► Do not clean the product in a ultrasonic bath and do not immerse the
product in any fluids. Let any fluid incursions drain out immediately,
otherwise there is a danger of corrosion and loss of function.
► For Kirschner wire attachment GB894R: Set the adjustment sleeve to
the greatest Kirschner wire diameter.
Phase I
► Flexible components (such as sleeves) will move during cleaning.
► Thoroughly clean the product under running water.
Phase II
► Flexible components (such as sleeves) will move during cleaning.
► Brush cannulation with cleaning brush TA011944 and difficult to
access surfaces with a suitable plastic cleaning brush for at least 1 min.
► After manual preparation, check visible surfaces for residue and repeat
the pre-cleaning process as needed.
