9. Attach an adequate supporting device to the jib to
support its weight. Remove the bolt and keeper pin
securing the jib pivot pin and remove the pin.
10. Remove the jib and platform assembly from the
boom.
11. At the rear of the turntable, tag and disconnect all
wiring harnesses that run from the powertrack to the
ground control station. The connector inside the
ground control box will have to be removed from the
wires to allow the harness to be pulled out of the
control box. It will simplify installation if a diagram of
the wiring running into the connector is made at this
time.
12. Have a container or absorption material ready to
catch residual hydraulic fluid. Disconnect the pres-
sure line going into the platform filter, taking care to
slowly bleed off hydraulic pressure. Cap or plug all
openings..
