The overload warning device (if equipped) senses
hydraulic pressure in the boom lift circuit. When the
hydraulic pressure in the boom lift circuit reaches a
predetermined pressure setting, a buzzer will sound that
indicates an overload condition.
If the buzzer sounds, immediately move the arm closer to the excavator and lower the boom. Reduce the size of the load before attempting to re-lift the load.
