Doosan Forklift G30P-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 major system of the G30P-5, requiring immediate attention. | Safely stop the forklift and investigate the warning source before resuming use. | |
| Master Caution | AMBER | A non-critical but important issue has been identified by the G30P-5's monitoring systems. | Check the instrument panel for additional warnings and resolve the issue soon. | |
| Check Engine (MIL) | AMBER | The engine control system has detected a malfunction specific to the G30P-5's LPG engine. | Schedule maintenance to diagnose and repair the engine fault. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels, risking severe engine damage. | Shut down the engine immediately and check oil level and condition. | |
| Battery / Charging | RED | The G30P-5's charging system is not supplying power to the battery. | Inspect the alternator, battery terminals, and drive belt before further operation. | |
| Coolant Temperature | RED | The engine coolant temperature has exceeded safe operating limits. | Stop the forklift, allow the engine to cool, and check coolant level and radiator. | |
| Brake System | RED | A major fault in the G30P-5's brake system has been detected, affecting stopping ability. | Do not operate the forklift until the brake issue is repaired. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on the G30P-5. | Release the parking brake before driving. | |
| Low Fuel | AMBER | The LPG fuel level is low and will soon be insufficient for operation. | Refuel the LPG tank promptly to avoid unexpected shutdown. | |
| Seat Belt | RED | The operator's seat belt is not fastened while the G30P-5 is in use. | Secure the seat belt before operating the forklift. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the G30P-5's accumulated operating hours. | Arrange for routine service to maintain reliability and safety. | |
| Work Lights | BLUE | The work lights are turned on to improve visibility around the G30P-5. | No action required unless lights are not functioning as expected. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active, signaling the forklift's presence to others. | Ensure the beacon is operational in busy or low-visibility areas. | |
| Overload / Capacity | RED | The load being lifted exceeds the rated capacity of the G30P-5. | Lower the load immediately and recheck the weight before attempting to lift. | |
| Hydraulic System | AMBER | A problem has been detected in the hydraulic system, possibly affecting lift or tilt functions. | Inspect hydraulic fluid level and check for leaks or unusual noises. | |
| Air Filter | AMBER | The air filter is clogged or requires replacement, reducing engine performance. | Clean or replace the air filter to restore proper airflow. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is restricted or contains excessive water, risking engine issues. | Drain or replace the fuel filter as soon as possible. | |
| Battery Discharge (BDI) | AMBER | The battery's state of charge is low, which may affect starting or electrical systems. | Recharge or replace the battery if low voltage persists. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum allowed lift height or a limit switch is activated. | Do not attempt to lift higher; lower the mast if necessary. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Blocked oil filter
What to do
Check the engine oil level and top up if needed; if the light remains on, do not restart the engine and have a technician inspect the lubrication system.
Overload / Capacity
Common causes
- Attempting to lift a load above rated capacity
- Incorrect load center
- Faulty load sensor
What to do
Lower the load immediately and confirm it is within the G30P-5's rated lifting capacity before resuming operation.
Brake System
Common causes
- Low brake fluid
- Worn brake pads or shoes
- Hydraulic brake leak
What to do
Inspect brake fluid level and check for visible leaks; do not operate the forklift until the braking system is fully repaired.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Allow the engine to cool, check coolant level, and inspect the radiator and thermostat for faults before restarting.
Frequently Asked Questions
What should I do if the Overload light comes on during lifting?
Immediately lower the load, verify the weight is within the G30P-5's rated capacity, and avoid lifting loads that exceed specifications.
Why does the Battery/Charging light stay on after starting?
This may indicate a problem with the alternator, drive belt, or battery connections; inspect these components before further use.
How often should I check the air filter indicator?
Monitor the air filter light daily, especially in dusty environments, and clean or replace the filter as soon as the warning appears.
What action is needed if the hydraulic system warning appears?
Check the hydraulic fluid level and inspect for leaks or abnormal noises before continuing operation.
Does the G30P-5 have a seat belt warning?
Yes, the seat belt indicator will illuminate if the operator is not buckled in, and the forklift should not be operated until the belt is fastened.
