4.6 JIB
Removal
1. Lower the platform to the ground or onto blocking to
support the weight of the jib.
2. Tag and disconnect the electrical harnesses that run
to the jib. If necessary, loosen the guide block to
allow the harnesses and hoses to move more freely.
3. Remove the jib valve protection plate.
4. Have a container or absorption material ready to
catch residual hydraulic fluid. Tag and disconnect
the hydraulic hoses that run from the boom to the jib
control valve. It may be necessary to disconnect
additional lines to gain access to certain fittings. Cap
or plug all openings.
5. Unbolt the valve from the boom.
6. Lay the jib control valve aside on the jib. Secure it in
place so it does not fall.
