keep feeding mechanism and melt chamber
free from dirt and other foreign debris.
• Storeunusedgluesticksinaclean

The feed mechanism may be damaged or impaired. If
you need to change glue type, cut off the protruding
end and feed the remainder through with the new glue
stick.
• Donotlaytheheatedgunonitsside.Keeptheheated

workbench, with nozzle pointed down.

allow gun to cool, and gently remove the obstructing
glue.

attempt to 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. Tighten only until
snug. Do not over tighten.

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 difficult.
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 minutes.
- 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 unblocks.
The unblocking time may be longer or shorter
depending on: The type and 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 heated.
- Purge the tool by letting the hot glue flow out
under gravity, onto a disposable support
(container, paper, cardboard,..).
- 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 unblocks.
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
composition 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:
- Remove the nozzle, beware with the device
being hot.
- Placethetoolonitsstand.Leaveitpluggedin
and heated. Purge the tool by letting the hot glue
flow out under gravity, onto a disposable support
(container, paper, cardboard,..).
- Insert a new glue stick, pushing lightly on the
trigger.
- Pull the trigger a few times, to make sure that the
old glue has been completely cleared and the
tool has been completely purged.
- Replace the nozzle with a new one.
• Inanycase,youshouldnever:
- Force the trigger before the tool has heated up to its
working temperature
- Push hard on the glue stick, never attempt to remove
it from the back.
