knob set at minimum setting does not supply
power to unit).
4. Faulty or loose wiring.
5. Excessive motor temperature.
6. ON/OFF switch is defective.
1. The PRIME/SPRAY valve is in the SPRAY
position.
2. Air leak in the siphon tube/siphon assembly.
3. The pump filter and/or inlet screen is clogged.
4. The siphon tube/siphon assembly is clogged.
1. The spray tip is worn.
2. The spray tip is too large.
3. The pressure control knob is not set properly.
4. The pump filter, gun filter, or inlet screen is
clogged.
5. Material flows from the return hose when the
PRIME/SPRAY valve is in the SPRAY position.
6. Air leak in the siphon tube/siphon assembly.
7. There is external fluid leak.
8. There is an internal fluid section leak
(packings are worn and/or dirty, valve balls
are worn).
9. Worn valve seats
10. Motor powers but fails to rotate
1. The upper packings are worn.
2. The piston rod is worn.
1. Wrong type of airless spray hose.
2. The spray tip worn or too large.
3. Excessive pressure.
