The Bobcat E35 is a compact excavator designed for maneuverability and productivity in tight spaces, featuring an advanced instrument cluster for clear operational feedback. Understanding the E35's warning and indicator lights is essential to ensure machine longevity and operator safety.
Bobcat Excavator E35 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This signals a severe system fault detected by the E35’s monitoring system that could lead to major damage or unsafe operation. | Safely stop the excavator and investigate the source of the warning before proceeding. | |
| Master Caution | AMBER | The E35 has identified a non-critical issue that needs prompt attention to avoid escalation. | Review the display for more details and address the issue as soon as practical. | |
| Check Engine (MIL) | AMBER | The E35’s engine management system has found a problem affecting emissions or performance. | Inspect the engine and consult diagnostics to determine the cause. | |
| Engine Oil Pressure | RED | Oil pressure has dropped below safe levels in the E35’s engine, risking severe damage. | Shut down the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | The E35’s charging system is not maintaining battery voltage, risking electrical failure. | Inspect alternator, wiring, and battery connections before resuming work. | |
| Coolant Temperature | RED | Coolant temperature in the E35’s engine has exceeded safe operating range. | Stop the machine, allow it to cool, and check coolant level and radiator. | |
| Parking Brake | RED | The parking brake is engaged on the E35, preventing movement. | Release the parking brake before attempting to drive. | |
| Glow Plug / Preheat | AMBER | The E35 is preheating its glow plugs for cold starting. | Wait for the light to turn off before starting the engine. | |
| DPF / Regeneration | AMBER | The E35’s diesel particulate filter is actively regenerating to burn off soot. | Allow the regeneration process to complete without interruption. | |
| DEF / AdBlue | AMBER | DEF fluid level is low or there is a fault in the E35’s emissions system. | Refill DEF tank or troubleshoot the DEF system as indicated. | |
| Water in Fuel | AMBER | The E35’s water separator has detected excess water in the fuel system. | Drain the water separator to prevent injector damage. | |
| Low Fuel | AMBER | The E35’s fuel tank is nearing empty, risking engine shutdown. | Refuel at the next opportunity to avoid stalling. | |
| Hydraulic System | AMBER | A problem has been detected in the E35’s hydraulic system, such as low pressure or temperature. | Check hydraulic fluid level and inspect for leaks or overheating. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or condition in the E35 is below specification. | Top up or replace hydraulic oil as needed. | |
| Engine Oil Temperature | AMBER | Engine oil in the E35 is running hotter than normal, risking engine wear. | Pause operation and allow the engine to cool; check for cooling system issues. | |
| Air Filter | AMBER | The E35’s air filter is clogged, restricting airflow to the engine. | Clean or replace the air filter to restore performance. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter on the E35 is clogged or the water separator is full. | Replace the fuel filter and drain the separator. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the E35’s engine hours. | Perform required service as per the maintenance schedule. | |
| Work Lights | BLUE | The E35’s auxiliary work lights are switched on for improved visibility. | Turn off when additional lighting is no longer needed. | |
| Swing / Slew Lock | AMBER | The swing lock is engaged, preventing the E35’s upper structure from rotating. | Disengage the swing lock to allow normal rotation. | |
| Overload / Capacity | RED | The E35 has detected a load exceeding its rated lifting capacity. | Reduce the load immediately to prevent structural damage. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low oil level due to leaks or consumption
- Faulty oil pump
- Clogged oil filter
What to do
Stop the E35 immediately, check the engine oil level, and inspect for leaks or pump issues before restarting.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Failed cooling fan
What to do
Let the E35 cool down, then check coolant level and radiator for obstructions; repair the cooling fan if needed.
Overload / Capacity
Common causes
- Attempting to lift a load heavier than rated
- Incorrect load positioning
- Hydraulic malfunction
What to do
Lower the load promptly, verify the weight, and ensure the E35’s hydraulic system is functioning correctly before resuming lifting.
Battery / Charging
Common causes
- Faulty alternator
- Loose or corroded battery terminals
- Damaged wiring
What to do
Inspect the charging system components on the E35, clean terminals, and replace faulty parts as required.
Frequently Asked Questions
Why does the DPF regeneration light stay on during operation?
The E35 keeps the DPF regeneration active until soot levels are reduced; avoid interrupting the process to maintain emissions compliance.
What should I do if the water in fuel light appears?
Drain the E35’s water separator promptly to protect the fuel injectors and maintain engine performance.
How often should I change the hydraulic oil?
Follow the E35’s maintenance schedule, typically every 1000 hours or as indicated by the service light.
Can I operate the E35 with the swing lock engaged?
No, the upper structure will not rotate with the swing lock engaged; always disengage it before swinging.
What does it mean if the master warning light turns on but no other lights are illuminated?
The E35 may have detected a general system fault that isn’t assigned to a specific indicator; check the display for diagnostic messages.
