Hydraulic machine maintenance and safety operation procedures
Hydraulic oil, less than 20 degrees when the N32 / GB3141 is higher than 30 degrees, available N46 / GB3141.
Working oil recommended by the No. 32 and No. 46 antiwear hydraulic oil, use oil temperature 15 ~ 60 degrees.

2 after the oil industry is strictly filtered to join the fuel tank.
3 working oil is changed every year, and the first time should not be more than three months;
4 slide should always note lubricating oil, the appearance of the column should always keep clean, every time before work should be injected with oil.
5 under the nominal pressure 500T concentrated load maximum allowable eccentric 40mm. Eccentric too much easy to cause injury or other adverse phenomena.
6 check once every six months to check the pressure gauge;
7 more than a long period of time, the machine should be cleaned and coated with anti rust oil.
Safety operation procedures
1, do not understand the performance of the machine structure or operating procedures should not be allowed to start the machine;
2, the machine in the process of work, should not be carried out to repair and adjust the mold;
3, when the machine was found serious leakage or other abnormalities (such as action not dependable, noise, vibration, etc.) should stop analysis reason, try to rule out, not in spite of put into production.
4, shall not overload or exceed the maximum eccentric distance to use:
5, is strictly prohibited to exceed the maximum stroke of the slider, the mold is closed to a minimum height of not less than 600mm.
6, electrical equipment grounding must be firm and reliable:
7, the end of the day: the slider to the lowest position
