Frequently Asked Questions
What should I do if the BDI (Battery Discharge Indicator) is in the red zone?
Stop using the EFG 320 and recharge or swap the battery to avoid deep discharge and potential battery damage.
Why does the Overload warning appear even with a light load?
Check for correct load placement and ensure the load sensor is functioning; a faulty sensor may trigger false warnings.
How often should I service the EFG 320?
Follow the hour meter and service indicator; typically, maintenance is required every 500 operating hours or as specified in the manual.
Can I keep operating if the hydraulic oil light is on?
It's best to top up or replace hydraulic oil promptly; ignoring this warning can lead to expensive repairs or unsafe operation.
