Haulotte aerial lifts are equipped with a comprehensive instrument cluster to monitor machine health and safety. This guide explains the meaning of each warning light and provides specific actions for the Haulotte HA series, including both diesel and electric models.
Haulotte aerial lift Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical fault has been detected on your Haulotte, requiring immediate shutdown to prevent damage or injury. | Stop the machine safely, turn off the engine, and consult the fault code on the display. | |
| Master Caution | AMBER | A non-critical issue has been detected on your Haulotte aerial lift that requires attention before continuing operation. | Check the display for associated warnings and service the affected system soon. | |
| Fasten Seat Belt | RED | The operator seat belt is not fastened; Haulotte requires seat belt use for all operations above 1.8m. | Fasten your seat belt before continuing. | |
| Overload / Capacity | RED | The platform load exceeds the rated capacity of this Haulotte aerial lift, triggering an overload alarm. | Immediately remove excess weight and ensure load is within limits. | |
| Hydraulic Oil | AMBER | The hydraulic oil level is low or the system pressure is outside normal range on your Haulotte. | Check hydraulic oil level and refill if needed; inspect for leaks. | |
| Battery Discharge (BDI) | RED | The battery charge is critically low on your electric Haulotte, limiting drive and lift functions. | Recharge the battery immediately to prevent deep discharge damage. | |
| Parking Brake | AMBER | The parking brake is engaged on your Haulotte; release it before driving. | Release the parking brake to resume travel. | |
| High Beam | BLUE | The high beam headlights are activated on your Haulotte for increased visibility. | Dim when approaching other personnel or vehicles. | |
| Work Lights | GREEN | The auxiliary work lights are on, illuminating the work area on your Haulotte. | No action needed; switch off when not required to save battery. | |
| Beacon / Rotating Light | GREEN | The rotating beacon is active, indicating your Haulotte is in motion or elevated. | Ensure beacon is working for safety; clean if obscured. | |
| Check Engine (MIL) | AMBER | The engine control unit has detected a fault in the diesel engine of your Haulotte. | Have the engine diagnosed by a Haulotte technician to prevent damage. | |
| Glow Plug / Preheat | AMBER | The glow plugs are preheating the engine for cold starts on diesel Haulotte models. | Wait for the light to turn off before starting the engine. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on the Haulotte's hour meter reading. | Perform the required service per Haulotte's maintenance schedule. | |
| Air Filter | AMBER | The engine air filter is restricted and requires replacement on your Haulotte. | Replace the air filter to ensure proper engine performance. |

Most Important Warning Lights
Overload Warning
Common causes
- Platform load exceeds rated capacity
- Uneven load distribution
- Sensor calibration drift
What to do
Immediately reduce load to within limits and redistribute evenly. If error persists, have the load sensor recalibrated by a Haulotte dealer.
Hydraulic System Failure
Common causes
- Low hydraulic oil level
- Hydraulic hose leak
- Pump failure
What to do
Check hydraulic oil level and refill if low; inspect for visible leaks. For pump failure, contact a Haulotte service center.
Battery Discharge Critical
Common causes
- Extended operation without recharge
- Battery age or cell failure
- Parasitic drain
What to do
Recharge the battery immediately using the Haulotte charger. If battery does not hold charge, replace with a Haulotte-approved battery.
Engine Overheat (if applicable)
Common causes
- Low coolant level
- Radiator blockage
- Cooling fan failure
What to do
Let engine cool, check coolant level and refill. Clean radiator fins. If fan fails, seek Haulotte repair.
Parking Brake Malfunction
Common causes
- Brake cable adjustment
- Brake pad wear
- Hydraulic brake leak
What to do
Test parking brake engagement. If faulty, adjust cable or replace pads. For hydraulic issues, consult Haulotte manual.
Frequently Asked Questions
What does the red master warning light mean on my Haulotte?
It indicates a critical fault that requires immediate stop and engine shutdown. Refer to the fault code on the display and contact Haulotte service.
Why is the overload light flashing even without a heavy load?
This could be due to an uneven load distribution or a faulty load sensor. Try redistributing the load; if it persists, have the sensor recalibrated.
How do I reset the service hour meter reminder?
After performing the required maintenance, press and hold the service reset button (located on the cluster) for 5 seconds until the light turns off.
Can I operate the Haulotte with the battery discharge light on?
No, continued operation can damage the battery. Charge the battery fully before use to ensure proper lift and drive functions.
What does the amber hydraulic oil light indicate?
It means hydraulic oil level is low or pressure is abnormal. Check and refill oil, inspect for leaks. Do not operate if light stays on.
Why does the glow plug light stay on longer in cold weather?
Glow plug preheat time is extended in cold temperatures to ensure proper engine starting. Wait for the light to turn off before starting.
