Maintenance and Care Suggestions
Proper maintenance and care of industrial components can extend their service life, reduce downtime, and ensure optimal performance. Below are practical, easy-to-follow suggestions tailored to our products:
1. Routine Inspection (Weekly)
Check all hydraulic connectors (56529 series, 56519 series) for leaks, loose fittings, or corrosion, and tighten as needed. Inspect solenoid valves (127908-D2) for proper operation, ensuring they respond quickly to signals. Check filter elements (30170016-E/30156633-1) for clogging—if the pressure differential exceeds 0.5MPa, replace the element immediately. Test fasteners (50103-16-B, 50006-6-C5D) for loosening, and retighten using the specified torque. Inspect cable ties (117121-500, 53300-525) for damage, and replace any broken or degraded ties.
2. Regular Maintenance (Monthly)
Lubricate clevis pins (111944) and cylinder rods (122023/122024) with high-temperature lithium grease to reduce friction. Clean hydraulic connectors and apply a thin layer of anti-seize compound to the threads, ensuring easy disassembly. Replace lock washers (50906-C/50910-C) if signs of wear or deformation are found. Inspect counterbalance cylinders (122023/122024) for leaks, rod scoring, or excessive movement, and replace seals if needed. Clean sun cartridge covers (99838-1) and check for damage.
3. Long-Term Storage & Special Care
Store all components in a dry, ventilated warehouse with a temperature of 10℃ to 30℃ and relative humidity ≤ 60%. Hydraulic connectors (56529 series) and valves (127908-D2) should be stored with O-rings coated in hydraulic oil to prevent drying and cracking. Fasteners should be coated with anti-rust oil and stored in sealed containers to prevent corrosion. Filter elements (30170016-E/30156633-1) should be stored in sealed packaging to prevent contamination. Counterbalance cylinders (122023/122024) should be stored with the rod fully retracted and filled with hydraulic oil to prevent corrosion.

On-Site Fault Maintenance Cases
Below are 3 real on-site fault cases and their practical solutions, helping users quickly resolve common technical issues, reduce downtime, and make the most of our products:
Case 1: Solenoid Valve (127908-D2) Malfunction and Fluid Control Failure
Fault Phenomenon: An automation facility reported that the SOLENOID VALVE, ATOS 127908-D2 was malfunctioning, failing to control hydraulic fluid flow, which disrupted the production line. Solution: Inspect the valve and find that the solenoid coil was burned out due to voltage fluctuation. Replace the solenoid valve with a new 127908-D2, check the voltage supply (ensure it matches 24VDC), and install a surge protector to prevent future voltage damage. After replacement, the valve operated correctly, and fluid control was restored. Cause Analysis: Voltage surge damaged the solenoid coil. Suggestion: Install surge protectors for solenoid valves and check voltage supply regularly.
Case 2: Hydraulic Connector (56529-6-6-S) Leak and Pressure Loss
Fault Phenomenon: A construction company reported that a CONNECTOR, O-RING BOSS/37° 56529-6-6-S was leaking hydraulic fluid, leading to pressure loss in the counterbalance cylinder (122023). Solution: Inspect the connector and find that the O-ring was worn and cracked. Replace the O-ring and the connector (if damaged), clean the threads, and torque the connector to the specified value (35 N·m). After repair, the leak stopped, and system pressure was restored. Cause Analysis: O-ring wear due to prolonged use and exposure to high pressure. Suggestion: Inspect O-rings in connectors monthly and replace them every 12 months.
Case 3: Filter Element (30170016-E) Clogging and System Efficiency Drop
Fault Phenomenon: A manufacturing plant reported that the HYDRAULIC FILTER ELEMENT 30170016-E was clogged, causing a drop in hydraulic system efficiency and increased pressure differential. Solution: Replace the filter element with a new 30170016-E, flush the filter housing to remove debris, and check the hydraulic fluid for contamination. After replacement, the system pressure differential returned to normal (≤0.3MPa), and efficiency was restored. Cause Analysis: Contaminants in the hydraulic fluid clogged the filter media. Suggestion: Replace filter elements every 6 months or when the pressure differential exceeds 0.5MPa, and use clean hydraulic fluid.
