Tool Maintenance Guidelines
Daily Maintenance
Strictly adhere to all safety precautions during use
Keep valves and plunger assemblies clean, free from dust and oil contamination
Handle tools gently, avoid impacts and collisions
Ensure handles are fully tightened to prevent screw damage
Hydraulic System Care
Hydraulic Fluid Specification: YB-N32 or higher grade only
Prohibited Fluids: Alcohol, water, glycerol, brake fluid, ordinary engine oil
Filtration Requirement: 120-160 mesh filter for all hydraulic fluid
Connection Protection: Protect quick-connect ends from damage during disassembly
Storage & Long-Term Care
Store tools in original packaging when not in use
Maintain in dry, temperature-controlled environments
Apply anti-rust oil to jaw surfaces before storage
Regularly inspect hoses for aging; replace periodically
No-load operation strictly prohibited to prevent cylinder damage
Service Intervals
Tool Main Unit: Factory inspection and maintenance every 6 months
Jaws/Dies: Factory calibration and inspection after 20,000 cycles
Common Tool Faults & Solutions
| Symptom | Possible Cause | Solution |
| Insufficient or No Pressure | Low pressure valve adjustment | Check system pressure with gauge. If below 63MPa, tighten pressure valve screw to specified value |
| Damaged/lost elasticity in high-pressure valve spring | Replace high-pressure valve spring | |
| Mild wear on high-pressure valve seat | Repair valve seat: lightly tap grade-1 steel ball 1-2 times or re-drill with drill bit | |
| Mild wear on unloading valve seat | Same as above | |
| Worn oil pump plunger hole | Replace plunger, repair plunger hole | |
| Sudden Drop in Oil Delivery & Pressure During Use | Permanent deformation or breakage of high-pressure valve spring | Replace high-pressure valve spring |
| Permanent deformation or breakage of low-pressure valve spring | Replace low-pressure valve spring | |
| Oil contamination compromising check valve sealing | Disassemble pump, clean with gasoline/diesel, reassemble with clean oil | |
| Reduced Oil Delivery, Insufficient Low Pressure | Damaged/lost elasticity in low-pressure valve spring | Replace low-pressure valve spring |
| Mild wear on low-pressure valve seat | Repair valve seat using same method as above |
