5. Insert 3M™ Scotch-Weld™ Polyurethane Reactive (PUR) Easy 250 Adhesive
Cartridges into preheater chambers.
Always heat cartridges for 45 minutes prior to use. Adhesive warmed less than 45
minutes in the preheater may not extrude properly from the 3M™ Scotch-Weld™
Polyurethane Reactive (PUR) Adhesive Applicator and may not exhibit optimum
bonding properties.
Adhesive will resist flowing through applicator if total heat history of adhesive
cartridge at application temperature exceeds 16 hours when used at the upper
temperature setting and 40 hours when used at the lower temperature setting
(total time in preheater and in applicator). Discard any adhesive cartridge that
has been heated longer than 16 hours and replace with a new, heated cartridge.
6. Remove adhesive cartridge and place on a bench or flat work surface with threaded
nozzle pointing upward. Allow cartridge to stand for approximately 60 seconds.

contain any adhesive and allow for
