Maintenance and repair work is only permitted for skilled personnel!
Always wear safety shoes, heat-resistant protective gloves, safety goggles
and protective clothing that cover all vulnerable parts of the body while
working on the heated unit! Risk of injury or severe burns!
Components and adhesive are hot. Take every precaution to prevent the
material and hot surfaces from contacting the skin.
During the purging procedure, hot adhesive can come out of the
Applicator under high pressure. Wear safety glasses, gloves and
protective clothing.
Refer to the drawing in Chapter 7 for more information.
1. Stop all motors.

instructions under Chapter 5.4 “Relieving Adhesive
Pressure”.
5. Remove the module from the service block by
removing the two mounting screws on the front of
the module with a hex key screwdriver (Allen

the back of the module are also removed (the new
module will include new O-rings).
6. Mount the new module in reverse order and attach
it to the manifold with a torque of 20-25 in./lbs (2.3-
2.8 Nm).
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
