Page 34: Glue Filter Replacement
Do not use alcohol to clean the system. 5.4 GLUE FILTER REPLACEMENT PREO applicators have a disposable glue filter for hot-melt adhesives, designed to prevent adhesive slag and carbonisation while it is being pumped from the tank. The filter (positioned inside the manifold) must be replaced on the basis of the use and technical characteristics of the adhesive used.
Page 35: Cleaning The Melting Tank
• Let all the glue flow out and then close the valve again. All PREO applicators are made using advanced technology and avant-garde coatings. Despite this, in order to ensure a long working life, we recommend © Copyright 2006 PREO SRL...
Page 36: Fuse Replacement
Only use Ecocleaner 96 to clean the system, since the use of other products could irreparably damage the seals. PREO recommends this product because it is completely biodegradable, chemically inert, non-toxic and does not stick to the walls of the tank, allowing for perfectly safe use of the system.
