Spray Pattern Problems Remedies
Fluttering
1. Air enters between fluid nozzle and tapered seat of spray gun body.
2. Air is drawn from fluid needle packing set.
3. Air enters at fluid container fitting nut or fluid hose joint. 1. Remove fluid nozzle to clean seat. If it is damaged, replace nozzle.
2. Tighten fluid needle packing.
3. Fully tighten joint section.
Crescent
1. Paint buildup on air cap assy. partially clogs horn holes.
Air pressure from both horns differs.
1. Remove obstructions from horn holes with attached brush.
But do not use metal objects to clean horn holes.
Inclined
1. Paint buildup or damage on fluid nozzle circumference and air cap
assy. center.
2. Fluid nozzle is not properly fitted.
1. Remove obstructions.
Replace if damaged.
2. Remove fluid nozzle and clean seat section.
Split
1. Liquid temperature of paintis low(especially caution in winter).
2. The paint is oxidized.
3. Fluid output too high.
4. Pattern air pressure is too high.
1. Add paint to increase viscosity.
2. Turn fluid adj. knob clockwise to reduce fluid output.
3. Turn pattern adj. assy. clockwise to reduce pattern air pressure.
Heavy Center
1. Liquid temperature of paint is low (especially caution in winter).
2. The paint is oxidized.
3. Fluid output is too low.
1. Add thinner to reduce viscosity.
2. Turn fluid adj. knob counter-clockwise to increase fluid output.
Spit
1. Paint buildup on fluid nozzle circumference and air cap assy. center.
2. Fluid nozzle and fluid needle are not seated properly.
3. The first-stage travel of trigger (when only air discharges) decreases.
4. Paint buildup inside air cap assy. 1. Clean the nozzle and air cap regularly.
2. Clean or replace fluid nozzle and fluid needle assy..
3. Replace fluid nozzle and fluid needle assy.
4. Clean air cap assy.

■ How to operate
・
Suggested air pressure is 2.5 to 3.9 bar (36 to 57 PSI).
・
Recommended paint viscosity differs according to paints property and painting conditions.
・
Keep fluid output as small as possible to the extent that the job will not be hindered.
It will lead to better finishing with fine atomization.
・
Set the spray distance from the spray gun to the work piece as near as possible within the range of 200~250 mm (7.9~9.8 in).
・
The spray gun should be held so that it is perpendicular to the surface of the work piece at all times.
Then, the spray gun should move in a straight and horizontal line. Arcing the spray gun causes uneven painting.
