The Yale GDP060 is a diesel-powered forklift designed for medium-duty industrial applications. Its instrument cluster provides operators with essential alerts and system information specific to safe and efficient forklift operation.
Yale GDP060 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical malfunction has been detected in the Yale GDP060 that could cause severe damage or unsafe operation. | Safely stop the forklift immediately and investigate the root cause before restarting. | |
| Check Engine (MIL) | AMBER | The engine management system has identified a fault specific to the GDP060's diesel engine controls. | Schedule service as soon as possible and avoid heavy loads until inspected. | |
| Engine Oil Pressure | RED | Engine oil pressure has dropped below the safe range for the GDP060 and continued operation could lead to engine failure. | Shut down the engine immediately and check oil level and leaks. | |
| Battery / Charging | RED | The alternator on the GDP060 is not charging the battery, risking electrical system shutdown. | Inspect the charging system and drive to service if possible. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded safe limits for the GDP060, risking overheating. | Stop the forklift and allow the engine to cool before checking coolant level. | |
| Transmission Temp | AMBER | Transmission fluid temperature is running hot, which can affect shifting and longevity on the GDP060. | Reduce workload and allow the transmission to cool; check fluid level if issue persists. | |
| Brake System | RED | A brake system malfunction has been detected, reducing stopping ability on the GDP060. | Do not operate until the brakes are inspected and repaired. | |
| Parking Brake | RED | The parking brake is engaged, preventing movement of the GDP060. | Release the parking brake before driving. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on the GDP060 requires regeneration to prevent clogging. | Perform a parked regeneration cycle as soon as possible. | |
| DEF / AdBlue | AMBER | DEF fluid level is low, which will eventually limit engine power on the GDP060. | Refill the DEF tank at the next opportunity. | |
| Water in Fuel | AMBER | Water has been detected in the fuel system, risking injector or pump damage on the GDP060. | Drain the water separator before further operation. | |
| Low Fuel | AMBER | Diesel fuel level is approaching empty in the GDP060's tank. | Refuel as soon as possible to avoid stalling. | |
| Hydraulic System | AMBER | A hydraulic system fault has been detected, possibly affecting lift or tilt functions on the GDP060. | Inspect hydraulic fluid and seek service if performance is affected. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or pressure is below normal for the GDP060, risking sluggish operation. | Top off hydraulic oil and check for leaks. | |
| Air Filter | AMBER | The engine air filter is clogged, which can reduce power and efficiency on the GDP060. | Replace or clean the air filter at the next maintenance interval. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is restricted or water is present, affecting engine operation on the GDP060. | Replace the fuel filter and drain separator promptly. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours for the GDP060. | Arrange for routine service as indicated. | |
| Work Lights | GREEN | Work lights are switched on, illuminating the GDP060's work area. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The safety beacon is active, alerting others to the GDP060's presence. | No action required unless beacon operation is not needed. | |
| Overload / Capacity | RED | The load on the GDP060 exceeds rated lifting capacity, risking tip-over or damage. | Lower the load and verify weight before continuing. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Blocked oil filter
What to do
Immediately shut off the GDP060 engine and check oil level and condition; do not restart until the issue is resolved and oil pressure returns to normal.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Stop the engine, allow it to cool, and inspect the coolant system for leaks or blockages before refilling and restarting.
Brake System
Common causes
- Worn brake pads
- Hydraulic leak
- Brake fluid loss
What to do
Do not operate the GDP060 until the brake system has been inspected and all components are repaired or replaced as needed.
Overload / Capacity
Common causes
- Attempting to lift a load above rated capacity
- Incorrect load positioning
- Malfunctioning load sensor
What to do
Lower the load immediately, confirm the weight is within the GDP060's limits, and inspect for sensor issues if the warning persists.
Battery / Charging
Common causes
- Broken alternator belt
- Alternator failure
- Loose battery connections
What to do
Check the alternator belt and battery terminals; if the issue remains, arrange for electrical system service before further use.
Frequently Asked Questions
What should I do if the DPF regeneration light comes on during operation?
If possible, complete the current task and then park the GDP060 in a safe location to perform a regeneration cycle as instructed in the operator manual.
How often should I check the hydraulic oil level?
For the GDP060, inspect hydraulic oil daily before startup and top off as needed to prevent system faults.
Is it safe to operate with the check engine light on?
While the GDP060 may still run, continued use with the check engine light on can worsen faults; schedule service promptly.
Why does the overload light come on even with a light load?
This may indicate a malfunctioning load sensor or incorrect mast positioning; have the system inspected by a qualified technician.
Can I drive the GDP060 with the parking brake light on?
No, always release the parking brake before moving to avoid brake wear or system damage.
