2. Position the applicator assembly against the customer-supplied bracket, and then

reinstall the three M5 screws and tighten securely.

3. Remove the steel hex cap from the

NPT port in the applicator body, and then thread

an air supply line to the port. Use PTFE tape or an equivalent on the air supply line.

4. See Figure 5. Thread a muffler to the air-close port.

NOTE: Order part number 1096469 solenoid assembly with tubing to use air-close.

5. Connect the air line(s) to an independently regulated, filtered, unlubricated and controlled

air supply.

6. For heated applicators only: connect the male plugs from the heater block adapter to the

Operation

WARNING! Allow only personnel with appropriate training and

experience to operate or service the equipment. The use of

untrained or inexperienced personnel to operate or service the

equipment can result in injury, including death, to themselves and

others, and damage to the equipment.

The needle and nozzle is typically installed onto the applicator at the factory.

1. See Figure 6. Rotate the knurled needle adjustment knob

(1) clockwise until it stops.

2. Turn the adjustment knob 4−5 turns counterclockwise.

3. Apply material pressure to the applicator. Adjust the knob

until no material flows from the nozzle.

4. Apply air pressure to the applicator.

5. To adjust output pressure at the nozzle, turn the regulator adjustment screw clockwise to

increase pressure, counterclockwise to decrease pressure. Change setting on the melter

if no regulator is used.

NOTE: A change in pressure causes a change in maximum velocity and flow.

Pressure adjustments can be made with the applicator in the on or off position.

NOTE: Install a gauge into one of the

−18 inch SAE ports (4) monitor applicator

pressure.

NOTE: When using the air−close feature, adjust the air−close regulator for minimum

pressure by turning the air regulator adjustment screw counterclockwise several turns.

Make final adjustments to the air−close regulator to achieve good cut-off at the nozzle

after obtaining the material output flow rate.

The applicator is now ready for normal operation.
