If you encounter a problem that you cannot readily solve, call EFD.
Trouble
Possible cause and correction
Inconsistent beads
1. Check dispensing tip, syringe barrel and material for possible clogging.
2. Check air pressure to be sure pressure is not varying. If needed, use the
filter regulator (EFD part #2000F755).
3. Air bubbles in the material can cause inconsistency. For best results,
remove all air bubbles.
Material suck-back
1. Use a SmoothFlow piston or LV Barrier to prevent material being drawn
into the dispenser.
2. Another option is to order the filter trap accessory, which prevents fluid for
leaking into the dispenser. Order EFD part #1000FLT-Y.
3. If suck-back occurs, attach an empty barrel, place the barrel in a cup,
then press the foot pedal to expel the fluid.
4. If the problem cannot be corrected, contact an EFD Fluid Application
Specialist for assistance.
Dispensers can be returned to EFD for repair.
