operators of ordinary small rollers must have a general understanding of the working principles of some related machinery in case of emergency. After leaving the factory, small rollers will normally have a running-in period of about 60 hours (some called the running-in period), which is stipulated by the manufacturing factory based on the technical characteristics of the initial use of construction machinery. The running-in period is an important link to ensure the normal operation of construction machinery, reduce the failure rate, and extend its service life.

But at present, some users neglect the extra skill request of the new machine during the running-in period because of the lack of common sense in the use of construction machinery or because of the tight schedule or want to obtain profits as soon as possible. Some users even think that, anyway, the manufacturer has a repair period, and the small roller is broken and the manufacturer is responsible for the repair, so the machine is overloaded for a long time during the running-in period, resulting in frequent early failures of the machine, which not only affects the normal application of the machine , Shortening the service life of the machine, and also because of the damage of the machine, affecting the progress of the project. Therefore, sufficient attention should be paid to the use and maintenance of the running-in period of small rollers.
