Instructions for Use (continued)

!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.

8.Insert 3M™ Scotch-Weld™ Polyurethane Reactive (PUR) Easy 250 Adhesive Cartridges with disposable nozzle attached end first, into preheater heat chambers.

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.

9.When finished using the preheater, push the on-off switch to the “off” position.
