Master Warning (Stop)REDThis urgent red triangle means the E26 has detected a major system failure that could result in severe damage or unsafe operation.Immediately stop the excavator, shut down the engine, and investigate the cause before restarting.
Master CautionAMBERA general caution alert for the E26, signaling a non-critical system issue that needs attention soon.Check the display for specific warnings and address them at the next safe opportunity.
Check Engine (MIL)AMBERThe E26’s engine control module has detected a fault affecting emissions or performance.Review diagnostic codes and consult the service manual for troubleshooting steps.
Engine Oil PressureREDLow engine oil pressure detected, which can cause severe engine damage in the E26.Shut off the engine immediately and check the oil level and condition.
Battery / ChargingREDThe E26 is not charging its battery, possibly due to alternator or wiring issues.Inspect the alternator, battery terminals, and belt for faults before resuming operation.
Coolant TemperatureREDThe E26’s engine coolant temperature is dangerously high and could result in overheating.Stop operation, let the engine cool, and check coolant levels and radiator for blockages.
PParking BrakeREDThe parking brake is engaged on the E26, preventing movement.Release the parking brake before driving or operating the excavator.
Glow Plug / PreheatAMBERThe E26 is preheating the engine for cold starting using its glow plugs.Wait for the light to turn off before starting the engine in cold weather.
DPF / RegenerationAMBERThe E26’s diesel particulate filter requires regeneration to burn off soot.Follow the on-screen prompts to perform a parked or automatic regeneration cycle.
DEF / AdBlueAMBERDEF (AdBlue) level is low or there’s a system fault on the E26.Refill DEF tank or resolve system issue to avoid reduced engine power.
Water in FuelAMBERThe E26’s water separator has detected excess water in the fuel system.Drain water from the fuel separator to prevent injector or engine damage.
Low FuelAMBERThe E26’s fuel level is low and needs refilling soon to avoid stalling.Plan to refuel the excavator at the next opportunity.
Hydraulic SystemAMBERA hydraulic system alert on the E26 may indicate low fluid, filter restriction, or overheat.Check hydraulic fluid level and inspect for leaks or filter blockages.
Hydraulic OilAMBERHydraulic oil level or temperature is outside the safe range for the E26.Verify oil level and allow the machine to cool if overheated.
Air FilterAMBERThe E26’s air filter is clogged or restricted, affecting engine performance.Inspect and clean or replace the air filter as needed.
Fuel Filter / Water SeparatorAMBERThe E26 detects a clogged fuel filter or accumulated water in the separator.Replace the filter or drain the separator to ensure proper fuel flow.
Service / Hour MeterAMBERScheduled maintenance interval reached based on the E26’s operating hours.Perform required maintenance as specified in the E26 service schedule.
Work LightsBLUEThe E26’s work lights are switched on, improving visibility for the operator.Turn off work lights when not needed to conserve battery power.
Beacon / Rotating LightAMBERThe E26’s beacon light is active, signaling the excavator is in operation for job site safety.Deactivate the beacon when leaving the work area or transporting.
Swing / Slew LockAMBERThe swing lock is engaged on the E26, preventing the upper structure from rotating.Disengage swing lock before attempting to swing the house.
Overload / CapacityREDThe E26 is overloaded, risking tipping or structural damage.Reduce the load immediately and redistribute weight safely.
