Working operation of the machine 5
TW85 55
5.4 Changing work attachments
5.4.1 General notes
Various work attachments are available to achieve
maximum utilization of the machine for a variety of
applications.
The machine is equipped with a quick-attach
system, to shorten the time it takes to change
attachments.
When mounting a clamshell grab, slewable ditch-
cleaning bucket or a hydraulic rock breaker, an
additional control circuit is required. Additionally,
an open return (return directly to tank) can be
required for hydraulic rock breaker operations.
Under certain circumstances, it is
possible to use the work attachments of
predecessor models on our machines.
When mounting the work attachments of
predecessor models they may have to be
adjusted and/or may be subject to
utilization restrictions. It is essential to
consult your dealer before mounting such
a work attachment.
When the attachments have been
removed, they must be secured against
tilting and overturning to avoid possible
injuries to persons.
When attaching attachments from other
companies to the excavator, you must
observe the manufacturer specifications
regarding maximum and minimum
operating pressure as well as the
permissible volume flows for this tool.
It may consequently be necessary to
carry out readjustments (e.g. to the
pressure control valves).
