Assembly aids Avoid the use of assembly adhesives if possible.
Should an assembly adhesive be required after all, use a commercially available
contact adhesive (e.g. Pattex) or sealant (e.g. HYLOMAR or Epple 33).
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 with graphite or similar
before reassembly.
Prior to reassembly, screw back any forcing screws and adjusting screws.
Tightening torques For reassembly, tighten all screws and bolts as specified in this manual.
