General Information

Thumb pressure on the feeder pushes the adhesive stick into the heat block. The adhesive is melted by the heat block and pushed out through the tip. A fixed thermostat on the heat block maintains heat block temperature.

Start-Up and Operation

WARNING: USE ONLY 3M™ SCOTCH-WELD™ HOT MELT 2’’ x 5/8’’ LOW MELT ADHESIVE STICKS. OTHER ADHESIVES MAY CAUSE BACKMELT AND POSSIBLE INJURY. DO NOT USE NEAR HIGHLY FLAMMABLE MATERIALS.

1.Plug the 3M™ Scotch-Weld™ Hot Melt Applicator LT into a 120 VAC grounded receptacle. Allow 5 to 10 minutes for heat-up.

2.Pull the feeder back toward the rear of the applicator.

3.Snap a 3M Scotch-Weld Hot Melt Adhesive Stick (5/8’’ x 2’’) into the holder.
