hook locking pin (mechanical only). Failure to

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

released. Stand clear and to one side when
releasing the attachment.

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

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
