INSTALLING/REMOVING NOZZLES
See Figure 3, page 9.
To install:
 Make sure the glue gun is turned off, the battery is re-
moved, and the glue gun has properly cooled before
replacing the nozzle.
 Choose the correct nozzle for your application.
 Thread the desired nozzle into the front of the glue gun.
 Use a 12 mm wrench (not included) to tighten.
To remove:
 Remove the rubber nozzle sleeve.
 Using a 12 mm wrench (not included), turn nozzle coun-
terclockwise when viewed from the nozzle tip to remove
from the glue gun.
NOTE: If the glue has caused the tip to become difficult
to remove, then use a standard 12mm wrench or pliers
to provide extra leverage.
OPERATION
Purpose
Versatile and suitable for
general use.
Perfect for working in nar-
row or tight spaces. Has
smaller opening and elon-
gated tip.
Designed for increased hot
melt glue dispensing. Has
a large opening at the end
of a flat tip that provides a
wide coverage area.
Great for reaching difficult
places in many packaging
applications.

HELPFUL HINTS FOR USE
 Before applying glue to a surface or workpiece, use a
scrap piece of paper or material that is similar to your
workpiece as a test.
 Use caution when applying hot glue to thin or porous ma-
terial. The underlying surface could be damaged or glue
could adhere to the surface and be difficult to remove.
 Do not force the trigger when applying hot glue. This
could damage the glue gun. Use a test piece of material
to make sure the glue has melted enough to flow without
forcing.
 Apply only as much glue as needed for your application.
 When gluing two objects together, do not pick up the
object to which hot glue has been applied. Instead, pick
up the other object and join it to the object to which you
have applied hot glue.
 Do not use your fingers to press down on an object to
which hot glue has just been applied. This can cause hot
glue to escape from the edges or heat up the bonding
surface and possibly cause burns or damage to surround-
ing objects.
 Allow glue to dry completely before moving your work to
ensure proper adhesion and reduce the risk of burns.
 If applying glue to very small objects, use tweezers or
tongs to avoid getting the nozzle close to your fingers.
APPLYING HOT GLUE
See Figure 4, page 9.
WARNING:
To reduce the risk of injury, the glue gun should be con-
sidered to be HOT whenever the LED on the unit is illu-
minated. Following this rule will reduce the risk of burns,
fire, or serious personal injury.
 Install the battery pack and turn the on/off switch to the
on (I) position.
 Allow time for the glue to melt so that it flows freely from
the nozzle.
 Hold the glue gun firmly, as shown in figure 4. Place the
nozzle close to the surface where glue will be applied.
NOTE: Holding the glue gun too far from the intended
surface may result in applying glue to a surface other than
your workpiece or may result in "strings" of glue between
your work and the nozzle.
 Pull the trigger until glue flows from the nozzle. Do not
over-apply.
NOTE: For better control and consistency of application,
it is advisable to use two fingers to pull the trigger.
