Introduction
WARNING
If two people are doing this job make
sure that the person working the controls is a
competent operator. If the wrong control lever is
moved, or if the controls are moved violently, the
other person could be killed or injured.
WARNING
Do not retract the locking pins when
the lift arm is raised, the shovel could fall and kill
or seriously injure someone. Retract the locking
pins only after the attachment has been placed on
the ground.
Keep other people clear of the area while you engage
the attachment. If a second person is to be involved
in this procedure, make sure that they keep clear of
the machine and attachment until signalled by you to
proceed.
For more information on the servo-control lever and
the auxiliary controls
A Quickhitch isolator valve is installed on all
machines. This valve can be used to hydraulically
operate the locking pins to lock an attachment to the
Quickhitch. The valve is operated by the Quickhitch
isolator switch in the cab.
When the Quickhitch isolator switch is operated
at the same time as the auxiliary buttons/lever,
hydraulic pressure is diverted to the locking pins.
•
When the locking pins are fully out, they are
disengaged.
•
When the locking pins are partially out, they are
partially engaged.
•
When the locking pins are fully in, they are fully
engaged.
The red indicators show the position of the pins, the
main pins are fully engaged when the red indicators
can't bee seen anymore.
