Insufficient Paint

Insufficient Paint
Flow or No Flow

Flow or No Flow

1. Defective pump or inadequate air

pressure at paint pressure pot

2. Feed tube clogged

3. Paint hose clogged

4. High viscosity paint

5. Needle valve clogged

6. Solvent filter clogged

7. Gun fluid passage clogged

1. Clean the bell (see SI-03-03 "Solvent Effects

on #2 Handgun Bell / Brush Wear").

2. Position as indicated in the "Installation"

section.

3. Reposition or replace (see Figure 4).

4. Replace.

5. Check that seal is clean (clean or replace

seal). Motor shaft warped (replace motor
shaft). Also see "Electrical Troubleshooting".

6. Reduce paint delivery and/or use larger bell

(see "Specifications" in the "Introduction"
section).

7. Test paint resistance (conductivity). See

"Solvent Selection" (TL-00-02).

8. Replace bell.

9. Contact your Ransburg distributor.

1. Repair pump or increase pressure.

2. Follow "Color Change" procedures in the

"Operation" section.

3. Clean with solvent and/or air pressure.

Replace hose when required.

4. Increase fluid pressure or reduce viscosity.

Cold paint will have a higher viscosity.

5. Follow "Color Change" procedures in the

"Operation" section and/or repair valve.

6. Clean or replace filter. See "Filter Cleaning

or Replacement" in the "Maintenance"
