Emergency Operations
NOTE: If a replacement hose is not available, the adjacent boom extend
line (2) can be used to replace the failed boom retract line (1).
6. Remove the failed boom retract line (1) from the circuit.
7. Remove and temporarily reposition the adjacent boom extend line
(2) in place of the failed boom retract line (1).
IMPORTANT! During the remaining steps, hydraulic oil will drain out of the
base end of the boom cylinder. The escaping oil should be deflected by
some means (the failed hose could be used) directing the oil into the drain
container.
8. Check the hydraulic oil level and add oil if needed.
9. Return to the cab, fasten your seat belt and start the engine.
10. Tilt the carriage and/or attachment upward if necessary for
clearance before retracting the boom.
11. SLOWLY RETRACT the boom.
12. SLOWLY LOWER the boom and ground the carriage and/or
attachment.
13. Completely remove the load from the carriage and/or attachment if
you haven’t already done so.
14. Have the vehicle serviced immediately.
15. Replace any faulty hydraulic lines.
16. Return to the cab, fasten your seat belt and start the engine.
17. Cycle the extend/retract cylinder several times to bleed air from the
system. Check for leaks.
18. Transfer the waste oil to a container with a cover and label as used
oil. Dispose of properly.
19. Recheck the hydraulic oil level. Add if necessary.
WARNING:
Wear protective clothing and proper eye
protection when working with or around hydraulic oil. Wait for
hydraulic oil to cool before attempting to repair the failure. Hot
hydraulic oil can cause severe burns and other serious injury.
