IMPORTANT
When using electric tools, basic safety precautions should
always be followed to reduce the risk of fire, electric shock and personal
injury.
DUAL TEMP
®
SETTINGS
Switching from the HIGH TEMP setting of your ARROW GT20DT™ to the
LOW TEMP setting increases the number of jobs that you are able to do with
your new hot melt glue gun.
LOW TEMP — 302°F (150°C). The Arrow “ALL PURPOSE” glue sticks are
also designed to melt at the cooler setting to protect fragile materials with
low melting points. Delicate materials such as lace, foil, ribbon, floral forms
and lightweight fabric can now be beautifully decorated with much less risk
of damage (see FIGURE 2).
HIGH-TEMP — 380°F (193°C). Switch the TEMP setting to HIGH and the
ARROW “ALL PURPOSE“ glue reaches 380°F (193°C) for a more liquid
consistency. This means a more thorough seepage and bonding for heavy
duty jobs on wood, plastics, ceramic, leather, and cardboard surfaces (see
FIGURE 3).
ASSEMBLY
MAKE SURE YOU HAVE READ ALL SAFETY INSTRUCTIONS.
• Select your temperature setting based on the type of material you are using and the type of project application.
• Insert 5/16” (8mm) diameter glue stick through tunnel at back of gun (see FIGURE 1).
• Plug cord into an electrical outlet and wait 3-5 minutes to heat up the glue.
• When first using your new glue gun it will take (1) stick of glue to fill the melt chamber before glue begins to flow out.

• After hot glue reaches working temperature, direct glue
gun nozzle towards target workpiece area, squeeze
trigger to apply melted glue.
• Insert new glue sticks when old one is totally drawn into
the rear of the tool.
• Apply hot melt glue by continuous pressure on the
trigger.
NOTE: the rate of glue can be controlled by the rate at
which pressure is applied to the trigger during application
and how far the trigger is pulled. Slow steady pressure on
the trigger will reduce the rate of glue flow and produce a
long, thin bead of glue. Squeezing the trigger quickly with
high pressure will increase the rate of glue flow and
produce a heavy short bead of glue.
• Once hot glue is applied to the workpiece, apply
pressure to the work piece for approximately 30
seconds. Use of clamps or other holding devices is not
necessary. Clean surfaces are best for bonding.
• Repeat glue application throughout project as needed.
• Unplug the glue gun when not in use and let cool
completely before storing the glue gun. After glue gun
has cooled to touch, store in clean, dry area.
• Do not attempt to remove unused glue from the glue gun
after use. Any unused portion of the glue stick will remain
in the glue gun and can be reheated for later use.
If, when squeezing trigger, glue does not enter gun easily, DO NOT continue to squeeze trigger.
Glue chamber may not be hot enough to melt glue fully.
Excessive squeezing of trigger may cause hot glue to back up and flow out of rear of gun,
possibly causing severe burns.
TIPS ON USING
1. The working time of hot melt glue can be extended
to fifty or sixty (50 to 60) seconds by applying the
adhesive in large drops (1/2” diameter) or shortened
to less than ten (10) seconds by extruding the adhesive
in a thin line.
2. Large areas are difficult to bond because the adhesive
frequently will harden before you have extruded the
right amount
3. Preheat surfaces, (especially metals) to improve bond
strength. Direct sunlight will accomplish this.
4. The adhesive remaining in an unheated glue gun will
re-melt upon heating.
5. Do not use on items that will be subject to temperatures
above 140˚F (60˚C).
6. Do not use hot melt glue to hold hot heavy loads.
7. Some paints and stains can weaken the adhesive. You
may need to paint or stain before gluing.
8. Always practice gluing on scrap work pieces before
final gluing on projects.
