– Do not lay the heated gun on its side. Keep the heated gun in an upright position, on the metal
stand or workbench, with the nozzle pointed down.
– If melted glue has escaped from the melt chamber entrance and is interfering with the feed
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.
SPECIFICATIONS
– 300 watts for greater glue output than with any other glue guns
– Nonbreakable handles and light weight
– Unique effort-saving trigger, with circular TPR handle for comfortable long-hour operation.
– Adjustable temperature design: work with the right temperature for the required glue
properties. Temperature is adjustable between 120°C and 230°C (248°F-446°F).
– Stroke adjustor: Each piece comes with a stroke adjustor, and allows the user to preset the
amount of glue output correctly.
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.
– The working time of the hot melt can be extended to 50-60 (fifty to sixty) seconds by applying
the adhesive in large drops, or shortened to less than 10 (ten) seconds by extruding the
adhesive in a thin line.
– 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; red light on means the
power is on.
– 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.
– The output volume of the glue can be adjusted by adjusting the stroke adjustor screw.
