Excavator End (Emergency Operation)
The excavator has an accumulator installed in the hydraulic pilot control system. The accumulator stores
a limited amount of hydraulic pressure for use in an emergency (motor failure for example). This hydraulic
pressure must be used to move the dipper and lower the boom into a safe position.
Do not try to operate other machine functions as this will deplete the hydraulic pressure in the accumulator and
it may then not be possible to move the dipper and lower the boom.
If an emergency occurs:
1. Turn the ignition key to the on position.
2. Enable the controls.
Refer to: Control Lock (Page 43).
3. Use the right and left control levers to move the dipper and lower the boom.
4. Vent the hydraulics.
Refer to: Discharge (Page 138).
5. Turn the ignition key to the off position.
