Most Important Warning Lights
Master Warning (Stop)
Common causes
- Severe electrical system error
- Critical hydraulic failure
- Major safety interlock triggered
What to do
Immediately stop the ESR 5200, turn off the key switch, and call for authorized service support to diagnose and repair the fault before resuming use.
Overload / Capacity
Common causes
- Attempting to lift a load beyond rated capacity
- Incorrect load positioning
- Sensor malfunction
What to do
Lower the load to a safe weight, verify load placement, and ensure the mast sensors are functioning. If the warning persists with a safe load, arrange for service.
Brake System
Common causes
- Brake actuator fault
- Low brake fluid
- Worn or damaged brake components
What to do
Do not operate the ESR 5200 until the braking system has been inspected and repaired by trained maintenance personnel.
Battery / Charging
Common causes
- Battery voltage below safe operating range
- Loose battery connections
- Battery nearing end-of-life
What to do
Check battery charge status, inspect connections, and replace the battery if it no longer holds adequate charge.
Frequently Asked Questions
What should I do if the Battery Discharge (BDI) light comes on during a shift?
Plan to return to the charging area soon; continued use may lead to automatic truck shutdown to protect the battery.
Why is the Overload light flashing even with a light load?
Check the load positioning and ensure the forks are not extended beyond the rated capacity. If the warning persists, the mast sensors may require calibration.
Can I keep operating if the Master Caution light is on?
You may continue working briefly, but inspect the display for details and address the issue as soon as possible to avoid escalation.
How do I reset the Service / Hour Meter light?
After scheduled maintenance is completed, the reset procedure must be performed using the ESR 5200’s onboard menu or by a technician.
What does it mean if the Hydraulic System indicator appears?
This signals a possible hydraulic fluid shortage or system fault; check fluid levels and inspect for leaks before further operation.
