What are the steps to replace L-HM 46 Hydraulic Oil

Here are the detailed steps for replacing L-HM 46 Hydraulic Oil:
1. Preparation
First, make sure the equipment is turned off and in a safe state, disconnect the power supply to prevent accidental startup. Prepare a clean drain container, funnel, filter, sufficient L-HM 46 Hydraulic Oil, and tools such as wrenches. At the same time, wear protective equipment such as protective gloves and goggles.
2. Draining the oil
Find the drain port of the hydraulic system, which is usually located at the bottom of the oil tank. Place the drain container under the drain port, slowly open the drain valve or screw plug, and let the old hydraulic oil slowly flow into the container. This process should be done carefully to avoid oil splashing. Remember to record the amount of oil drained, which will help determine the amount of new oil to add.
3. Cleaning system components
After draining the oil, remove the filter and other components on the oil tank. Wipe the inside of the oil tank with a clean cloth to remove residual sludge and impurities. If there is stubborn dirt inside the oil tank, it can be cleaned with a suitable detergent, but make sure the detergent is completely removed to avoid contaminating the new oil.
Clean the filter and other removable hydraulic components. Soak the filter in detergent to remove impurities, then rinse it with clean water, dry it, and put it back in place.
4. Add new oil
Before adding new oil, carefully check the quality of the new hydraulic oil to ensure that it meets the standards of L-HM 46 Hydraulic Oil and has no discoloration, turbidity or odor.
Slowly add new oil to the tank through a funnel with a filter. Pay attention to the oil level and add the appropriate amount of hydraulic oil according to the requirements of the equipment, not excessive.
5. Exhaust air
After adding new oil, start the hydraulic system and let it run at low speed. Operate the various actuators of the hydraulic equipment, such as the extension and contraction of the hydraulic cylinder and the rotation of the hydraulic motor, so that the hydraulic oil circulates in the system and exhausts the air in the system. In this process, pay attention to checking the oil level and adding new oil in time.
6. Check the system
Run the equipment for a period of time, check whether the pressure and temperature of the hydraulic system are normal, and check whether there are leaks in the pipes, joints and seals. If abnormalities are found, stop the machine in time for inspection and repair.
