The Snorkel TB85J telehandler features a comprehensive instrument cluster with warning lights for engine, hydraulics, and safety systems. Understanding these indicators is crucial for safe operation and preventing damage.
Snorkel TB85J Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system failure has been detected on your TB85J, requiring immediate engine shutdown. | Stop the engine and investigate the specific warning light that triggered the master warning. | |
| Master Caution | AMBER | Indicates a non-critical system fault that needs operator attention on the TB85J. | Refer to the diagnostic display or check for other amber warning lights. | |
| Check Engine (MIL) | AMBER | The engine control unit has detected a fault in the emissions or engine management system of your TB85J. | Have the engine diagnosed by a certified technician as soon as possible. | |
| Engine Oil Pressure | RED | Engine oil pressure is below safe operating range on the TB85J, risking severe engine damage. | Immediately stop the engine and check oil level and pressure. | |
| Battery / Charging | RED | The alternator is not charging the battery, or the battery voltage is critically low on the TB85J. | Check belt tension, alternator connections, and battery condition. | |
| Coolant Temperature | RED | Engine coolant temperature has exceeded the safe limit on your TB85J. | Stop the engine, allow it to cool, and check coolant level and radiator. | |
| Brake System | RED | A fault in the brake system has been detected on the TB85J, potentially reducing braking performance. | Stop the machine and do not operate until the brake system is inspected. | |
| Parking Brake | AMBER | The parking brake is engaged on the TB85J, or a fault exists in the parking brake circuit. | Release the parking brake before moving; if light persists, inspect brake system. | |
| Seat Belt | RED | The operator seat belt is not fastened on the TB85J, which disables machine functions. | Fasten your seat belt before operating the machine. | |
| Glow Plug / Preheat | AMBER | The engine preheat system is active on the TB85J, indicating glow plugs are warming up. | Wait for the light to turn off before starting the engine. | |
| Low Fuel | AMBER | Fuel level in the TB85J is low, which may cause engine shutdown or air in the system. | Refuel as soon as possible. | |
| High Beam | BLUE | The high beam headlights are turned on on the TB85J. | Dim when approaching other vehicles or personnel. | |
| Hydraulic System | RED | The hydraulic system pressure or temperature is out of safe range on the TB85J. | Stop operation immediately and check hydraulic fluid level and condition. | |
| Fasten Seat Belt | RED | Seat belt is unbuckled, and the TB85J will not allow operation until fastened. | Fasten the seat belt to clear the warning. | |
| Service / Hour Meter | AMBER | Indicates that scheduled maintenance is due on the TB85J based on engine hours. | Perform the required service as indicated in the operator's manual. | |
| Work Lights | GREEN | The work lights are illuminated on the TB85J for enhanced visibility. | Turn off when not needed to conserve battery. | |
| Beacon / Rotating Light | AMBER | The amber beacon light is active on the TB85J to warn nearby personnel. | Ensure beacon is functioning when operating in high-traffic areas. | |
| Swing / Slew Lock | GREEN | The swing lock is engaged on the TB85J, preventing turret rotation. | Disengage swing lock before rotating. | |
| Overload / Capacity | RED | The TB85J has detected a load exceeding its rated capacity, triggering an overload condition. | Remove excess load immediately and redistribute weight. | |
| High Exhaust Temp (HEST) | AMBER | Exhaust temperature is elevated on the TB85J, often during DPF regeneration. | Keep the machine away from flammable materials until the light turns off. |

Most Important Warning Lights
Engine Won't Start
Common causes
- Low battery voltage
- Faulty glow plug system
- Seat belt not fastened
What to do
Check battery charge and connections; ensure seat belt is buckled; wait for glow plug light to turn off before cranking.
Hydraulic System Malfunction
Common causes
- Low hydraulic oil level
- Contaminated hydraulic oil
- Clogged hydraulic filter
What to do
Check hydraulic fluid level and condition; replace filter if needed; bleed air from system per TB85J manual.
Overload Warning Active
Common causes
- Load exceeds capacity
- Uneven load distribution
- Sensor calibration error
What to do
Reduce and redistribute load; if light persists, have load sensors recalibrated by a Snorkel technician.
Brake System Failure
Common causes
- Low brake fluid level
- Worn brake pads
- Hydraulic brake line leak
What to do
Check brake fluid reservoir; inspect pads and lines; do not operate until brake system is repaired.
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage
- Faulty cooling fan
What to do
Stop engine; check coolant level after cooling; clean radiator fins; inspect fan operation.
Frequently Asked Questions
Why won't my TB85J move even though the engine is running?
Check that the parking brake is released, seat belt is fastened, and no warning lights are illuminated. The drive system may be disabled by a safety interlock.
What does the flashing amber beacon light mean?
The beacon is a warning to others that the machine is operating. Ensure it is working properly when moving or lifting.
How do I clear the service hour meter reminder?
The reminder resets after performing the scheduled maintenance. Consult the TB85J service manual for the specific reset procedure via the display menu.
Can I operate with the master caution light on?
The machine may still operate, but you should investigate the cause. If it's a minor fault, continue with caution; if performance degrades, stop and service.
What should I do if the overload alarm sounds?
Immediately stop lifting and lower the load to reduce weight. Check that the load is within the rated capacity and properly centered.
Why does the glow plug light stay on for a long time?
In cold weather, the glow plugs need extra time. Wait until the light turns off before starting. If it stays on excessively, have the system checked.
