Maintenance and maintenance:
1 Working oil It is recommended to use No. 32 and No. 46 anti-wear hydraulic oil. The oil temperature should be within 15 to 60 degrees Celsius. 2. The fluid is allowed to enter the tank only after it has been strictly filtered. 3. The working fluid is changed once every year, and the first replacement time should not exceed three months; 4. The slider should always be lubricated. The appearance of the column should always be kept clean. Before each work, the engine oil should be injected. 5. Under the nominal pressure of 500T, the maximum allowable eccentricity is 40mm. If the eccentricity is too large, the column may be easily damaged or other undesirable phenomena may occur. 6. Check the pressure gauge every six months; 7. If the machine is to be decommissioned for a longer period of time, the surface of each additional area should be scrubbed and coated with anti-rust oil. II: Safe operation items 1. Those who do not understand the structure or performance of the machine should not start the machine without authorization. 2. The machine should not be overhauled and adjusted during the working process. 3. When the machine finds serious oil leakage or other abnormalities ( If the operation is not reliable, noise, vibration, etc.) should stop the analysis of the reasons, try to rule out, not sick into production: 4, shall not overload or exceed the maximum eccentricity to use: 5, is strictly prohibited more than the maximum stroke of the slider, the mold closed height The minimum must not be less than 600mm. 6, the grounding of electrical equipment must be solid and reliable: 7, the end of the work each day: the slider to the lowest position.
