partially or bleed valve is worn. Lower
packing seat is worn.
2. Upper and/or lower ball not seating
1. Spray tip is worn
2. Outlet lter or gun lter is clogged
3. Low voltage and/or inadequate amperage
4. Hose size or length is too small or too long
1. Solvent has caused upper packing to swell
SOLUTION

2. Disassemble and clean.
3. Inspect and adjust.
4. Inspect and replace.
1. Replace.
