Attaching and dismounting equipment parts
Move the equipment until the lower mount of the industrial stanchion is between the bearing points of the grab mounting 1. Guide in bolt 4 and secure using disk 6. Connect hydraulic hose 11 and hydraulic hose 12 for the shell cylinder supply to the pipes for the shovel tilting cylinder. For a grab with a hydraulic torsional mechanism, also connect hoses 13 and 14 to the pipes for this auxiliary device.
Operating the grab Carry out all work movements several times without a load (open and close the shell or move the grab to the left and to the right) so that any air that may be present in the hydraulic circuits can escape.
Dismounting the grab Set the grab down onto level ground with the shell fully opened. Turn off the engine and, with the ignition key in the contact position, push the right joystick (for Open and Close grab)briefly to the left and then to the right in order to remove the pressure in the hydraulic circuits. To relieve the grab’s torsional mechanism, press the two pushbuttons in the left (or left and right – optional extras) joystick for “Turn grab”. Separate hydraulic hose 11, hydraulic hose 12 and, if present, hydraulic hoses 13 and 14 from the pipes on the shovel arm. Close open lines immediately to prevent any dirt entering. Support the grab so that it is stable. Unscrew disk 6 and knock bolt 4 carefully out. You may have to start the engine and raise the equipment slightly to do this.
