Iron Shearing Machine Troubleshooting
If an iron shearing machine stops suddenly, prioritize safety and follow this systematic troubleshooting guide.
⚠️ Immediate Safety Protocol
First action when machine stops: Turn off power immediately and wait for all moving parts to halt completely before inspection. Never reach into the machine while energized.
1 Power Supply Check
Verify electrical connections and power source integrity.
- Check if machine is securely plugged in
- Inspect power cord for damage or fraying
- Verify circuit breaker status (reset if tripped)
- Test outlet with another device if possible
Warning: Repeated circuit breaker trips indicate serious electrical issues - do not continue resetting. Contact an electrician immediately.
2 Hydraulic System Inspection
For hydraulic models, check fluid systems and components.
- Verify hydraulic oil level (check sight glass)
- Inspect for visible leaks around hoses/connections
- Check for air in the system (spongy controls)
- Examine pump operation sounds
3 Safety Features Verification
Inspect all protective devices and interlocks.
- Ensure emergency stop button isn't stuck
- Check for obstructions in blade path
- Verify overload protection hasn't activated
- Inspect safety curtain/door switches
4 Advanced Diagnostics
When basic checks don't resolve the issue.
- Consult machine manual for error codes
- Check motor capacitors for swelling
- Inspect drive belts for wear/tension
- Listen for unusual mechanical sounds
⚠️ Professional Assistance Required
For persistent problems: Contact a qualified technician to diagnose potential motor failure, gear jams, or control system faults. Never bypass safety systems to resume operation.
❌ Absolute Prohibitions
- Never force the machine to restart
- Never disable safety interlocks
- Never operate with known hydraulic leaks
- Never attempt repairs beyond your qualification
