1.5 Removal and Installation
1. Place the crane in rigging mode and raise the boom. This will allow access to the hose fittings
and wiring harness connections.

removal and installation process.
2. Disconect the reeling drum cable.
3. Disconnect the swing sensor.
4. Remove the display.

6. Unscrew the four bolts and remove the old computer from its mounting place. Place the
computer on the deck.
NOTE: Do not disconnect the power and FKO cables.
7. The new computer is smaller than the existing one. Mount the new computer using one of the
existing bolt holes. Use the new computer as a template to drill three new mounting holes.
8. Screw in the remaining bolts. Ensure the computer is securely attached.
9. Lower the boom completely. Remove the exisiting pressure hoses from the old computer.
10. Install the new pressure hoses and retain the velocity fuses.
