Crown RR 5700 Warning Light Symbols
| Symbol | Name | Color | What it means | What to do |
|---|---|---|---|---|
| Master Warning (Stop) | RED | A critical system fault has been detected on the RR 5700, such as a major hydraulic or electrical failure. | Safely stop the truck and contact maintenance immediately. | |
| Master Caution | AMBER | The truck has identified a non-critical issue that may affect operation, such as a sensor error or minor system fault. | Proceed with caution and report the issue to maintenance at the next opportunity. | |
| Battery / Charging | AMBER | The battery charge level is low or the RR 5700 is not charging as expected. | Return the truck to the charging station as soon as possible. | |
| Hydraulic System | AMBER | A hydraulic system problem is affecting lift or reach functions on the RR 5700. | Stop lifting loads and request maintenance to inspect the hydraulic system. | |
| Battery Discharge (BDI) | AMBER | The battery discharge indicator shows that the truck's battery is approaching critical depletion. | Cease operation and recharge the battery to avoid an automatic shutdown. | |
| Overload / Capacity | RED | The load being lifted exceeds the RR 5700's rated capacity or the mast is overloaded. | Lower the load immediately and reduce weight to within safe limits. | |
| Mast / Lift Limit | AMBER | The mast has reached its maximum safe lift height or a lift limit sensor has been triggered. | Do not attempt to lift higher; lower the mast if needed. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due based on operating hours tracked by the RR 5700. | Arrange for routine service at the next available opportunity. | |

Most Important Warning Lights
Master Warning (Stop)
Common causes
- Major electrical failure
- Critical hydraulic leak
- System safety interlock triggered
What to do
Immediately stop using the RR 5700 and have a qualified technician diagnose and repair the underlying fault before resuming operation.
Overload / Capacity
Common causes
- Lifting load above rated capacity
- Incorrect load positioning
- Mast sensor malfunction
What to do
Reduce the load to within the truck's specified limits and verify the load is properly centered; if the warning persists, have the mast sensors checked.
Battery Discharge (BDI)
Common causes
- Extended operation without recharge
- Battery nearing end-of-life
- Charger not properly connected
What to do
Recharge the battery fully before further use; if battery drains quickly, have it tested or replaced by maintenance.
Hydraulic System
Common causes
- Low hydraulic fluid level
- Hydraulic pump failure
- Leaking hoses or fittings
What to do
Inspect fluid levels and look for leaks; if the issue is not resolved, have maintenance service the hydraulic system.

What should I do if the Master Warning (Stop) light comes on while operating the RR 5700?
Stop the truck immediately, secure the area, and report the issue to your supervisor or maintenance team.
How do I know when the RR 5700 battery needs recharging?
The battery or BDI light will illuminate when charge is low; always recharge before the indicator reaches the critical zone to avoid shutdown.
Is it safe to continue operating with the Master Caution light on?
You may continue with caution, but report the issue to maintenance as soon as possible to prevent further problems.
What does the Overload/Capacity light mean on the RR 5700?
It means the load exceeds the safe lifting capacity; lower the load immediately to protect the truck and operator.
Why would the hydraulic warning light activate on my RR 5700?
This usually indicates a hydraulic system issue, such as low fluid or a malfunction; have the system inspected promptly.
