| Master Caution | AMBER | A non-critical system in your DX62R-3 requires attention; check the display for the specific warning. | Monitor the warning and schedule service at the earliest convenience. | |
| Check Engine (MIL) | AMBER | The engine control unit has logged a fault related to emissions or performance on your DX62R-3. | Have the engine diagnosed by a qualified technician soon. | |
| Engine Oil Pressure | RED | Engine oil pressure is below safe operating level for the DX62R-3; lack of lubrication can cause engine seizure. | Immediately shut off the engine and check oil level; do not restart until resolved. | |
| Battery / Charging | RED | The charging system on the DX62R-3 is not supplying adequate voltage; the battery may be discharging. | Check alternator belt and connections; if light persists, service the charging system. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits in the DX62R-3; overheating can cause engine damage. | Stop the engine and allow it to cool; inspect coolant level and radiator for blockages. | |
| Hydraulic Oil Temperature | AMBER | Hydraulic oil in the DX62R-3 is hotter than normal; extended operation may degrade system performance. | Reduce workload and allow the hydraulic system to cool; check oil level and cleanliness. | |
| Glow Plug / Preheat | AMBER | The preheat system is active to aid cold starting of the DX62R-3 engine. | Wait for the light to turn off before cranking the engine. | |
| Water in Fuel | AMBER | Water has been detected in the fuel system of your DX62R-3, which could damage the injection system. | Drain the water separator or replace the fuel filter as soon as possible. | |
| Low Fuel | AMBER | The fuel level in the DX62R-3 is low; the machine may run out of fuel if not refueled soon. | Refuel the machine promptly to avoid air in the fuel system. | |
| Parking Brake | RED | The parking brake on the DX62R-3 is engaged; release before moving. | Release the parking brake switch before operating the machine. | |
| Seat Belt Indicator | RED | The operator's seat belt on the DX62R-3 is not fastened; safety regulations require it to be worn. | Fasten the seat belt before operating the machine. | |
| Work Lights | BLUE | The work lights on the DX62R-3 are turned on, improving visibility in low-light conditions. | No action needed; the light indicates the work lights are active. | |
| Beacon / Rotating Light | GREEN | The safety beacon on the DX62R-3 is operating, alerting others that the machine is active. | Ensure the beacon is functional when operating in areas with other personnel. | |
| Swing / Slew Lock | AMBER | The swing lock on the DX62R-3 is engaged, preventing the upper structure from rotating. | Disengage the swing lock before slewing the excavator. | |
| Service / Hour Meter | GREEN | This indicator shows the accumulated operating hours of the DX62R-3; it may flash when scheduled maintenance is due. | Perform the recommended service at the specified hour interval. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat or fan
What to do
For the DX62R-3, first check the coolant level in the recovery tank and inspect the radiator for debris; if the issue persists, inspect the fan belt and thermostat, and flush the cooling system.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Worn engine bearings
What to do
On the DX62R-3, immediately check the engine oil dipstick and refill if low; if the light stays on, have a technician test oil pressure and inspect the pump.
Charging System Failure
Common causes
- Loose or broken alternator belt
- Faulty alternator
- Battery terminal corrosion
What to do
For the DX62R-3, examine the alternator belt tension and condition; clean battery terminals and check connections; if the light remains, the alternator may need replacement.
Hydraulic Overheat
Common causes
- Low hydraulic oil level
- Contaminated or degraded oil
- Overloaded operation
What to do
On the DX62R-3, allow the hydraulic system to cool, then check the oil level and condition; if dirty, change the oil and filter; avoid prolonged heavy loads.
Water in Fuel System
Common causes
- Contaminated fuel
- Failed water separator
- Condensation in fuel tank
What to do
In the DX62R-3, drain water from the fuel filter/water separator assembly; if the light repeats, replace the fuel filter and ensure fuel is sourced from a clean supply.
Frequently Asked Questions
Why does the master warning light come on and the engine shuts down instantly?
This typically indicates a critical condition such as low oil pressure or engine overheat. On the DX62R-3, the ECU may initiate an automatic shutdown to prevent catastrophic damage. Check the display for the specific cause and follow the recommended action.
What should I do if the preheat light stays on for a long time?
On the DX62R-3, the glow plug indicator should turn off after a few seconds in warm weather. If it stays on, there may be a fault in the preheat system; have the glow plugs and relay checked by a dealer.
Can I operate the excavator with the hydraulic oil temperature light on?
It is not recommended. On the DX62R-3, the amber light warns that hydraulic oil is hot; continued operation can degrade seals and performance. Reduce load and allow the system to cool before resuming normal work.
How often should I service the DX62R-3 based on the hour meter?
The DX62R-3 follows a scheduled maintenance interval typically at 50, 250, 500, and 1000 hours. The hour meter light may flash at service due times; refer to the operator's manual for the exact tasks required.
What does the water in fuel light mean and how do I fix it?
This light indicates that water has separated from fuel in the system. On the DX62R-3, locate the water separator on the fuel filter housing (usually near the engine). Turn the drain valve to expel water until clean fuel appears, then tighten. If the light persists, replace the fuel filter.
Why is my swing lock light blinking even though I disengaged the lever?
The swing lock on the DX62R-3 may have a sensor issue or the lock mechanism is not fully released. Check the swing lock lever is fully in the disengaged position; if the light remains, inspect the sensor or contact a technician.
