Small excavator is an important construction machinery and equipment, is widely used in construction, mining and agriculture and other fields. Small excavator has a complex mechanical structure and use of the environment, so in the use of the process is very easy to maintenance failure, which suddenly no action is more common, the reasons are probably the following.
1. Power system failure

1. check the hydraulic pump to see if it works properly
2. check the hydraulic motor to see if it can work properly to work
3. check the hydraulic cylinder to see if there is oil leakage phenomenon or other damages
