Troubleshooting Chart
Symptom | Possible Cause(s) | Corrective Action |
Motor hums and does not run | 1. Unit under pressure | 1. Turn Prime/Spray Control to prime position |
2.Equipment has been dropped which caused motor to become misaligned
2.Take to authorized service center to have motor assembly realigned. Or, call technical support
| 3. | Supply voltage too low | 3. | Do not use an extension cord, it is better to add hose length. |

Motor does not run or hum | 4. | Power Switch is in OFF position | 4. | Flip Power Switch to ON position |
| 5. | Bad power connection | 5. | Check power connections at power receptacle, along extension |
|
|
|
| cord and at equipment for looseness or damage |
| 6. | Circuit breaker or fuse is tripped | 6. | Correct cause of circuit overload. (Possible causes: Supply |

|
|
|
| motor or motor has been damaged.) |
| 7. | Thermal overload protection | 7. | Allow motor to cool for approximately 30 minutes, determine |

| cause and restart motor. (Possible causes: Supply voltage too |
|
|
|
| low, extension cord too long for available supply voltage, |
equipment was under pressure while trying to start motor or motor has been damaged.)
Motor runs, but pump does not prime after being cleaned after last use. (This problem can usually be prevented by following the recommended cleaning and storage procedure)
8. Check valves stuck | 8. “Pop” Inlet Valve and Outlet Valves. See Preparation |
| Instructions |
9. Suction Assembly loose and/or | 9. Remove Suction Assembly, clean sealing surfaces and |
sealing surfaces are dirty at Inlet | reassemble |

13.Hydraulic oil level low | 13.Add oil so level is within 1/4” of housing edge. (See notes in |
| Maintenance Section on oil leaks.) Turn Pressure Control to Low |
| Pressure/Hydraulic Bleeding position for 1 minute |
Motor runs, but pump does not prime even though it was working just fine a little while ago. (Usually occurs after moving or adding more paint to the paint bucket.)

Pump primes, but does not build pressure
18.Prime/Spray Control not in Spray position
19.Pressure Control not set to high enough pressure
20.Even though Prime/Spray Control is in Spray position, fluid still flows from
18.Turn Prime/Spray Control to Spray position
19.Turn Pressure Control clockwise to desired pressure. Fully clockwise is maximum pressure
20.Replace with service kit (See replacement parts list) or take equipment to authorized service center
