3.5.5.1Safety instructions

–Make sure that there are no persons in the attachment area during the installation and removal of working tools. Move the attachment as slowly as possible when installing or removing a working tool. Familiarize yourself with the operating principle of the quick change adapter before installing or removing any working tools.

–Always keep the working tool as close to the ground as possible when locking and unlocking to avoid dangerous movements.

–If necessary, use a platform to reach the locking pins and connections. Never stand on the working tool or attachment.

–Each time a working tool is changed, the machine operator must ensure that the locking pins for the quick change adapter are inserted in the proper bore holes on the working tool and that the working tool is attached properly. Check visually to ensure that the working tool is tightly seated.

–In addition, carry out a work cycle with the tool, but only lift the tool to the point where the seating can be checked, for example the pin in the pin eye, by curling the bucket in and out.

–The locking screw must be checked daily to ensure it is still seated tightly.

–The load carrying capacity of the quick change adapter or the integrated load hook can exceed or fall below the load carrying capacity of the carrier machine. During operation, make sure that the values given in the load chart and the technical data of the carrier machine are adhered to.
