WARNING! Indicates a hazardous situation
which, if not avoided, could result in serious
injury or death.
CAUTION! Indicates a hazardous situation
which, if not avoided, could result in minor or
moderate injury and/or property damage.
NOTE: Indicates a situation which, if not
avoided, could result in property damage.
WARNING! To reduce the risk of electrical shock
or injury, observe the following safety rules:
• This appliance is not intended for use by
people (including children) with reduced
physical, sensory or mental capabilities,
or lack of experience and knowledge,
unless they have been given supervision or
instruction concerning use of the appliance
by a person responsible for their safety.
• Children or people needing supervision
should be supervised to ensure they do not
play with the appliance.
• Operate and service the glue gun only as
described in these instructions.
• Connect glue gun only to a properly
grounded outlet.
• Do not unplug the glue gun by pulling on the
cord. Grasp the plug, not the cord, to unplug.
• Do not handle the plug or glue gun with wet
hands.
• Do not use the glue gun outdoors or on wet
surfaces.
• Do not use glue gun if cord or plug is
damaged.
• Do not use glue gun if it is not working
properly or has been damaged, submerged
in water or left outdoors.
• Use only authorized replacement parts. Use
of other replacement parts may cause
hazardous conditions or damage to the glue
gun. Repairs should only be performed by a
qualified repair person.
• If supply cord is damaged, it must be
replaced by a qualified repair person or
Uline. Reach out to Uline at 1-800-295-5510
for assistance.
• Do not use near highly flammable materials.
• If an extension cord is used, use an extension
cord that complies with local electrical
requirements and is properly rated for your
application. Use of an improper extension
cord may cause electrical shock.
• Do not clean or remove the 3M™ hot melt
adhesive with solvent. It may cause a fire.
For additional health and safety information,
see product label and safety data sheet for
3M™ hot melt adhesive used.
• Do not modify the plug provided with
the glue gun or use with an adaptor or
ungrounded outlet. Improper grounding
connection of the glue gun may cause
electric shock. Check with a qualified
electrical or service person to determine
whether the plug is properly grounded. If the
plug will not fit the outlet, have a qualified
electrician or service person install the
proper outlet.

• This tool must be placed on its stand when
not in use; do not leave tool unattended
when switched on.
• Place tool on its stand after use and allow it
to cool down before storage.
• This tool is intended for use at altitudes not
exceeding 6,561'. Prior to making any repairs
on the glue gun, ensure that the glue gun
is at room temperature and that electrical
service lines have been discontinued. Failure
to disconnect the electrical power source
could result in electrical shock or damage to
the glue gun. Glue gun must be completely
assembled before connecting glue gun to
electrical outlet. Allow glue gun to cool to
room temperature before servicing. Failure
to do so may cause burns. Read instructions
before servicing.
CAUTION! Avoid contact with hot adhesive
and glue gun tip. This may cause burns. Wear
personal protective equipment per workplace
and industry standard operating procedures
when using, cleaning or charging tip. Keep tip
pointed away from body parts.
• Do not damage the back sleeve.
• Do not pull adhesive sticks from rear of glue
gun while in operation. Removing adhesive
from the rear may cause molten adhesive
flow out of the rear of the glue gun which
may cause burns and damage to the glue
gun.
• Use only 3M™ adhesive sticks. Other
adhesives may cause back melt and
possible injury. Use of other adhesives may
damage the glue gun or result in hazardous
conditions.
• Do not use low-temperature adhesives with
high-temperature glue guns.
• Reduce risks associated with hazardous work
positions to avoid minor or moderate injuries.
• Avoid raising the elbow, bending the wrist,
reaching and bending over when using this
device.
• Gently squeeze the trigger to push 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.
NOTE: To avoid charring or plugging of the tip,
extrude at least one adhesive stick every three
hours that the glue gun is turned on.
• Do not overtighten. This could damage
threads.

