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 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.
