3.6 Bleeding the nozzle air
To optimize the pressure in a syringe, the air in the nozzle must be bled out.
Use the following procedure to dispense adhesive from the head to bleed the air. Do this just before starting
production.
c
CAUTION
When temperature setting is used, allow at least 15 minutes after installing the syringe before bleeding the air so that
the temperature of the temperature regulator unit is sufficiently transmitted to the syringe.

2. Place a rag beneath the head and press the [Blow] button for the applicable head.
3. Check that the adhesive is dispensed smoothly.
• After replacing the head or syringe, blow for a period long enough to bleed the air.
• Nozzles for Type111, 112, 114 will dispense adhesive 10 centimeters or more from the nozzle tip.
• Nozzles with large diameter holes other than the above will dispense adhesive approximately 5
centimeters from the nozzle tip.
