Cleaning and Maintenance
Proceed as follows:
Remove the PUR cartridge from the
applicator.
Unscrew the nozzle adapter from
the warm glue cartridge.
Use a pointed tool to open the outlet of
the PURcleaner cartridge.
Screw the nozzle adapter on the
screw thread of the cleaner cartridge.
Insert the cleaner cartridge in the
applicator. Please ask the glue
producer for the cleaning agent
suited for the glue used by you.
Allow about 20 minutes for the
applicator to warm up the cleaner.
Flush the nozzle adapter with
cleaner until you see cleaning
agent come out steadily.
Remove the cleaner cartridge from the applicator and
unscrew the nozzle adapter and nozzle from the cleaner
cartridge while it is still warm.
Caution: Hot cleaning agent may flow out!
Allow the cleaner cartridge to cool and keep it for further
use.
The applicator is to be maintained by skilled personnel
on a regular basis. The frequency of maintainance
depends on wear and the hotmelt in use.
Never fill soiled glue into the melting tank. The heating
temperature should be lowered during longer work
breaks to preserve the hotmelt. Ongoing heating makes
the hotmelt coke and may also change its'
characteristics. If you follow all advices given in the
operating manual, the glue applicator does normally not
need cleaning. The nonreactive glue contained in the
applicator will remelt and can be used for glueing again.
The working temperature of the respective glue may be
taken from the technical datasheet which can be
procured from the producer of the glue. This temperature
must not be exceeded, otherwise the glue may coke in
the glue applicator. Hotmelts on a polyamide basis are
particularly sensitive. If the glue has coked, the applicator
should be cleaned. If a special cleaning agent is needed,
information on this cleaning agent is available at your
glue supplier.
Never clean the applicator with solvent, benzine,
benzene, toluene, acetone, turpentine, etc. risk of
explosion!
When reactive PUR hotmelt glues are used, the adapter
and the nozzles must be flushed thoroughly. For this, use
a special cleaning agent in 310ml cartridges. Please ask
your glue supplier for the cleaning agent suited for the
hotmelt used by you.
Cleaning the Nozzle/Nozzle
Adapter after having
applied PUR Hot-Melt Cartridges
(TR 700 / 70 / 80)
Warning: risk of burns!
For your own safety you are advised
to wear protective gloves and safety
goggles when replacing nozzles.
When the applicator will not be used for a longer time,
we recommend that you clean the nozzle/the adapter
because reactive PUR hotmelts may harden within a
short time and cannot melt any more.
