| Master Caution | AMBER | A non-critical fault has been detected; check the central display for specific warnings on your SK140SRLC-7. | Monitor the central display and address the indicated issue at the next service opportunity. | |
| Check Engine (MIL) | AMBER | The engine management system has identified a fault affecting emissions or performance on your SK140SRLC-7. | Have the engine diagnosed by a Kobelco dealer to prevent further issues. | |
| Engine Oil Pressure | RED | Engine oil pressure is dangerously low, risking severe engine damage on your SK140SRLC-7's turbocharged diesel engine. | Stop the engine immediately and check oil level; if full, call for service. | |
| Battery / Charging | RED | The charging system is not functioning correctly, and the battery may not be charged on your SK140SRLC-7. | Check alternator belt and connections; if light persists, service the charging system. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits, which can cause engine damage on your SK140SRLC-7. | Stop the engine allow it to cool; check coolant level and radiator for blockages. | |
| Hydraulic System Warning | RED | A fault in the hydraulic system has been detected, potentially affecting performance or safety on your SK140SRLC-7. | Stop work and inspect hydraulic fluid level and filters; if light remains, contact service. | |
| Hydraulic Oil Level | RED | Hydraulic oil level is low, which can cause cavitation and damage to pumps and cylinders on your SK140SRLC-7. | Top up hydraulic fluid to the correct level using Kobelco-approved oil. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is higher than normal, possibly due to heavy load or low oil level on your SK140SRLC-7. | Reduce engine load and check oil level; if light stays on, have the cooling system inspected. | |
| Air Filter Restriction | AMBER | The engine air filter is clogged and needs replacement to maintain proper airflow on your SK140SRLC-7. | Replace the air filter according to the maintenance schedule. | |
| Fuel Filter / Water Separator | AMBER | Water has accumulated in the fuel filter/water separator, which can damage the fuel system on your SK140SRLC-7. | Drain the water from the fuel filter bowl immediately. | |
| Water in Fuel | AMBER | Excess water detected in the fuel system; this can cause injection issues on your SK140SRLC-7. | Drain water separator and check for fuel contamination. | |
| Low Fuel | AMBER | Fuel level in the tank is low and needs refueling soon for your SK140SRLC-7. | Refuel with clean diesel to avoid air in the system. | |
| Glow Plug / Preheat | AMBER | The glow plugs are preheating the engine for cold start on your SK140SRLC-7. | Wait for the light to turn off before cranking the engine. | |
| DPF Regeneration | AMBER | The Diesel Particulate Filter needs regeneration to clear accumulated soot on your SK140SRLC-7. | If flashing, perform parked regeneration as per operator's manual; if steady, continue working. | |
| DEF / AdBlue Level | AMBER | The Diesel Exhaust Fluid level is low and needs replenishment for emissions compliance on your SK140SRLC-7. | Refill DEF tank with approved fluid before it runs out. | |
| Service / Hour Meter | AMBER | The scheduled maintenance interval is approaching or overdue on your SK140SRLC-7. | Perform the required service as per the maintenance schedule. | |
| Work Lights | GREEN | The work lights are turned on for improved visibility on your SK140SRLC-7. | No action needed; indicates lights are active. | |
| Beacon / Rotating Light | GREEN | The rotating beacon is active, indicating the machine is in operation on your SK140SRLC-7. | Ensure beacon is used for safety in work areas. | |
| Swing / Slew Lock | AMBER | The swing brake is engaged, preventing the upper structure from rotating on your SK140SRLC-7. | Release swing lock before operating, unless machine is parked. | |
| Door Open | AMBER | The cab door is not fully closed, which may expose you to noise or debris on your SK140SRLC-7. | Close the door securely before operating. | |
| Seat Belt | RED | The seat belt is not fastened; for safety, always wear it while operating your SK140SRLC-7. | Fasten your seat belt immediately. | |
| Overload / Capacity Warning | RED | The load on the excavator exceeds safe working limits, risking tip-over or structural damage on your SK140SRLC-7. | Reduce load immediately and reposition machine if necessary. | |
| High Exhaust Temp (HEST) | AMBER | Exhaust temperature is high during DPF regeneration; avoid parking near flammables on your SK140SRLC-7. | Continue operation normally; if light persists, check for regeneration issues. |

Most Important Warning Lights
Low Hydraulic Oil Level
Common causes
- Hydraulic fluid leak
- Aged seals
- Infrequent level checks
What to do
Top up with Kobelco genuine hydraulic oil (ISO VG 46) and inspect lines and cylinders for leaks on your SK140SRLC-7.
DPF Regeneration Failure
Common causes
- Low exhaust temperature due to light load
- Soot overload
- Faulty sensors
What to do
Perform a parked regeneration via the monitor panel; if unsuccessful, contact your Kobelco dealer for forced regeneration.
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins
- Malfunctioning fan clutch
What to do
Allow engine to cool, then check coolant level and clean radiator core; if problem persists, inspect cooling system components.
Fuel System Contamination
Common causes
- Water in fuel
- Dirty fuel filters
- Microbial growth
What to do
Drain water separator and replace fuel filters; use clean diesel and add biocide if needed on your SK140SRLC-7.
Electrical System Fault
Common causes
- Loose battery connections
- Failed alternator
- Corroded wiring harness
What to do
Check battery terminals and alternator belt tension; if warning persists, have the electrical system diagnosed by a Kobelco technician.
Frequently Asked Questions
How do I perform a parked regeneration on my SK140SRLC-7?
Park the machine on level ground, engage the parking brake, and allow the engine to idle. Press the DPF regeneration switch on the monitor panel; the process takes about 20 minutes. Do not interrupt the cycle.
What type of hydraulic oil does the SK140SRLC-7 require?
The SK140SRLC-7 uses Kobelco genuine hydraulic oil ISO VG 46 or equivalent. Always check the operator's manual for approved alternatives.
Why is my swing lock warning light on?
The swing lock is engaged when the machine is parked or the swing brake is manually applied. Release the swing lock lever or switch before slewing.
How often should I replace fuel filters?
Replace fuel filters every 500 hours or as indicated by the service interval. Also drain water from the separator daily.
What does the master caution light mean?
It alerts you to a non-critical issue; check the central display for specific codes. Common causes include low DEF level or air filter restriction on your SK140SRLC-7.
Can I operate with the DPF regeneration light flashing?
No, a flashing DPF light indicates regeneration is needed and should be performed immediately to avoid filter clogging and power loss.
