Yale GDP070 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system fault has been detected on the GDP070, such as severe engine or hydraulic issues. | Safely stop the forklift and investigate the fault before resuming work. | |
| Master Caution | AMBER | The GDP070 has identified a non-critical issue that needs attention soon, such as a minor sensor alert. | Review the display for details and address the caution at the next safe opportunity. | |
| Check Engine (MIL) | AMBER | The engine management system on your GDP070 has logged a fault that could affect performance. | Schedule service to diagnose and correct the engine issue. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below safe levels, risking severe engine damage on the GDP070. | Shut down the engine immediately and check oil level and possible leaks. | |
| Battery / Charging | RED | The alternator is not charging the battery, or battery voltage is critically low on the GDP070. | Inspect charging system and battery connections before continuing operation. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits, risking engine overheating on the GDP070. | Stop the forklift, allow the engine to cool, and check coolant levels. | |
| Transmission Temp | AMBER | The transmission fluid temperature is higher than normal, which can shorten component life on the GDP070. | Pause operation and allow the transmission to cool if safe. | |
| Brake System | RED | A fault has been detected in the GDP070's braking system, which may reduce stopping power. | Do not operate until brakes are inspected and repaired. | |
| ABS | AMBER | The anti-lock braking system is not functioning, so wheel lockup may occur during hard braking on the GDP070. | Drive cautiously and have the ABS checked soon. | |
| Parking Brake | RED | The parking brake is engaged or not fully released on the GDP070. | Release the parking brake fully before driving. | |
| Low Fuel | AMBER | Diesel fuel level is low, and the GDP070 will soon require refueling. | Plan to refuel at the next opportunity to avoid stalling. | |
| DPF / Regeneration | AMBER | The diesel particulate filter requires regeneration to burn off soot in the GDP070. | Follow the regeneration procedure as outlined in the operator's manual. | |
| DEF / AdBlue | AMBER | DEF (AdBlue) level is low, which is essential for emissions control on the GDP070. | Refill the DEF tank to maintain compliance and engine performance. | |
| Water in Fuel | AMBER | The fuel/water separator has detected water contamination in the diesel supply of the GDP070. | Drain the separator to prevent injector or engine damage. | |
| Hydraulic System | AMBER | A hydraulic system fault or low fluid level has been detected on the GDP070. | Check hydraulic fluid and inspect for leaks or system errors. | |
| Hydraulic Oil | AMBER | Hydraulic oil level is low or oil temperature is high in the GDP070. | Top up hydraulic oil and let the system cool if needed. | |
| Engine Oil Temperature | AMBER | Engine oil temperature is approaching unsafe levels in the GDP070. | Reduce load or idle to allow temperature to drop. | |
| Air Filter | AMBER | The air filter is clogged, restricting airflow to the GDP070's engine. | Inspect and replace the air filter as soon as possible. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter is restricted or water separator requires draining on the GDP070. | Replace the filter or drain water to maintain engine performance. | |
| Service / Hour Meter | AMBER | Scheduled maintenance interval has been reached on the GDP070. | Arrange for routine service to prevent wear or failures. | |
| Work Lights | BLUE | Work lights are switched on, improving visibility around the GDP070. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The safety beacon is illuminated to alert nearby personnel of the GDP070's operation. | Ensure beacon is functioning during operation in pedestrian areas. | |
| Overload / Capacity | RED | The GDP070 has detected a load exceeding its rated lifting capacity. | Lower the load immediately to prevent tip-over or equipment damage. | |
| Mast / Lift Limit | AMBER | The mast has reached its lift limit or a height warning is active on the GDP070. | Do not attempt to lift beyond this point; check load and mast settings. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Blocked oil filter
What to do
On the GDP070, immediately stop the engine and check oil level and for possible leaks. If oil level is normal, have the oil pump and filter inspected by a qualified technician before restarting.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Allow the GDP070 engine to cool, then check coolant level and radiator for obstructions. If coolant is low, refill with the correct type; otherwise, have the cooling system inspected.
Brake System
Common causes
- Worn brake pads or shoes
- Hydraulic leak
- Brake fluid loss
What to do
Do not operate the GDP070 until the braking system has been thoroughly checked and repaired. Inspect for leaks, worn components, and ensure fluid is at the correct level.
Overload / Capacity
Common causes
- Attempting to lift a load over the rated capacity
- Incorrect load distribution
- Faulty load sensor
What to do
Immediately lower the load and verify it is within the GDP070's rated limits. Redistribute the load if needed and have sensors checked if the warning persists.
Battery / Charging
Common causes
- Alternator failure
- Loose or corroded battery terminals
- Worn drive belt
What to do
Inspect the GDP070's battery connections, alternator, and drive belt for faults. Replace or repair any faulty components to restore proper charging.
Frequently Asked Questions
What should I do if the DPF regeneration light comes on in my GDP070?
Follow the regeneration instructions in the operator's manual; typically, you may need to keep the engine running at a certain RPM until the process completes.
Why does the DEF/AdBlue warning appear even though I recently filled the tank?
Check for proper DEF quality and ensure the cap is tightly sealed; sensor faults or contamination can also trigger this warning.
Can I keep operating the GDP070 if the air filter light is on?
It's best to replace or clean the air filter promptly to avoid reduced engine performance or increased fuel consumption.
How do I reset the service/hour meter reminder after maintenance on the GDP070?
After completing scheduled service, use the instrument panel buttons to navigate to the reset option as described in the operator's manual.
Is it safe to operate with the ABS light on?
You can operate, but braking performance may be reduced; avoid sudden stops and have the ABS checked soon.
