– Always use new gaskets, making sure that they have the same thickness as
the old ones.
– Always fit gaskets of asbestos-free materials or graphite without using
lubricants (e.g. copper grease, graphite paste).
▪ Assembly adhesives
– For gaskets, avoid the use of assembly adhesives, if possible.
– If assembly adhesives are required, use a commercially available contact
adhesive (e.g. "Pattex").
– Only apply adhesive at selected points and in thin layers.
– Never use quick-setting adhesives (cyanoacrylate adhesives).
– Coat the locating surfaces of the individual components and screwed
connections with graphite or similar before reassembly.
Tightening torques For reassembly, tighten all screws and bolts as specified in this manual.
