Doosan Forklift G25E-5 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault has been detected in a vital system of the G25E-5, such as engine or hydraulics. | Safely stop and turn off the forklift immediately; inspect for faults before restarting. | |
| Check Engine (MIL) | AMBER | The engine control unit has logged a malfunction that could affect performance or emissions. | Schedule service and avoid heavy loads until the issue is diagnosed. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped dangerously low, risking severe engine damage. | Shut off the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | The alternator is not charging the battery, or battery voltage is critically low. | Stop operation and inspect battery terminals and alternator connections. | |
| Coolant Temperature | RED | The engine coolant temperature has exceeded safe limits for the G25E-5. | Turn off the engine and allow it to cool; check coolant level and radiator. | |
| Transmission Temp | AMBER | The transmission fluid is running hotter than normal, which may impact shifting. | Pause operation and check fluid levels; let the system cool if needed. | |
| Brake System | RED | A fault in the G25E-5's brake system has been detected, reducing braking effectiveness. | Stop the forklift and inspect brake fluid and components before resuming work. | |
| Parking Brake | RED | The parking brake is engaged while the ignition is on or the forklift is in gear. | Release the parking brake fully before moving the forklift. | |
| Seat Belt | AMBER | The operator's seat belt is not fastened while the ignition is on. | Buckle the seat belt before operating the forklift. | |
| Low Fuel | AMBER | The LPG fuel level is low and the G25E-5 will soon require refueling. | Plan to refill the LPG tank at the next opportunity. | |
| Hydraulic System | AMBER | A problem has been detected in the hydraulic system, such as low fluid or pressure. | Check hydraulic fluid level and inspect for leaks before continuing. | |
| Service / Hour Meter | AMBER | The forklift is due for scheduled maintenance based on operating hours. | Arrange for maintenance as soon as possible to keep the G25E-5 in optimal condition. | |
| Work Lights | GREEN | The forklift's work lights are switched on for improved visibility. | No action needed; turn off when extra lighting is no longer required. | |
| Beacon / Rotating Light | AMBER | The beacon light is active, signaling the forklift's presence for safety. | No action required unless beacon is not functioning when needed. | |
| Overload / Capacity | RED | The load exceeds the rated capacity of the G25E-5, risking tip-over or damage. | Lower the load immediately and reduce weight to within safe limits. |

Most Important Warning Lights
Engine oil pressure warning
Common causes
- Low engine oil level
- Oil pump failure
- Oil filter blockage
What to do
Check and top up engine oil level, inspect for leaks, and replace the oil filter if clogged. If the warning persists, do not operate the G25E-5 and contact Doosan service.
Coolant temperature warning
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Allow the engine to cool, refill coolant if needed, and inspect the radiator for obstructions. If overheating continues, arrange for professional inspection.
Brake system warning
Common causes
- Low brake fluid
- Worn brake pads
- Hydraulic brake leak
What to do
Inspect and top up brake fluid, check for leaks and pad wear. Do not use the forklift until brakes are fully functional.
Overload/capacity warning
Common causes
- Load exceeds rated fork capacity
- Incorrect load positioning
- Attachment adds extra weight
What to do
Immediately reduce the load to within the G25E-5's rated limits and adjust positioning. Avoid using non-approved attachments.
Battery/charging warning
Common causes
- Alternator failure
- Loose battery terminals
- Aged battery
What to do
Check battery connections, test the alternator output, and replace the battery if it cannot hold a charge.
Frequently Asked Questions
What should I do if the master warning light comes on while operating the G25E-5?
Stop the forklift immediately in a safe area, turn off the engine, and investigate the source of the warning before restarting.
How often should I service the Doosan G25E-5 based on the hour meter light?
Follow the Doosan maintenance schedule, typically every 250 hours, or as indicated by the hour meter light.
Can I continue working if the hydraulic system light is amber?
You may continue briefly, but check fluid levels and inspect for leaks as soon as possible to prevent damage.
Why does the overload warning activate even when the load seems light?
Incorrect load positioning or attachments can trigger the overload sensor; always center the load and avoid unapproved attachments.
What does it mean if the seat belt light is on but I am buckled in?
Check the seat belt switch for proper connection or damage, as it may need adjustment or repair.
