Operating Instructions
Prior to using the DispenseJet for production runs, it is recommended that you conduct a brief test-run to
verify that adjustments and parameters are set for optimum performance.
NOTE Read the entire section before operating the DispenseJet. The sequence of events may vary
with your particular application.
CAUTION! Operation of the DispenseJet should be performed only by Nordson ASYMTEK-
trained operators or service technicians, or Nordson ASYMTEK field service
engineers.
Tools and Material Needed
• Adjustment and assembly tools
• Nozzle kit
• Appropriate solvent and containers for the selected dispensing fluids
• Personal protective equipment
DispenseJet Setup Adjustments
There are two pre-requisite minor adjustments that must be performed on the DispenseJet (see Figure 4-2):
• Preload setting
• Micro-adjustment setting
NOTE For major adjustments, you need to remove and disassemble the DispenseJet. It is best to
make major adjustments before installing the DispenseJet to the dispensing system. See
“Settings and Adjustments” in the Maintenance and Service section in this manual.
Setting the Preload
To set the DispenseJet Preload:
1. Back off the micro-adjustment by turning it counterclockwise.
2. Count the number of times you completely turn the preload screw downward from its current
position to regulate the desired space for the preload setting.
TIP It is best to determine the smallest dot or line to be dispensed before you set the
preload. Typically, too little tension or too much tension will result in poor
dispensing results.
3. Twist the preload lock nut all the way up on the preload screw so that it rests against the cap.
4. Using the kit-provided spanner wrench, turn the preload lock nut until it stops.
