5/8" HIGH PERFORMANCE  
GLUE GUN

NOTE: The glue gun should be unplugged 
after each use. The adhesive can be stored 
indefinitely in the unheated gun and re-melted 
by heating up the tool.

1.  Use built-in screwdriver to adjust temperature control.

 NOTE: The glue gun comes pre-set at 375°F.

2.  Plug the glue gun into a 120 volt AC outlet; when red 

light illuminates on/off switch, the power is on.

3.  Insert 5/8" glue stick into glue feed. Allow the glue 

gun to heat for approximately 3 to 5 minutes. 

CAUTION! Once glue gun heats up, the nozzle 
and melted glue are extremely hot. Avoid 

touching.

4.  When the gun is fully heated, squeeze trigger slowly. 

The melted glue will begin to flow from nozzle. 

Release the trigger to stop the glue flow.

5.  The output volume of the glue can be adjusted by 

turning the stroke adjuster clockwise.

NOTE: Use short nozzle for general use or long 
nozzle for harder to reach areas.

6.  If glue drips excessively, replace the nozzle. To 

change, heat the gun for a minute until glue is 

softened enough to remove the nozzle. While 

wearing gloves, use a wrench to remove the old 

nozzle. Flush glue through the gun and attach the 

new nozzle.
