Attaching and dismounting equipment parts
Connect hydraulic lines or electrical lines, if necessary. (eg. when attaching a grab). A direct visual check must be made to ensure that the work tool is correctly positioned. A “working cycle” should also be performed with the work tool. This means that the work tool should be raised before use to the point at which the correct positioning of, for example, the pin in the pin eye, can be checked by tilting in and out. Danger! The electronic monitoring system for the quick-change adapter displays defective functions. These could be caused by an unmonitored position change of the locking pins or by mechanical or hydraulic damage. A defect may also be present in the electrical system (eg. proximity switch or buzzer). If the buzzer and telltale light are activated without a deliberate locking or unlocking procedure being carried out, stop all work at once. If the buzzer and telltale light are not activated while a deliberate locking or unlocking procedure is being carried out, stop all work at once. Only resume working once defective parts have been repaired or replaced. Performing the working cycle Before starting to use the work tool (eg. grab, ditcher bucket), the special installation information in the chapter “Attaching and dismounting equipment parts” is also to be noted.
Detaching a work tool To move the equipment into position: Caution! Hydraulic lines are pressurized! Remove the pressure using the joystick before removing the hydraulic lines (switch off the engine, turn the ignition key into the contact position, operate the joystick). Disconnect hydraulic lines or electrical lines, if necessary (eg. when dismounting a grab). Extend the shovel tilting cylinder fully. To unlock the quick-change adapter:
