Instructions for Use (continued)

8. Insert 3M™ Scotch-Weld™ Polyurethane Reactive (PUR) Easy 250

Adhesive Cartridges with disposable nozzle attached end first, into

preheater heat chambers.

!WARNING

Do not use an unapproved

extension cord with the

preheater. Use of an improper

extension cord may cause

electrical shock. Use an

extension cord which complies

with NEC requirements and

state and local codes and other

requirements.

!Caution

Avoid contact with top surface

and metal heating chambers of

preheater during use and hot

adhesive cartridges and

adhesive. May cause burns.

IMPORTANT: Wear heat

resistant gloves and safety

glasses when using.

!WARNING

Use only 3M™ Scotch-Weld™

Polyurethane Reactive (PUR)

Easy 250 Adhesive Cartridges.

Use with any other material may

cause hazardous conditions.

Note

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.

Important

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.

See the 3M™Scotch-Weld™ Polyurethane Reactive (PUR) Easy 250

Adhesive Applicator’s User Manual for adhesive loading and operating

instructions.
