The Bobcat S130 skid-steer loader features a straightforward warning light system designed for quick diagnostics on the job site. Understanding these indicators helps prevent downtime and costly repairs, especially when working in tight spaces or with attachments.
Bobcat S130 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system fault is detected, such as low engine oil pressure or overheating, requiring immediate engine stop on the S130. | Shut off engine immediately and check the accompanying warning light. | |
| Master Caution | AMBER | A non-critical fault exists in the S130's systems, like a hydraulic oil level issue or air filter restriction, that needs attention soon. | Check the other indicator lights and refer to the operator’s manual. | |
| Check Engine (MIL) | AMBER | The engine control module on your S130 has detected a fault—possibly a sensor issue, fuel problem, or emission system malfunction. | Have the engine code read by a Bobcat dealer to diagnose the issue. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels in the S130, risking internal engine damage. | Stop engine immediately and check oil level and filter. | |
| Battery / Charging | RED | The alternator is not charging the battery or the charging system voltage is out of range on the S130. | Check battery connections and alternator belt; service if needed. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits in the S130, potentially causing overheating. | Stop engine and check coolant level, radiator fins, and fan belt. | |
| Hydraulic System | RED | A hydraulic system fault, such as low oil level or high temperature, is detected in the S130. | Check hydraulic oil level and temperature; let cool if hot. | |
| Parking Brake | AMBER | Indicates the parking brake is engaged on the S130, which is normal when starting, but should go off before moving. | Release parking brake before operating the machine. | |
| Seat Belt | AMBER | The seat belt is not fastened or the sensor detects an unbuckled occupant in the S130. | Fasten your seat belt to ensure safety and disable the warning. | |
| Glow Plug / Preheat | AMBER | The glow plugs are activated during cold start on the S130; wait for the light to turn off before cranking. | Wait for the indicator to go out, then start the engine. | |
| Low Fuel | AMBER | The S130's fuel level is low, and refueling is needed soon to avoid engine stalling. | Refuel with diesel as soon as possible. | |
| High Beam | BLUE | The high-beam headlights are activated on the S130 for better visibility in dark conditions. | No action needed; switch to low beams when approaching others. | |
| Work Lights | GREEN | The auxiliary work lights are switched on for improved illumination around the S130 at night or in dim areas. | Turn off when not needed to save battery. | |
| Hydraulic Oil | AMBER | The hydraulic oil level is low or the oil temperature is high in the S130, affecting performance of the loader arms and attachments. | Check hydraulic fluid level and top up if necessary; allow cooling if hot. | |
| Air Filter | AMBER | The engine air filter is restricted on the S130, reducing airflow and engine power. | Clean or replace the air filter according to the maintenance schedule. | |
| Fuel Filter / Water Separator | AMBER | Water has accumulated in the fuel filter/water separator or the filter needs replacement on the S130. | Drain water from the separator and replace fuel filter if needed. | |
| Service / Hour Meter | AMBER | The S130 has reached a scheduled maintenance interval based on engine hours, such as oil change or hydraulic filter replacement. | Perform the required service as listed in the operator’s manual. |

Most Important Warning Lights
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
On the Bobcat S130, check the oil level with the dipstick and top up with the correct SAE 10W-30 oil. If the light persists, inspect the oil filter and pressure relief valve.
Engine Overheating
Common causes
- Low coolant level
- Blocked radiator fins
- Faulty thermostat or water pump
What to do
For the S130, allow the engine to cool, then check the coolant reservoir. Clean debris from the radiator and ensure the fan belt is tight. Replace thermostat if needed.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Hydraulic oil overheating
- Contaminated oil or filter
What to do
On the Bobcat S130, check the hydraulic oil dipstick and refill with Bobcat hydraulic oil (ISO 46). Clean or replace the hydraulic filter and inspect for leaks.
Charging System Problem
Common causes
- Loose or corroded battery terminals
- Failed alternator
- Broken alternator belt
What to do
In the S130, clean and tighten the battery cables. Inspect the alternator belt tension and condition; replace if frayed. Test alternator output with a multimeter.
Engine Air Filter Restriction
Common causes
- Dusty operating environment
- Scheduled filter change overdue
- Filter damage or wetness
What to do
For the Bobcat S130, remove and inspect the air filter element. Tap gently to remove loose dirt or replace it if excessively dirty. Ensure the housing seals properly.
Frequently Asked Questions
What does the red stop light mean on my Bobcat S130?
The red master warning light indicates a serious fault that requires immediate engine shutdown, such as low oil pressure or overheating. Check the secondary indicator light to identify the specific problem.
Can I continue working with the amber caution light on?
An amber caution light on the S130 means a non-critical issue, like a service reminder or low fluid level. You can continue working, but schedule inspection soon to prevent escalation.
Why does my glow plug light stay on for a long time in winter?
In cold temperatures, the S130's glow plugs may preheat longer to ensure good starting. Wait until the light goes out, then crank the engine. If it stays on too long, the glow plug system may need checking.
How do I reset the service hour meter light?
The service light on the S130 resets after performing the scheduled maintenance. Typically, it requires a specific key sequence or a dealer visit using a diagnostic tool. Refer to your operator's manual for the exact procedure.
What should I do if the hydraulic light comes on while lifting a load?
If the hydraulic warning light activates on the S130, lower the load gently and stop the engine. Check the hydraulic oil level and look for leaks. If the oil is hot, let the machine cool before resuming work.
Is it okay to operate the S130 with the battery light on?
No, the battery light indicates the charging system is failing. The S130 will eventually lose electrical power and stall. Stop the machine and check belt tension, connections, and alternator function.
