The Kubota skid steer loader, such as the SVL65-2 or SVL75-2, uses a comprehensive instrument cluster to keep you informed of machine status and potential issues. Indicators are color-coded: red for immediate action, amber for caution, and green/blue for normal functions.
Kubota skid steer Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This red stop light illuminates when a critical fault is detected, such as low engine oil pressure or high coolant temperature, requiring immediate engine shutdown on your Kubota skid steer. | Stop the machine safely, shut off the engine, and consult the operator's manual for the specific fault code. | |
| Check Engine (MIL) | AMBER | This amber light signals an engine management issue; on Kubota V3800 engines, it may indicate a sensor fault or emission control problem. | Have the diagnostic trouble codes read by a Kubota dealer as soon as possible. | |
| Engine Oil Pressure | RED | When this red light turns on, engine oil pressure is below safe levels, which could damage the Kubota's 4-cylinder diesel engine. | Immediately stop the engine, check oil level, and inspect for leaks. | |
| Battery / Charging | RED | This red light indicates an alternator or battery charging fault on your Kubota skid steer, often caused by a loose belt or failed alternator. | Check battery connections and alternator belt; if persistent, have the charging system tested. | |
| Coolant Temperature | RED | The red coolant light warns of engine overheating; for Kubota skid steers, this may occur during heavy digging or in dusty conditions. | Stop the machine, let the engine idle to cool, and check coolant level and radiator for debris. | |
| Hydraulic Oil | AMBER | This amber light indicates low hydraulic oil level or high temperature in the Kubota hydraulic system, affecting loader and auxiliary functions. | Check hydraulic oil level and temperature; if low, add Kubota UDT fluid as specified. | |
| Parking Brake | AMBER | This amber light reminds you that the parking brake is engaged on your Kubota skid steer, which must be released before machine operation. | Release the parking brake lever before moving the machine. | |
| Seat Belt | AMBER | The seat belt indicator illuminates when the operator is not buckled; on Kubota skid steers, the machine may not allow hydraulic functions until fastened. | Fasten your seat belt securely before starting operation. | |
| Glow Plug / Preheat | AMBER | This amber preheat light stays on while the glow plugs warm the Kubota diesel engine's combustion chambers in cold weather. | Wait for the light to turn off before cranking the engine. | |
| Low Fuel | AMBER | This amber light indicates low fuel level in the Kubota's tank, typically when less than 10% remains. | Refuel with clean diesel fuel as soon as possible. | |
| High Beam | BLUE | This blue light shows that the high-beam headlights are activated on your Kubota skid steer for improved visibility. | Use low beams when other equipment or personnel are nearby. | |
| Hydraulic System | RED | A red hydraulic system warning indicates a serious fault, like a failed pump or low pressure, on Kubota's load-sensing hydraulics. | Stop the machine immediately and contact a Kubota service technician. | |
| Fasten Seat Belt | AMBER | This amber light with a seat icon reminds the operator to buckle up; on Kubota skid steers, the safety interlock may disable functions. | Fasten your seat belt before operating. | |
| Air Filter | AMBER | This light signals a clogged engine air filter on Kubota skid steers, reducing airflow and engine performance. | Inspect and replace the air filter element if dirty. | |
| Service / Hour Meter | AMBER | When the scheduled maintenance interval is reached, this light flashes to remind you of upcoming service on your Kubota skid steer. | Perform the required maintenance per the owner's manual schedule. | |
| Work Lights | GREEN | This green indicator shows that the auxiliary work lights are turned on for nighttime operation. | No action needed; use lights as required for safe visibility. | |
| Beacon / Rotating Light | GREEN | When the beacon is activated, this green light indicates the safety light is operating to alert others of the machine. | Ensure beacon is used in high-traffic areas. | |
| Overload / Capacity | RED | This red warning indicates the lift arms or bucket are overloaded beyond the rated capacity of your Kubota skid steer. | Reduce the load immediately to avoid tip-over or structural damage. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator fins
- Failed water pump
What to do
Stop the machine and let the engine cool. Check coolant level and add Kubota long-life coolant if low. Clean the radiator core with compressed air. If issue persists, inspect the water pump and thermostat.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Contaminated hydraulic fluid
- Failed hydraulic pump
What to do
Check hydraulic oil level and top up with Kubota UDT fluid. If oil appears milky or dark, replace the filters and fluid. A failed pump requires professional replacement by a Kubota dealer.
Engine Won't Start
Common causes
- Battery discharged
- Fuel system air or water
- Faulty glow plugs (cold weather)
What to do
Check battery voltage (12V minimum) and clean terminals. If the preheat light stays on, wait or replace glow plugs. Bleed air from the fuel system using the primer pump on Kubota engines.
Loader Lift Arm Not Responding
Common causes
- Safety interlock (seat belt not fastened)
- Low hydraulic pressure
- Fuse blown on control module
What to do
Verify seat belt is fastened and the parking brake is released. Check hydraulic fluid level. Inspect fuses in the cab relay box; replace if blown.
Frequently Asked Questions
What does the flashing amber light on my Kubota skid steer dash mean?
A flashing amber light usually indicates a service reminder for the hour meter (e.g., every 50 hours for engine oil change). Press the hour meter button to reset after service.
Why does my check engine light stay on after starting?
This likely indicates a sensor fault or emission issue. Kubota skid steers use a diagnostic system; have the codes read by a dealer. It may be a one-time glitch, but if persistent, avoid heavy operation.
Can I operate the machine with the hydraulic oil warning light on?
No. That amber light warns of low oil or high temperature. Continuing could damage the hydraulic pump. Stop and check fluid level; if hot, let the system cool.
How do I reset the glow plug light if it stays on too long?
The glow plug light should turn off after a few seconds. If it stays on, the glow plug relay or controller may be faulty. Have it inspected; do not crank the engine excessively.
What should I do if the master warning light comes on?
Stop the machine immediately. This red light indicates a critical fault like low oil pressure or high coolant temp. Shut off the engine and consult the manual for the fault code displayed on the dash.
Is it safe to drive with the parking brake light on?
No. The parking brake light on Kubota skid steers also indicates a brake system fault if it stays on when released. Check the brake fluid level and linkage; do not operate until resolved.
