Kobelco SK170LC-10 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | Illuminates when a critical fault is detected that requires immediate engine shutdown to prevent damage. | Stop the engine immediately and consult the fault code displayed on the monitor. | |
| Master Caution | AMBER | Lights up to alert the operator of a non-critical system issue that needs attention soon. | Check the monitor for detailed warning messages and schedule service. | |
| Check Engine (MIL) | AMBER | Indicates an engine management system fault, such as sensor or emission control issue. | Have the diagnostic codes read by a Kobelco dealer to identify the problem. | |
| Engine Oil Pressure | RED | Warns of low engine oil pressure, which can cause severe engine damage if ignored. | Immediately stop the engine and check oil level and pressure sender. | |
| Battery / Charging | RED | Shows when the alternator is not charging the battery or the charging voltage is out of range. | Check alternator belt and connections; if persists, service charging system. | |
| Coolant Temperature | RED | Indicates the engine coolant is overheating beyond safe operating limits. | Stop the engine, let it cool, and check coolant level and radiator for blockages. | |
| Hydraulic System | AMBER | Alerts to a hydraulic system issue such as low oil level or high temperature. | Check hydraulic oil level and temperature; inspect for leaks. | |
| Glow Plug / Preheat | AMBER | Illuminates when the glow plugs are activated for cold starting; stays on briefly. | Wait for the light to turn off before cranking the engine. | |
| DPF / Regeneration | AMBER | Indicates the diesel particulate filter is regenerating or needs a manual regeneration due to soot buildup. | Allow automatic regeneration to complete; if light stays on, perform parked regeneration as per manual. | |
| Low Fuel | AMBER | Warns that the fuel level is low and refueling is required soon. | Refuel with clean diesel to avoid air in the system. | |
| Air Filter | AMBER | Indicates the engine air filter is clogged and needs cleaning or replacement. | Clean or replace the air filter element to prevent power loss. | |
| Fuel Filter / Water Separator | AMBER | Signals water has accumulated in the fuel filter/water separator and needs draining. | Drain water from the separator and replace the fuel filter if necessary. | |
| Service / Hour Meter | AMBER | Reminds that scheduled maintenance is due based on engine operating hours. | Perform the required service as per the maintenance interval table in the operator's manual. | |
| Work Lights | GREEN | Indicates the work lights are turned on for improved visibility in low-light conditions. | No action needed; turn off when not required to preserve battery. | |
| Beacon / Rotating Light | GREEN | Shows the rotating beacon is active, alerting nearby personnel of machine operation. | Ensure beacon is on when operating in areas with pedestrian traffic. | |
| Swing / Slew Lock | AMBER | Illuminates when the swing lock is engaged to prevent upper structure rotation during transport or service. | Release the swing lock before operating the excavator to avoid damage. |

Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Clogged radiator fins
- Defective thermostat
What to do
Stop the engine immediately and allow it to cool. Check coolant level and refill if low. Clean radiator fins with compressed air. Replace thermostat if faulty. For the SK170LC-10, ensure the cooling fan clutch is engaging properly.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
Stop the engine right away. Check oil level via dipstick (SK170LC-10 uses 15W-40). If low, add oil to full mark. Replace oil filter if clogged. If light stays on, have oil pressure tested by a dealer.
Hydraulic System Overheat
Common causes
- Low hydraulic oil level
- Blocked hydraulic oil cooler
- Excessive load or continuous operation
What to do
Reduce load and allow the system to cool. Check hydraulic oil level and top up with Kobelco OEM oil. Clean the oil cooler core with low-pressure water. On the SK170LC-10, verify the cooling fan for the hydraulic oil cooler is running.
DPF Regeneration Required
Common causes
- Excessive idling
- Frequent low-load operation
- Soot accumulation
What to do
Perform automatic regeneration by running the engine at high idle (>1500 rpm) for about 20 minutes. If the light persists, initiate manual regeneration via the monitor menu. Refer to the SK170LC-10 operator's manual for specific regeneration procedure.
Frequently Asked Questions
What does the Master Warning (red) light mean on the Kobelco SK170LC-10?
It indicates a critical fault that requires immediate engine shutdown. Refer to the multi-function display for the specific error code; common issues include low oil pressure or coolant overheat.
How do I reset the service hour meter on my SK170LC-10?
The service reminder automatically resets after dealer maintenance. If you performed service yourself, access the monitor menu, select 'Maintenance' and set the hours to zero. Not all intervals can be reset by the operator.
Why is the amber hydraulic warning light on?
Possible causes: low hydraulic oil level, high oil temperature, or a clogged filter. Check the hydraulic oil sight glass on the tank and the temperature gauge. If the light stays on, inspect for leaks or contact service.
Can I operate the excavator with the swing lock light on?
No. The swing lock must be disengaged before operation. The light indicates the lock is engaged. Follow the release procedure near the operator's seat to avoid structural damage.
What should I do if the DPF regeneration light stays on continuously?
First, ensure the machine is in a well-ventilated area. Initiate a manual regeneration from the monitor menu. If it fails, the DPF may be clogged; contact a Kobelco dealer for cleaning or replacement.
How often should I replace the fuel filter on the SK170LC-10?
Kobelco recommends replacing the fuel filter every 500 hours or sooner if water-in-fuel light appears. Use only genuine Kobelco filters to ensure proper water separation.
