If contaminated, for hygienic reasons it is recommended to replace the gripper head. To do so, grasp the plastic holder (not the flexible gripping jaws) with your thumb and forefinger and firmly pull it off the shaft of the Tickgripper until the head is released with a click.
To attach the new gripper head, hold the Tickgripper shaft and the gripper head aligned to each other at the given positioning marks. You will hear a click once you have successfully attached the gripper head to the shaft of the Tickgripper.
Important: Do not tilt, twist or jam! Remove or affix the gripper head only in the longitudinal axis of the Tickgripper shaft.
