Part 107105C04
WARNING: Risk of death or serious injury from explosion or fire can occur
if Nordson Type R fluid is heated above 245 _C (475 _F). Do not use
Nordson Type R fluid on surfaces above 245 _C (475 _F).
NOTE: Nordson Type R fluid is used to clean adhesive from extrusion
systems. Its advantages over similar fluids are that it can be reused and
that it has an inoffensive odor.
1. Bring handgun to operating temperature.
2. Soak a cloth in Nordson Type R fluid (or equivalent).
3. Wipe adhesive from all exterior handgun and nozzle surfaces with the
fluid-soaked cloth.
Clean all nozzles weekly unless operating experience mandates more
frequent cleaning. Plant environment and the type of adhesive used are
some factors that can affect cleaning frequency.
