The Bobcat Excavator E45 is a compact, powerful machine designed for demanding excavation tasks in tight spaces. Its instrument cluster provides key information and warnings to keep operators aware of the machine’s status and prevent costly downtime.
Bobcat Excavator E45 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system fault has been detected in your E45 that could cause severe damage if operation continues. | Shut down the excavator immediately and investigate the warning source. | |
| Master Caution | AMBER | A non-critical fault or maintenance issue has been detected by the E45’s monitoring systems. | Check the display panel for further details and address the issue soon. | |
| Check Engine (MIL) | AMBER | The E45’s engine control unit has logged a fault affecting engine performance or emissions. | Review fault codes and schedule service before continuing heavy use. | |
| Engine Oil Pressure | RED | Engine oil pressure has fallen below safe levels in your E45, risking severe engine damage. | Stop the engine immediately and check oil level and possible leaks. | |
| Battery / Charging | RED | The alternator is not charging the E45’s battery, or battery voltage is critically low. | Inspect the charging system and battery connections before restarting. | |
| Coolant Temperature | RED | Engine coolant temperature is excessively high, risking engine overheating in your E45. | Shut down and allow the engine to cool; check coolant level and radiator. | |
| Parking Brake | RED | The E45’s parking brake is engaged, preventing movement. | Release the parking brake before attempting to drive. | |
| Glow Plug / Preheat | AMBER | Glow plugs are warming the combustion chamber for cold starting the E45’s diesel engine. | Wait for the light to turn off before cranking the engine in cold conditions. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on your E45 needs to run a regeneration cycle to burn off soot. | Allow the regeneration process to complete without interruption. | |
| DEF / AdBlue | AMBER | DEF fluid level is low or there is a problem with the E45’s emissions system. | Refill the DEF tank and check for possible leaks or faults. | |
| Water in Fuel | AMBER | Water has been detected in the E45’s fuel filter, which can harm the injection system. | Drain the water separator promptly to avoid engine damage. | |
| Low Fuel | AMBER | The fuel tank on your E45 is nearly empty. | Refuel soon to avoid engine shutdown while working. | |
| Hydraulic System | AMBER | A fault or low pressure has been detected in the E45’s hydraulic system. | Inspect hydraulic fluid level and look for leaks or unusual noises. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or temperature is outside the normal range on the E45. | Check oil level and top up or investigate possible overheating. | |
| Fuel Filter / Water Separator | AMBER | The E45’s fuel filter is clogged or the water separator needs servicing. | Replace the filter or drain water as soon as possible. | |
| Service / Hour Meter | AMBER | Scheduled service is due based on the E45’s operating hours. | Arrange for routine maintenance to keep the excavator in peak condition. | |
| Work Lights | BLUE | The E45’s work lights are switched on for improved visibility. | No action needed unless lights are unintentionally left on. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active to alert others to the E45’s presence. | Use as required for site safety. | |
| Swing / Slew Lock | AMBER | The upper structure swing lock is engaged, restricting rotation of the E45. | Disengage the swing lock before rotating the upper frame. | |
| Overload / Capacity | RED | The E45 is overloaded or lifting beyond its rated capacity, risking instability. | Lower the load immediately and reassess lifting technique. | |
| Low Oil Level | AMBER | Engine oil level is below the recommended minimum for the E45. | Check and top up the engine oil before further use. | |
| Air Filter | AMBER | The air filter on your E45 is restricted or clogged, reducing engine performance. | Inspect and clean or replace the air filter. |

Most Important Warning Lights
Engine Oil Pressure Warning
Common causes
- Oil level too low
- Oil pump malfunction
- Oil filter blockage
What to do
Immediately stop the E45, check oil level and condition, and inspect for leaks or faulty pump before restarting.
Coolant Temperature Warning
Common causes
- Low coolant level
- Radiator blockage
- Failed thermostat
What to do
Let the engine cool, refill coolant if needed, and inspect the radiator and thermostat for issues specific to the E45.
Overload / Capacity Warning
Common causes
- Lifting load above rated capacity
- Incorrect load positioning
- Malfunctioning load sensors
What to do
Lower the attachment, reduce the load to within the E45’s limits, and check load monitoring systems for faults.
Battery / Charging Warning
Common causes
- Alternator failure
- Loose or corroded battery terminals
- Damaged battery
What to do
Inspect the E45’s alternator, clean battery connections, and test the battery for adequate charge.
DPF / Regeneration Warning
Common causes
- Interrupted regeneration cycles
- Excessive idling
- Faulty sensors in the DPF system
What to do
Allow the E45 to complete the DPF regeneration process and consult service if the warning persists.
Frequently Asked Questions
What should I do if the master warning light comes on during operation?
Stop the E45 immediately, check the display for specific fault details, and address the issue before resuming work.
Can I drive the E45 if the DPF regeneration light is on?
You can operate the machine, but it’s best to allow the regeneration cycle to finish to prevent filter blockage.
Why does the glow plug light stay on after starting?
If the glow plug light stays on, it could indicate a fault in the preheat system; have it checked if the light doesn’t turn off shortly after starting.
Is it safe to use the E45 if the hydraulic oil warning is displayed?
It’s not recommended; check oil levels and system condition before continuing to avoid hydraulic damage.
How often should I replace the air and fuel filters?
Follow the maintenance schedule in your E45’s manual, but replace filters more frequently in dusty or poor fuel conditions.
