5.5 Demounting and Cleaning the Nozzle
ADVICE
Heed all security advices given in chapter 5.1.
1. Stop adhesive supply/ all motors.
2. Switch the unit voltage-free and pressureless!
3. Guard the unit against unauthorized restarting.
4. Place a heat-resistant catchment container/underlay under the Applicator. Hot
adhesive may come out!
5. Open the application module by activating the
solenoid valve’s manual trigger. Thus, adhesive
will come out of the nozzle and the system
pressure will be relieved.
6. Unscrew the nozzle’s cap nut (1) from the
application module using a SW19 wrench and
remove it with nozzle (2).
7. Clean the nozzle boring with nozzle cleaning tools
from ITW Dynatec.
8. Assemble the nozzle in reverse order.
After finishing the maintenance or repair works:
Remove all materials and tools used during the
repair or maintenance from the workspace of the
unit.
Connect the voltage supply and the compressed
air supply. Heat the unit up. Wait until all
temperatures are within the tolerances and the
adhesive in the tank is molten completely.
CAUTION
Before each start of production, purge the
Applicator,
i.e. let the adhesive flow out until
the adhesive is clean and bubble free.
Thereafter switch off the adhesive and clean
the nozzle from adhesive.
Continue production.
