Yale GP050 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | This light illuminates if a major fault is detected in the GP050, such as severe engine or hydraulic failure. | Stop the forklift immediately and investigate the source of the warning. | |
| Check Engine (MIL) | AMBER | Signals that the engine management system has detected a fault specific to the GP050’s LPG or gasoline engine. | Schedule diagnostic service to identify and correct the engine issue. | |
| Engine Oil Pressure | RED | This warning means the engine oil pressure on the GP050 has dropped dangerously low. | Shut down the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | Indicates the alternator is not charging the battery while the GP050 is running. | Inspect the charging system and battery connections before resuming operation. | |
| Coolant Temperature | RED | The engine coolant temperature has exceeded safe limits for the GP050. | Turn off the engine and allow it to cool down before checking coolant level. | |
| Transmission Temp | AMBER | Warns that the transmission fluid temperature is higher than normal on the GP050. | Pause operation and let the transmission cool; check fluid if light persists. | |
| Brake System | RED | A fault has been detected in the GP050’s braking system, possibly low fluid or worn components. | Do not operate; inspect the brake system for leaks or wear. | |
| Parking Brake | RED | Shows that the parking brake is engaged while the GP050 ignition is on. | Release the parking brake before driving. | |
| Seat Belt | RED | Indicates the operator’s seat belt is not fastened while the GP050 is active. | Secure the seat belt before operating. | |
| Low Fuel | AMBER | The LPG or gasoline fuel level in the GP050 is nearing empty. | Refuel as soon as possible to prevent stalling. | |
| Hydraulic System | AMBER | Alerts to a hydraulic system issue, such as low fluid or pressure on the GP050. | Inspect fluid levels and look for leaks before further use. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or temperature is outside the normal range for the GP050. | Check hydraulic oil reservoir and top up if necessary. | |
| Air Filter | AMBER | Indicates the engine air filter on the GP050 is clogged or needs replacement. | Inspect and clean or replace the air filter. | |
| Fuel Filter / Water Separator | AMBER | Signals restriction or water in the GP050’s fuel filter. | Drain water or replace the filter as needed. | |
| Service / Hour Meter | AMBER | Reminds that scheduled maintenance is due based on the GP050’s operating hours. | Perform required service as indicated in the maintenance schedule. | |
| Work Lights | GREEN | Shows the GP050’s work lights are switched on for better visibility. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | Indicates the safety beacon is active on the GP050. | Ensure beacon is functioning for workplace safety. | |
| Overload / Capacity | RED | Warns that the GP050 is lifting a load above its rated capacity. | Lower the load immediately and check load weight. | |
| Mast / Lift Limit | AMBER | Indicates the mast has reached its maximum safe lift height on the GP050. | Do not attempt to lift higher; lower mast if necessary. | |
| Battery Discharge (BDI) | AMBER | Displays the discharge level of the GP050’s battery (if equipped with electric start). | Recharge or replace the battery if the indicator is low. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Blocked oil filter
What to do
For the GP050, immediately shut down the engine and check the oil level and condition. If the issue persists after topping up, have a technician inspect the oil pump and filter for faults.
Coolant Temperature
Common causes
- Low coolant
- Radiator blockage
- Faulty thermostat
What to do
If the coolant temperature warning activates on the GP050, stop operation and let the engine cool. Check coolant level and radiator for debris; if the problem continues, service the cooling system.
Brake System
Common causes
- Brake fluid leak
- Worn brake pads
- Hydraulic brake failure
What to do
Do not use the GP050 until the brake system is inspected for leaks, worn parts, or hydraulic faults. Address any issues before returning the forklift to service.
Overload / Capacity
Common causes
- Lifting load exceeding rated capacity
- Incorrect load distribution
- Faulty load sensor
What to do
Immediately lower the load on the GP050 and verify the weight is within rated limits. Inspect the load sensor if the warning persists with lighter loads.
Frequently Asked Questions
What should I do if the GP050's master warning light turns on?
Stop the forklift in a safe area, turn off the engine, and investigate for any critical faults or leaks before restarting.
How often should I check the hydraulic oil on the GP050?
Check the hydraulic oil level daily before operation and top up as needed to avoid system damage.
Why does the air filter light come on frequently?
Frequent illumination may indicate dusty operating conditions; inspect and clean or replace the air filter more often in such environments.
Can I keep working if the check engine light is on?
You can finish the current task if no other warnings appear, but schedule service soon to prevent engine damage.
What does the work lights indicator mean on the GP050?
It shows that the auxiliary work lights are switched on, improving visibility in low-light areas.
