8. Avoid turning barrels upside down or laying barrel, so that material may run through the vacuum
line to the internal components.
9. Do not allow the barrel assemblies to contact hot or sharp objects.
10. Avoid exposing the liquid dispenser to excessive moisture or solvent situations.
NOTE: Dispose of all tips and barrels after use. Always use new tips and barrels to prevent
contamination, insure cleanliness and provide consistent, repeatable material deposition.
Tip Selection
Selection of the proper tip for the application is essential to obtain the optimum deposition rate and
amount. Check the specifications of the material manufacturer for recommended tip sizing. The tip size
and duration of the dispense cycle determine amount of material deposition (dot or bead size). Dispense
several dots (or beads) onto a piece of paper or scrap PC board to check for desired results.
Corrective Maintenance
Most malfunctions are simple and easy to correct.

Solution
Replace fuse.
Unplug from wall, remove top cover, and visually
inspect for any loose or shorted connection.
Check the facility breaker/wiring.
Replace power switch.
Check foot switch (or finger switch) connection.
Unplug from wall, remove top cover and check for
loose connection.
Check air supply and pressure gauge. Reset the
regulator if necessary, remove barrel from
adapter. Depress foot switch (or finger switch) to
check airflow.
Clean or replace solenoid as necessary.
Verify AC receptacle voltage.
Check air supply and pressure gauge.
Clean or replace solenoid as necessary.
Verify the rating of the fuse.
Unplug power input, remove cover, and check
