The Yale GLC060 is a reliable LPG-powered forklift, commonly used for medium-duty material handling in warehouses and distribution centers. Its instrument cluster features a concise set of warning and indicator lights designed to keep operators informed about critical systems and maintenance needs.
Yale GLC060 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system fault has been detected on your GLC060 that could damage the forklift or endanger safety. | Safely stop the forklift and arrange for immediate inspection by a qualified technician. | |
| Master Caution | AMBER | A non-critical issue or system alert is present, requiring attention soon to prevent further problems. | Check the display or service menu for more details and plan maintenance at the next opportunity. | |
| Check Engine (MIL) | AMBER | The engine management system has detected a fault specific to the GLC060's LPG powertrain. | Schedule service to diagnose the engine control system and avoid extended operation until resolved. | |
| 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 leaks before restarting. | |
| Battery / Charging | RED | The alternator is not charging the battery, which may leave the forklift unable to start. | Inspect the alternator belt, battery connections, and charging system as soon as possible. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded the safe range for the GLC060. | Stop operation, allow the engine to cool, and inspect coolant levels and radiator. | |
| Transmission Temp | AMBER | Transmission fluid is running hotter than recommended, which can affect shifting and component life. | Reduce load and allow the transmission to cool; check fluid level and cooling system. | |
| Brake System | RED | A malfunction has been detected in the GLC060's brake system, reducing braking performance. | Do not operate until the brake system is inspected and repaired. | |
| Parking Brake | RED | The parking brake is engaged, which will prevent normal driving. | Release the parking brake before attempting to move. | |
| Seat Belt | AMBER | The operator seat belt is not fastened, compromising safety during operation. | Fasten the seat belt before using the forklift. | |
| Low Fuel | AMBER | The LPG fuel tank is nearly empty, risking engine shutdown. | Refuel the LPG tank at the next opportunity. | |
| Hydraulic System | AMBER | A problem has been detected in the hydraulic system, affecting lift or tilt operations. | Inspect hydraulic fluid level and check for visible leaks. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on engine hours logged on your GLC060. | Arrange for routine service as recommended in the maintenance schedule. | |
| Work Lights | BLUE | The work lights are switched on to improve visibility around the forklift. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | The overhead warning beacon is active to alert others of forklift movement. | No action needed; ensure beacon remains operational for safety. | |
| Overload / Capacity | RED | The load on the forks exceeds the rated lifting capacity of the GLC060. | Lower the load immediately and reduce weight to within safe limits. | |
| Air Filter | AMBER | The engine air filter is restricted, reducing engine performance and efficiency. | Inspect and clean or replace the air filter element. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter is clogged or water has been detected in the separator. | Drain water and replace the fuel filter to prevent engine issues. | |
| Hydraulic Oil | AMBER | Hydraulic oil level is low or oil quality is poor, risking system performance. | Top up hydraulic oil and check for contamination or leaks. |

Most Important Warning Lights
Engine Oil Pressure
Common causes
- Low engine oil level
- Oil pump failure
- Oil filter blockage
What to do
Stop the GLC060 immediately, check oil level and add oil if low; if the warning persists, have a technician inspect the oil system before restarting.
Coolant Temperature
Common causes
- Low coolant level
- Radiator blockage
- Failed thermostat or water pump
What to do
Allow the forklift to cool, check coolant level, and inspect for leaks or blockages; avoid operation until the cause is resolved.
Brake System
Common causes
- Brake fluid leak
- Worn brake pads or shoes
- Hydraulic brake failure
What to do
Do not use the GLC060 until the brake system is fully inspected and any faults are repaired to ensure safe stopping.
Overload / Capacity
Common causes
- Load exceeds rated capacity
- Incorrect load center
- Attachment weight not considered
What to do
Lower the forks, reduce the load to within the GLC060's rated limits, and verify load center and attachment weights before resuming operation.
Battery / Charging
Common causes
- Alternator failure
- Loose or corroded battery cables
- Damaged wiring
What to do
Inspect the charging system, tighten or clean battery connections, and replace faulty components to restore normal charging.
Frequently Asked Questions
What should I do if the Check Engine light comes on but the forklift runs normally?
Continue to operate with caution, but schedule service soon—minor faults can become serious if ignored on the GLC060.
How often should I check the hydraulic oil on the Yale GLC060?
Check the hydraulic oil level daily before each shift to prevent system damage and maintain smooth lift operation.
Why does the Overload light activate even with a moderate load?
The load center or attachment weight may be affecting capacity; verify load placement and consult the capacity chart on your GLC060.
Is it safe to operate with the Master Caution light on?
You can finish the current task, but investigate the cause and schedule maintenance promptly to avoid escalation.
What does the hour meter service light mean?
It signals that scheduled maintenance is due based on engine hours; follow the maintenance interval to keep your GLC060 reliable.
