2. For low viscosity glue you should open the vacuum switch to prevent dripping.

3. Remove the air in the glue and piston.

4. How to Use the Vacuum Control:

The vacuum control allows low viscosity liquids, even water, to be consistently dispensed without dripping

between cycles. The vacuum exerts a negative pressure on the liquid in the barrel and prevents dripping.

For these tests, you will use the test barrel with the clear fluid.

1. While holding the barrel upright in one hand, remove the orange end cap and insert the piston. Allow

an air gap as shown.

2. Attach the barrel to the adapter. Snap the safety clip tightly closed to prevent any dripping or

bubbling. Remove the tip cap and attach the tip.

3. Set air pressure and the time.

4. Press the "Man" button.

5. With the barrel pointing downward over a container,

unsnap the safety clip. Then press the foot pedal to fill the

tip.

6. If a drop begins to form at the end of the tip, slowly turn

the vacuum control knob counterclockwise to stop the

drop from growing. Wipe the tip and adjust vacuum as

necessary. Normally, only 1 to 2 psi of vacuum pressure

is necessary.

7. Press the "Auto"-button to return to the preset dispense

time.

8. Take the barrel and place the tip on the test sheet. Press

the foot pedal. Check the dot size. Increase or decrease

by adjusting pressure or time.

If you choose not to use the piston, please follow these instructions carefully:

1. While holding the barrel upright in one hand, twist on an orange tip cap. Using the small funnel, fill

about 2/3 full with your fluid.

2. Open the safety clip and attach the barrel to the adapter.

3. Close the safety clip as tight as possible.

4. Increase vacuum by turning vacuum control knob counterclockwise and set to 1.5 on the vacuum

pressure gauge.

5. Then, without tipping the barrel upside down, remove the tip cap and attach the 25 gauge (red) tip.

6. Open the safety clip. Your material may begin to bubble. Reduce vacuum by turning vacuum control

knob clockwise.

7. If a drop begins to form at the end of the tip, slowly turn the vacuum control knob counterclockwise

to stop the drop from growing. Wipe the tip and adjust vacuum as necessary.

Now the fluid is in proper balance. It does not bubble or drip.

Repeat tests as before, keeping the air pressure low and adjusting the time for different deposit sizes.

Contact Drifton service if you have any questions.

Two things to remember (if you do not use the piston when dispensing thin fluid)

1. Do not tip the barrel upside down or lay flat, this will cause the liquid to run into the dispenser.

2. When changing tips or attaching a tip cap, snap the safety clip completely closed to prevent any

dripping or bubbling.
