Establishing/Disconnecting the Hydraulic
Connection
The hydraulic supply is required for derricking the lattice
extension. Before establishing the connection, the
connections on the hose drum must be in the working with
the lattice extension position.
CAUTION
Risk of damage to hydraulic hoses!
When establishing the connection, always move the
hoses right out of the 33 ft (10.1 m) section. If the hoses
are moved out of the front of the 33 ft (10.1 m) section,
they will be damaged if the lattice extension turns.
