How to use four-meter shearing machine and four-meter bending machine
First, the filter
1. The filter should be replaced or thoroughly cleaned each time the oil is changed.
2. The air filter on the fuel tank is inspected and cleaned every 3 months, preferably 1 year.
3. Other abnormality of the filter should be replaced if the machine has related alarms or oil quality is not clean.
Second, hydraulic components
1. Clean hydraulic components (substrate, valve, motor, pump, oil pipe, etc.) every month to prevent dirt from entering the system and not to use detergent.
2. After using the new machine for one month, check whether there is any deformation at the bend of each tubing. If there is any abnormality, it should be replaced. After two months of use, the joint of all fittings should be tightened. Shut down when doing this work, the system has no pressure.
Third, the hydraulic oil circuit
1. Check the oil level of the fuel tank every week. If the hydraulic system is repaired, check it. The oil level should be filled with hydraulic oil below the oil window.
2. The system oil temperature should be between 35 °C and 60 °C, and should not exceed 70 °C. If it is too high, it will cause deterioration of oil quality and accessories.
3. The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25.
4. After the new machine is working for 2000 hours, the oil should be changed. After every 4000 to 6000 hours of operation, the oil should be changed. The oil tank should be cleaned every time the oil is changed.
