Cleaning
• Do not use aggressive cleaning agents for cleaning the device. These may damage
device components.
We recommend cleaning with paraffin oil.
• Replace completely parts which are no longer cleanable (e.g. because of burnt-on or
reacted hot-melt adhesive). We recommend having this work done by the manufacturer
or distributor.
• Remove residues of hot-melt adhesive and other contaminants by mechanical means
only, e.g. with a cloth, soft brush, wooden spatula or similar.
