| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical malfunction has been detected by the G25N-7’s system, requiring the forklift to be stopped immediately. | Cease operation and investigate the source of the warning before restarting. | |
| Check Engine (MIL) | AMBER | The engine management system has found a problem affecting emissions or performance in the G25N-7. | Schedule service promptly and avoid heavy loads until checked. | |
| Engine Oil Pressure | RED | Engine oil pressure is dangerously low, risking severe engine damage in your G25N-7. | Shut down the engine and check oil level and leaks immediately. | |
| Battery / Charging | RED | The alternator is not charging the battery, risking a stall or non-start in the G25N-7. | Inspect the charging system and avoid shutting off the engine until resolved. | |
| Coolant Temperature | RED | Coolant temperature has exceeded safe limits, threatening engine overheating in the G25N-7. | Stop the forklift, let the engine cool, and check coolant levels. | |
| Brake System | RED | A fault in the G25N-7’s braking system could reduce stopping power or safety. | Do not operate until brakes are inspected and repaired. | |
| Parking Brake | RED | The parking brake is engaged while the G25N-7 is running or in gear. | Release the parking brake before moving the forklift. | |
| Seat Belt | AMBER | The operator’s seat belt is not fastened while the G25N-7 is powered. | Buckle the seat belt before operating the forklift. | |
| Low Fuel | AMBER | The fuel level is low and the G25N-7 will soon run out if not refueled. | Refuel at the next safe opportunity. | |
| Hydraulic System | AMBER | Hydraulic pressure or fluid level is below normal, affecting lifting or steering in the G25N-7. | Inspect hydraulic fluid and system for leaks or faults. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on hours of use in your G25N-7. | Arrange for the recommended service as soon as possible. | |
| Work Lights | BLUE | Work lights are switched on to illuminate the G25N-7’s workspace. | No action needed unless lights are not required. | |
| Beacon / Rotating Light | AMBER | Beacon light is active, signaling forklift operation in the area for safety. | Ensure beacon is functioning in high-traffic or low-visibility areas. | |
| Overload / Capacity | RED | The load exceeds the safe rated capacity for the G25N-7’s lift system. | Lower the load immediately and reduce to within rated limits. | |
| Hydraulic Oil | AMBER | Hydraulic oil level or quality is insufficient for reliable G25N-7 operation. | Check and top up hydraulic oil; inspect for contamination. | |
| Air Filter | AMBER | The air filter is clogged, restricting airflow to the G25N-7 engine. | Clean or replace the air filter promptly. | |
| Fuel Filter / Water Separator | AMBER | Fuel filter is restricted or water has accumulated, risking engine issues in the G25N-7. | Drain water and replace the fuel filter as soon as possible. |

Frequently Asked Questions
What should I do if the hydraulic system light comes on during operation?
Stop the G25N-7, check hydraulic fluid level, and inspect for leaks or system faults before continuing work.
Can I keep operating if the service/hour meter light is on?
You may finish your current task, but schedule the recommended maintenance for the G25N-7 as soon as possible to prevent breakdowns.
Why is the overload light flashing even with a light load?
The overload sensor may be malfunctioning or the load may be improperly positioned; verify load placement and have the sensor checked if the issue persists.
What does it mean when the air filter light comes on?
It indicates the air filter is clogged, which can reduce engine performance; clean or replace the filter promptly.
Is it safe to drive with the parking brake light on?
No, operating the G25N-7 with the parking brake engaged can cause brake damage and unsafe conditions; always release the brake before moving.
