What are the precautions to be taken during the use of a hydraulic shear

Here are the key precautions for using a Eagle hydraulic shear to ensure safety, operational accuracy, and equipment protection: 

1. Safety Operation Basics  
1. Personnel Qualification  
   - Operators must receive professional training, be familiar with equipment performance and hydraulic system principles, and strictly prohibit unlicensed operation.  
2. Work Environment Inspection  
   - Clear the cutting area of irrelevant personnel and flammable/explosive materials (e.g., gasoline, wood chips);  
   - Ensure the working surface is flat to prevent the shear from running out of control due to equipment tilting.  

2. Pre-Startup Preparations  
- Equipment Check：  
  - Inspect the blade for cracks or notches, and ensure connecting bolts are tight;  
  - Verify hydraulic oil level and temperature are normal (stop operation if oil temperature exceeds 60℃ for cooling).  
- Compatibility Confirmation：  
  - Match the shear model to the hardness of the material (e.g., using a small shear for thick steel plates will damage the blade).  

3. Key Operational Specifications  
1. Cutting Operation  
   - Material Fixation：Secure the material before cutting (e.g., clamp steel bars or plates firmly to prevent shaking and blade chipping);  
   - Blade Angle：Align the blade vertically with the cutting line, avoiding diagonal cuts or forced tearing (diagonal cuts accelerate blade wear);  
   - No Overloading：If cutting resistance suddenly increases (e.g., blade jams), stop immediately for inspection—never continue applying pressure.  
2. Equipment Linkage Notes  
   - When linked to an excavator or robotic arm, move slowly and smoothly to avoid hydraulic shocks damaging components due to abrupt stops or turns.  

4. Safety Protection Measures  
- Personal Protection：Operators must wear safety goggles and anti-slip gloves, keeping away from flying metal debris during cutting;  
- Warning Signs：Set up a cordon in the work area to prohibit non-operators from approaching.  

5. Post-Use Maintenance  
1. Immediate Cleaning  
   - Use high-pressure air to blow off metal debris and concrete residue between blades, preventing corrosion from residues;  
   - Wipe hydraulic pipe interfaces to prevent oil accumulation from attracting dust.  
2. Lubrication Maintenance  
   - Apply anti-wear grease to hinges and sliding parts to reduce mechanical wear;  
   - Check hydraulic oil for contamination and replace filters if necessary.  

6. Special Scenario Notes  
- High Temperature：Control continuous operation time in summer (stop for 10 minutes every 2 hours to cool);  
- Wet Environment：Dry the blade promptly after use to avoid rusting (apply anti-rust oil if needed).  

Summary：The core of standardized operation is "matching materials, stable cutting, and timely maintenance", which ensures work safety and prolongs equipment life. If abnormal blade wear or hydraulic leaks are found, stop operation immediately for repair.
