4. Blockage in "C" shaped tube
underneath cup top lid

spray gun to work piece
2. Too much spray material
coming out
3. Too much air power behind
pressure stream
4. Tip/needle assembly too large
Coating not strained/thinned
properly
N/A. This is normal and expected.
"Bleeder" type guns are set up
this way to help increase the life
of the turbine motor.
Corrective Action
1. Check air feed tube/one way air valve and air feed
connector.
2. Make sure cup is screwed on or clamped on tightly.
3. Check for damage and replace if necessary.
4. Look under cup top lid. Locate "C" shaped tube. Remove
blockage from it.
1. Move spray gun closer to work piece.
2. Decrease the amount of spray material flowing through
spray gun.
3. Reduce air power (use optional air control/texturing
device).
4. Use a smaller tip/needle assembly instead of the current
one you are using.
Thin coating more.
