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.
CAUTION: Do not force adhesive. Excessive force
can damage the applicator and cause molten
adhesive to flow out the rear.
4. Gently press the feeder forward and push the adhesive
into the heat block. Melted adhesive will flow from the tip.
WARNING: TIP AND VALVE ARE HOT. KEEP TIP POINTED
AWAY FROM BODY PARTS.
CAUTION: To avoid charring or plugging of the tip,
extrude at least one adhesive stick every three hours that
the applicator is turned on.
