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.

not operate
Bad connection
Check foot switch (or finger switch) connection.
Unplug from wall, remove top cover and check for
loose connection.
Has power and
light but does
not dispense
Reduced or no airflow
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.
Voltage is low
Verify AC receptacle voltage.
Air is insufficient
Check air supply and pressure gauge.
Solenoid buzzes
Solenoid is not clean
Clean or replace solenoid as necessary.
Incorrect rated fuse
Verify the rating of the fuse.
Blowing fuse
Internal short
Unplug power input, remove cover, and check
