Troubleshooting 

16

332763A

Motor runs and pump 
strokes

1.

Prime Valve Open.

Close prime valve.

2.

Paint supply.

Refill and reprime pump.

3.

Intake strainer clogged.

Remove and clean, then reinstall.

4.

Suction hose leaking air.

Tighten nut. Check o-rings on swivel.

5.

Intake valve ball and piston ball

 

are 

seating properly.

See Pump Manual 312362. Strain paint 
before using to remove particles that could 
clog pump.

6.

Leaking around throat packing nut which 
may indicate worn or damaged pack-
ings.

See Pump Manual 312362.

7.

Pump rod damaged.

See Pump Manual 312362.

Motor runs but pump 
does not stroke

1.

Displacement pump pin damaged or 
missing.

Replace pump pin if missing. Be sure 
retaining spring is fully in groove all around 
connecting rod. See page 17, 

Displacement Pump Replacement

.

2.

Connecting rod assembly for damage.

Replace connecting rod assembly. See 
page 17, 

Displacement Pump 

Replacement

.

3.

Gears or drive housing.

Inspect drive housing assembly and gears 
for damage and replace if necessary. See 
page 19, 

Drive Housing Replacement

.

Motor is hot and runs 
intermittently

1.

Be sure ambient temperature where 
sprayer is located is not more than 
115°F (46°C) and sprayer is not located 
in direct sun.

Move sprayer to shaded, cooler area if 
possible.

2.

Motor has burned windings indicated by 
removing positive (red) brush and see-
ing burned adjacent commutator bars.

Replace motor. See page 31, 

Motor 

Replacement

.

3.

Tightness of pump packing nut. Over-
tightening tightens packings on rod, 
restricts pump action and damages 
packings.

Loosen packing nut. Check for leaking 
around throat. Replace pump packings if 
necessary. See pump manual 312362.

Sudden noise heard from 
sprayer. Change in 
motor speed or 
performance.
