Hydraulic Boom Extension Connections
Use the following procedures to connect and disconnect the
optional hydraulic boom extension to the main boom.
Disconnect and retract the hydraulic lines from the boom
nose whenever the operation of the crane does not require
hydraulic power. This will extend the life of the hose drum,
hoses, and associated hardware. For more information, see
Retracting Hydraulic Hoses for Main Boom Operation, page
5-76.
Checking the Locking Device on the Hose
Drum
The hose drum on the side of the main boom provides the
hydraulic supply to the boom nose hydraulic boom
extension. The hose drum is equipped with a locking device.
The drum must be unlocked before operation.
If the hose drum must be removed, the drum must be locked.
For more information about removing the hose drum, see the
Service Manual.
CAUTION
Equipment Damage Hazard!
Always verify the drum is unlocked before using
extensions or other equipment that require hydraulic
power. Damage to hydraulic hoses or the boom may
occur.
