5 Operation
“High Flow” hydraulic connections
Damage to hydraulic hoses of attachment during
extension or retraction of the telescopic boom.
► Do not extend the telescopic boom if the hydraulic
hoses of the attachment are connected to the
hydraulic “High Flow” connections. The connections
are firmly fastened on the outside section and cannot
be extended with the telescopic boom.
The “High Flow” hydraulic connections are located on the
right of the loader unit. Red connection (F) = feed. Blue
connection (R) = return.
This connection is required for the operation of constant-
running attachments requiring a higher oil flow rate.
► Proceed as described in chapter Coupling/uncoupling
hydraulic connections from the mast on page 5-52 for
coupling and uncoupling.
► Only connect the hydraulic “High Flow” connections if
the telescopic boom is to be operated when it is
retracted.