OPERATION
WARNING! Use only 3M™ hot melt adhesive
TC or Q sticks. Other adhesives may cause
back melt and possible injury. Do not use near
highly flammable materials.
NOTE: TC sticks are 5/8 x 2", while Q sticks are
5/8 x 8".
NOTE: Use only a 110V-230V grounded
receptacle. Allow 6-10 minutes to heat up
before using.
WARNING! Tip and valve are hot. Keep tip
pointed away from body parts.
NOTE: To avoid charring or plugging of the tip,
extrude at least one adhesive stick every three
hours that the glue gun is turned on.

NOTE: Do not connect to main electrical supply
at this point.
1. Attach tool stand (1).
2. Load tool by inserting an adhesive stick into rear
loading hole (2). (See Figure 1)
3. Operate trigger (3) to feed stick forward until
resistance is felt. Use bolt to adjust trigger tension.
(See Figure 2)
4. Connect to electrical supply and switch on tool (4).
5. Wait six minutes to warm up.
6. Operate the trigger to extrude adhesive until the
stick has been drawn into the tool.
7. Gently squeeze trigger to push the adhesive into the
heat block. Melted adhesive will flow from the tip.
(See Figure 3)
CAUTION! Do not force adhesive. Excessive
force can damage the glue gun and cause
molten adhesive to flow out the rear.
8. Insert additional adhesive sticks as needed (2).
NOTE: Remove tool stand prior to use.

MAINTENANCE
PREVENTATIVE MAINTENANCE
CAUTION! Avoid contact with hot adhesive
and glue gun tip. This may cause burns. Wear
personal protective equipment per workplace
and industry standard operating practices
and procedures when using and cleaning
or changing tip. Keep tip pointed away from
body parts.
To maintain proper operation, follow these steps:
1. Inspect nozzle tip daily. Ensure it is clean and clear
of foreign matter.
2. Keep adhesive clean and free of airborne
contaminants.
AVOIDING PROBLEMS
• Ensure tool has reached temperature before
operating.
• Do not leave tool switched on for long periods
without use. If tool is not to be used for more than
40 minutes, switch off and restart when required.
• Never lay tool on its side without optional side
inserts. Always use tool stand provided.
• Only use adhesives designed for use with this tool.
• Never remove a partially used glue stick. This can
lead to irreparable damage.
• Hot melt glue can be used instead of nails,
staples, tapes and liquid glues. They should not
be used in place of structural connections when
heavy loads are involved.
• Do not use hot melt glue for objects that are
exposed to extreme heat. Some glues that can
be used in this tool will soften at 140ºF.
9. Shut-off: Switch off tool and disconnect from the
main supply (4).
10. Provided side inserts are attached to bottom of the
tool stand. These can be installed to prevent the
glue gun from lying completely flat. (See Figures 4-5)
11. Optional: Extrude one adhesive stick to cool down
the glue gun.

TROUBLESHOOTING
OPERATING ISSUE CAUSES RECOMMENDATIONS
Low or no
adhesive flow.
No heat. Check to see that the electrical 120 Vac service is turned on.
Thermal fuse in the thermostat may have blown.
Shutdown procedure
was not observed.
Allow the glue gun to heat up for at least 30 minutes.
Plugged tip. If the glue gun was left overnight, the tip may be plugged.
This may block adhesive flow and cause backmelt.
CAUTION! Do not force adhesive. Clear the tip with
a small nail or paperclip. Extrude the remaining
adhesive stick and one new adhesive stick to clear
the opening.
Backmelt. Remove the clip and feeder from the track of the glue
gun. Push the existing adhesive stick back into the sleeve
approximately 3/4" with a new adhesive stick. Remove the
new adhesive stick before it melts and look into the black
sleeve. Look for a thin skin of adhesive around the inside of
the black sleeve. Scrape this skin toward the heat block.
CAUTION! Do not damage the black sleeve. Extrude
one adhesive stick to clear the sleeve.
To avoid backmelt, observe the start-up and shut-down
procedures. Do not force adhesive through the glue gun.
Dripping nozzle.*
Backmelt. Refer to preceding paragraph on backmelt.
Contaminated
adhesive.
Keep adhesive clean and free of contamination.
*Thermal expansion may cause some dripping during start-up. This is normal.
