change the nozzle when glue is
cold. To change the nozzle, the
gun must be heated until the glue
is softened enough to remove
the nozzle (about 1 minute). Use
gloves and remove the old nozzle.
Flush glue through the gun, to
clean out the melting chamber.
Replace with a new nozzle. Tight-
en only until snug. Do not over
tighten.
• Keep outside of glue gun clean.
• Do not use glues other than those
recommended by Rapid
• Leaving the tool switched on for
too long without use can lead to
risks. Unnecessary overheating
over a long period of inactivity,
without use, depending on the
length of time and type of glue
used, can have adverse effects:
* Melting and softening of the
glue stick at the back of the tool,
or even adhesion of the stick in
the back entrance sleeve at the
entrance of the heater. In this
case, restarting your tool for
subsequent operation may take
longer and be more diffi cult.
In the event of such a problem,
Rapid recommends that you
follow these steps:
- Plug in the tool and leave it
heating for around fifteen min-
utes.
- Start to push the glue by
pressing lightly on the trigger
from time to time. Contin-
ue to let the tool warm up
and repeat this action until
it unblocks. The unblocking
time may be longer or shorter
depending on: The type and
6
composition of the glue that
would have been used and
the duration for which the
tool has been left heating up
unnecessarily, without being
used for gluing.
If start-up is still difficult after
this action:
- Remove the nozzle, beware
with the device being hot.
- Place the tool on its stand.
Leave it plugged in and heat-
ed.
- Purge the tool by letting the
hot glue flow out under gravi-
ty, onto a disposable support
(container, paper, card-
board,..).
- Start to push the glue by
pressing lightly on the trigger
from time to time. Continue
to let the tool warm up and
repeat this action until it un-
blocks. Pull the trigger a few
times, to make sure that the
old glue has been completely
cleared and the tool has been
completely purged.
* Charring of the glue, depending
on the nature and composi-
tion of the glue used, occurs
when the glue remains molten,
trapped inside the tool, for too
long. Once charred, the glue
will begin to obstruct the nozzle
and thus lead to a glue leakage
of glue towards the back of the
tool which in the long-term can
be serious consequences such
as a system blockage at the
front or a break in the heating
system.
In this event:
