mechanism, allow the gun to cool, and gently remove obstructing glue.
– Replace the nozzle if glue drips excessively. Do not attempt to change the nozzle when
glue is cold. To change the nozzle, the gun must be heated until glue is softened
enough to remove the nozzle (about 1 minute). Use gloves and, with a wrench, remove
the old nozzle. Flush glue through the gun, to clean out the melting chamber. Replace
with a new nozzle. Tighten only until snug. Do not overtighten.
– Keep the outside of the glue gun clean.
TIPS ON USE
The following guide provides helpful information for the glue gun and hot melt adhesives.
– The normal working time of the hot melt is 30 (thirty) seconds. After the adhesive has been
extruded onto the bonding surface, the part should be pressed together within 15-20 (fifteen to
twenty) seconds. The bond will have about 90% of its bond strength in one minute.
– Large areas are difficult to bond because the adhesive will harden before you have extruded
the required amount.
– Preheating the bonding surface to slightly above room temperature will improve the bonding
strength. Direct sunlight will improve this. This action is particularly important when gluing
metal pieces.
– The hot melt adheres well to porous surfaces like paper, cloth, particleboard, and pinewood.
– The hot melt adhesives quick set time eliminates the need for clamps or any other holding
devices.
– The hot melt begins to soften when temperature exceeds 60°C (140°F) and should not be
used for any items that will be subjected to temperatures above that.
– Hot melt adhesives should not be used to replace structural fasteners where heavy loads are
involved.
– Glue strings from the nozzle. If your glue is stringing from the nozzle and you want to swirl the
nozzle in a circular motion, the heat of the nozzle will cut the string. If the glue string lands on
your project, allow the glue to dry, then take a hair dryer and blow off the glue string.
OPERATION
– Plug the glue gun into any AC outlet with the required specifications.
– Allow the tool to heat for approximately 3-5 minutes. Insert a stick of adhesive into the back of
the tool.
– When the gun is fully heated, squeeze the trigger slowly, until the melted material begins to
flow from the nozzle. Release the trigger to stop the glue flow.
SAVE THESE SAFETY RULES FOR FUTURE USE:
– It is normal for this tool to become quite warm during use. This is normal and does not indicate
a problem.
– The glue gun should be unplugged after use or if it is not used within 2 hours. The adhesive
can be stored indefinitely in the unheated gun and remelted by heating up the tool.
– If you accidentally touch the molten hot glue, immediately immerse the affected area in
cold water and call a doctor. The injured area should be attended by a medical
professional.
– Some materials are heat-sensitive and can be damaged by the hot nozzle or even the hot
glue. Whenever possible, test a piece of scrap material or a hidden portion of the object being
repaired.
