Most Important Warning Lights
Engine Overheat
Common causes
- Low coolant level
- Radiator blocked with debris
- Faulty thermostat or water pump
What to do
On the SK260LC-11, stop the engine immediately, let it cool, then inspect and refill coolant per the operator's manual; clean the radiator fins with compressed air.
Low Engine Oil Pressure
Common causes
- Insufficient oil level
- Oil pump failure
- Clogged oil filter
What to do
Stop the engine on the SK260LC-11 right away, check the oil dipstick and add oil if low; if light persists, have the oil pump and filter inspected by a Kobelco technician.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Contaminated oil or clogged filter
- Hydraulic pump damage
What to do
For the SK260LC-11, reduce load and check the sight glass; add recommended hydraulic oil and replace filters; if no improvement, contact your Kobelco dealer for hydraulic pump testing.
Charging System Failure

Frequently Asked Questions
Why does the master warning light come on occasionally on my SK260LC-11?
It indicates a critical fault; check the monitor for a specific code. Common causes include low oil pressure or coolant overheat. Address immediately to avoid engine damage.
How do I perform a DPF regeneration on the SK260LC-11?
Park the machine on level ground, ensure no flammable materials nearby, then press the regeneration switch on the monitor. The engine will run at high idle to clean the filter; the process takes about 20 minutes.
What should I do if the check engine light flashes on my SK260LC-11?
The engine control unit has detected a malfunction. Reduce load and have the machine scanned by a Kobelco dealer. Do not continue heavy operation as it may lead to derate.
Why is the hydraulic caution light on after changing hydraulic oil?
Probably air trapped in the system after an oil change. Run the machine at low idle for a few minutes with the hydraulics cycled to purge air. If it stays on, check the oil level and filter condition.
How often should I replace the fuel filter on the SK260LC-11?
Kobelco recommends every 500 hours or annually. If the fuel filter warning light appears, replace it sooner to prevent injection pump damage.
Can I use any DEF fluid in the Kobelco SK260LC-11?
No, use only DEF that meets ISO 22241 standards. Contaminated or incorrect fluid can damage the SCR system and void warranty.
