What to do if HIAB 377 HiPro CD Construction Equipment crane does not react to controls but indicator lamps light up?

If the HIAB Construction Equipment crane doesn't react to controls, but the indicator lamps on the user panel light up, it might be in an OLP (Overload Protection) situation. Try performing movements to reduce the load moment. If necessary, release the OLP.
