Solution
1. Tighten connection.
2. Inspect and replace where neessary.
3. Check the Air-Care™ fluid level in the Automatic
Lubricator. If low, add Air-Care™ to reservoir.

Servicing section of manual.
If dust or dirt is found inside motor, check air supply for
contamination.
Solution
1. Fluid not atomizing correctly:
Increase fluid pressure. Change to smaller tip orifice
size. Reduce fluid viscosity. Reduce hose length.
Clean gun and filter(s). Reduce number of guns using
pump.
1. Same as above.
1. Clean or replace tip.
1. Inspect for suction hose leak.
2. Change to a smaller tip orifice size. Install pulsation
dampener in system or drain existing one. Reduce
number of guns using pump. Remove restrictions in
system; clean tip screen if filter is used.
1. Replace tip.
