Troubleshooting Chart
Symptom
Motor hums and does not
run
Motor does not run or hum
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 on pages 7-
11)
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
Possible Cause(s)
1. Unit under pressure
2. Equipment has been dropped
which caused motor to become
misaligned
3. Supply voltage too low
4. Power Switch is in OFF position
5. Bad power connection
6. Circuit breaker or fuse is tripped
7. Thermal overload protection
activated
8. Check valves stuck
9. Suction Assembly loose and/or
sealing surfaces are dirty at Inlet
Valve
10. Suction Head not immersed in
paint
11. Prime/Spray Control is in the
spray position and/or the
Pressure Control is in the Low
Pressure/Hydraulic Bleeding
position
12. Hydraulic system contains air
13. Hydraulic oil level low
14. See Possible Causes 9,10,11,13
15. Clogged suction filter
16. Trash caught in valves
17. Paint sediments settled to
bottom of bucket
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 By-Pass Tube.
Prime/Spray Control is worn or
damaged
Corrective Action
1. Turn Prime/Spray Control to prime position
2. Take to authorized service center to have motor assembly
realigned. Or, call technical support
3. Do not use an extension cord, it is better to add hose length.
Use portable generator with a 2400 VA minimum rating
4. Flip Power Switch to ON position
5. Check power connections at power receptacle, along extension
cord and at equipment for looseness or damage
6. Correct cause of circuit overload. (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 due to droppage)
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 due to droppage)
8. "Pop" Inlet Valve and Outlet Valves. See step 5 of Preparation
instructions
9. Remove Suction Assembly, clean sealing surfaces and reassemble
10. Add more paint to bucket and/or adjust position of Suction
Assembly
11. Turn the Prime/Spray Control to the Prime position and Pressure
Control fully clockwise
12. Turn Pressure Control to Low Pressure/Hydraulic Bleeding
position for 1 minute while motor is running
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
14. See Corrective Actions 9,10,11,13
15. Remove suction filter with pliers and clean. Also, refer to
Maintenance section
16. See "Force Feeding" figure on page 18
17. Strain and mix paint thoroughly
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
