INSTALLATION
11. Operate shutter by pressing right side of foot switch. With the timer switch in the
manual position, the shutter operates directly from the foot switch. In the timed
position, the shutter opening is determined by the setting of the potentiometer;
clockwise increases the opening time and the foot switch must be released after
each cycle.
12. Set air pressure regulator to 10-15 psi on air gauge.
13. Place a syringe of adhesive with follower plug installed in manifold and install
syringe adapter. Install desired needle. Snug set screw to retain syringe in
manifold.
14. Install light guide in manifold and snug set screw to hold in place. DO NOT
OVERTIGHTEN.
15. Select dispenser timer switch to desired position.
16. Depress foot switch to left to dispense adhesive. Adjust air pressure and time to
dispense correct amount. Increase air pressure and time to dispense more adhesive
and decrease to dispense less adhesive. Experimentation is the best way to
determine correct settings and needle size to dispense correct amount of adhesive.
Excessive dripping or oozing of adhesive from the needle indicates air is entrained in
the adhesive or more vacuum suckback is needed.
17. Adjust vacuum suckback to prevent drips should they occur. Turning knob
counterclockwise increases air flow to transducer which increases vacuum. A
minimum vacuum setting is usually all that is required. Care should be taken not to
use too high a vacuum, since this will suck adhesive up the air line into the solenoid
valve.
