General
WARNING Always install the quickhitch latch hook locking pin (mechanical only). Failure to install the pin
will result in possible failure of the latching mechanism. Such a failure could result in the sudden release of
an attachment from the machine and you or others could be killed or seriously injured.
WARNING The attachment will move when released. Stand clear and to one side when releasing the
attachment.
WARNING The quickhitch sequence must not be entered unless a constant tone buzzer is heard. This can
be identified on start up of the machine. Check the constant tone buzzer operation daily.
WARNING If a second person is involved with the operation ensure that the machine controls are not
operated whilst they are in the working envelope of the machine and attachment, otherwise the other person
could be killed or injured if a control is moved accidentally.
WARNING Should there be an unsuccessful pin engagement during the installation of the attachment the
unlock process must be repeated. Extra care must be taken during this process as the attachment may be
able to disengage from the quick hitch.
WARNING Make sure that the latch hook has fully engaged, otherwise the attachment could fall and you
could be killed or injured
CAUTION When the quickhitch is installed and its attachment attached, It is possible to strike the cab and
the underside of the boom or dipper with some attachments. Use great care with the boom and dipper to
keep the attachment away from the operator cab.
CAUTION When the quickhitch is attached to the machine, allowance must be made for the weight of the
quickhitch on the rated operating load. The mass of the Quickhitch is stamped on the data plate.
The Excavator Quickhitch, which is attached to the dipper enables the fast removal and installation of the
bucket (and other attachments).
Compatibility of the Quickhitch must be checked with Quickhitch manufacturer. Refer to the Quickhitch system
pressure figures. Refer to: Hydraulic System (Page 162).
Put the Quickhitch attachments on solid, level ground to make the installation procedure safe and easier.
