Operating information

Please observe the following tips and information so that you are able to
continuously achieve perfect adhesive application.
• Surfaces to be glued should be at room temperature and free of dust,
grease and moisture. Remainders of wax, separating oils, plasticizers
or impregnation media on the workpieces can lead to loosening of the
adhesion immediately or later.
• Apply the hot-melt adhesive using points or lines. Larger adhesive points
remain adhesive longer than small ones. Immediately after applying the
adhesive, press the workpieces firmly together for a few seconds.
• Apply the adhesive slowly and continuously so that the processing
temperature is not fallen below.
3.6 Changing the adhesive
If you want to change the adhesive type, push the remains of the old
adhesive out with the new adhesive candle.
You should never pull the old adhesive candle out of the device.
This can cause damage to the transport mechanism.
