The JCB Telehandler aerial lift combines the functionality of a telehandler with aerial work platform capabilities, featuring specialized warning lights to ensure safe operation at height. Understanding these indicators is crucial for preventing tip-overs and maintaining stability during load handling.
JCB Telehandler aerial lift Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault has occurred in the JCB telehandler's control system, requiring immediate machine shutdown. | Stop all operations and turn off the engine; consult the operator manual for fault codes. | |
| Master Caution | AMBER | One or more secondary warnings are active on your JCB telehandler, but the machine can still be operated with care. | Review other warning lights on the cluster and address any highlighted issues. | |
| Check Engine | AMBER | The engine management system on your JCB telehandler has detected a fault that may affect performance or emissions. | Reduce load and schedule dealer diagnostics to prevent further damage. | |
| Engine Oil Pressure | RED | Engine oil pressure in your JCB telehandler is below safe level, risking severe engine damage. | Stop immediately, check oil level, and inspect for leaks before restarting. | |
| Battery / Charging | RED | The alternator is not charging the battery on your JCB telehandler, possibly due to a failed belt or alternator. | Stop the machine and have the charging system inspected to avoid a breakdown. | |
| Coolant Temperature | RED | Engine coolant temperature in your JCB telehandler is critically high, risking overheating and warping components. | Stop immediately, let engine idle to cool, and check coolant level and radiator cleanliness. | |
| Brake System | RED | A fault in the braking system of your JCB telehandler could reduce stopping ability, especially under load. | Do not operate; have the brake system serviced immediately. | |
| Parking Brake | AMBER | The parking brake on your JCB telehandler is engaged or not fully released; machine movement may be restricted. | Ensure the parking brake is fully disengaged before driving. | |
| Seat Belt | RED | The operator's seatbelt in your JCB telehandler is not fastened; operating without it is unsafe for aerial work. | Fasten seat belt immediately before moving the machine or elevating the boom. | |
| Glow Plug / Preheat | AMBER | The glow plugs are heating for cold start on your JCB telehandler; wait until the light goes out. | Turn the key to preheat and wait for the light to extinguish before cranking. | |
| DPF / Regeneration | AMBER | The diesel particulate filter in your JCB telehandler needs regeneration to clear soot buildup. | Drive the machine at higher engine speeds or initiate parked regeneration as per manual. | |
| DEF / AdBlue | AMBER | Diesel exhaust fluid level is low in your JCB telehandler; eventually engine power will be limited. | Top up DEF at the next opportunity to avoid limp mode. | |
| Low Fuel | AMBER | Fuel level in your JCB telehandler is low; continued operation may cause air entry into the system. | Refuel as soon as possible to prevent fuel starvation. | |
| High Beam | BLUE | High beam headlights are activated on your JCB telehandler for improved visibility in dark conditions. | Dim when approaching other vehicles or personnel. | |
| Hydraulic System | AMBER | A hydraulic system issue is detected on your JCB telehandler, possibly affecting boom and fork functions. | Check hydraulic oil level and look for leaks; reduce load and operate cautiously. | |
| Hydraulic Oil | RED | Hydraulic oil temperature or level is critical on your JCB telehandler, risking pump damage. | Stop machine, allow hydraulics to cool, and check oil level after the system has rested. | |
| Work Lights | GREEN | Work lights are illuminated on your JCB telehandler for area lighting during low-visibility operations. | They are on; switch off when not needed to conserve battery. | |
| Beacon / Rotating Light | GREEN | The amber beacon on your JCB telehandler is active, indicating the machine is in operation. | Ensure it is on whenever the engine is running for safety. | |
| Overload / Capacity | RED | The load on your JCB telehandler exceeds the rated capacity for the current boom angle and extension. | Immediately lower the load or reposition to a safer configuration to prevent tip-over. | |
| Mast / Lift Limit | AMBER | The boom or forks are near their maximum height or reach limits on your JCB telehandler. | Avoid further extension; retract or lower to stay within safe operating envelope. |

Most Important Warning Lights
Overload Condition
Common causes
- Exceeding capacity chart limits
- Improper boom angle or extension
- Load shift during operation
What to do
Immediately lower the load to the ground, retract boom fully, and reposition to within rated capacity. Ensure the load is centered on forks and the machine is on level ground.
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage from debris
- Faulty coolant fan or thermostat
What to do
Stop the machine and let the engine idle to cool. Check and top off coolant once cool, clean radiator fins, and inspect fan belt tension. If persistent, contact JCB service.
Hydraulic System Failure
Common causes
- Low hydraulic oil level causing cavitation
- Leak in high-pressure hose
- Contaminated oil leading to valve sticking
What to do
Park the telehandler on flat ground, lower all attachments, and shut off engine. Inspect fluid level and look for external leaks. Refill with approved JCB hydraulic oil and seek dealer repair for internal issues.
Brake Malfunction
Common causes
- Worn brake pads or discs
- Air in hydraulic brake lines
- Defective brake pressure switch
What to do
Do not operate the telehandler. Check brake fluid reservoir level and inspect for leaks. If fluid is low, top off and bleed brakes. Immediate service by a qualified technician is required.
Frequently Asked Questions
Why does my JCB telehandler show a master warning light when starting?
The master warning light illuminates briefly during the start-up self-test on your JCB telehandler. If it stays on, a critical fault has been detected; refer to the fault code display and consult the manual.
Can I drive the telehandler with the DPF regeneration light on?
Yes, you can continue driving your JCB telehandler, but it is recommended to drive at higher engine speeds to facilitate passive regeneration. If the light flashes, parked regeneration may be needed.
What does the hydraulic oil temperature warning mean for my aerial lift?
It indicates the hydraulic oil in your JCB telehandler is too hot, which can degrade performance and damage components. Reduce workload, allow the system to cool, and check oil level.
How do I interpret the overload warning on the telehandler display?
The overload warning on your JCB telehandler means the load exceeds the safe working capacity at the current configuration. Immediately lower the load and retract the boom to avoid tipping.
Why is my seatbelt light flashing even when buckled?
This could be due to a faulty seatbelt buckle sensor in your JCB telehandler. Inspect the buckle for debris and ensure the latch is fully engaged. If the issue persists, contact JCB service.
When should I use the work lights on my telehandler?
Use the work lights on your JCB telehandler in low-light conditions for safe operation around obstacles and personnel. Turn them off when not needed to preserve battery life.
