24. Remove Suction Filter and clean. Also, refer to Maintenance 

section

25. Suction Assembly loose and/or 

sealing surfaces are dirty at Inlet 

Valve

25. Remove Suction Assembly, clean sealing surfaces and 

reassemble hand tight

26. Paint thick due to cold weather. 

This problem usually occurs with 

Latex based coatings

26. Do not paint Latex coatings in temperatures less than 50°F 

(10°C). Refer to paint manufactures minimum painting 

temperature recommendations

27. Inlet Valve and/or Outlet Valve 

are worn

27. Replace valves. Also, refer to Maintenance section

Gun will not shut-off

28. Trash caught in Gun Valve

28. Clean or replace Gun valve. Also, refer to Gun Maintenance 

section. This is a very rare occurrence, and will not occur if filters 

are properly maintained

29. Worn Gun Valve

29. Replace Gun valve. Also, refer to Gun Maintenance section

30. Dried paint under gun actuator

30. Remove 1/4” nut and gun actuator at rear of gun. Remove 

dried paint from around needle and back of actuator. Replace 

actuator and 1/4” nut. Set gun trigger position with trigger 

lock in locked orientation (tabs horizontal) by the following 

instructions: With one hand holding trigger softly against 

lock, use a 1/4” nut driver to turn nut in until trigger starts to 

come off the lock, then back off the nut (counterclockwise) 1/2 

turn. Pulling the trigger must not open the gun valve when 

trigger lock is activated. You should be able to get the actuator 

to wiggle slightly with your finger while holding the trigger 

against the locked trigger lock.

After moving equipment or 

adding paint to bucket, unit 

will not prime or spray

31. Suction assembly loose or 

damaged

31. Tighten suction assembly onto inlet valve. Re-prime sprayer. If 

problem is not remedied, consult Technical Support

Oil in Paint

32. Oil is leaking from between 

Block and Hydraulic Housing

32. Check hydraulic oil level. Add hydraulic oil if necessary (it is 

recommended that this be done by a qualified technician). 

Check block bolt torque

33. Diaphragm is damaged

33. New diaphragm assembly is needed. (It is recommended that 

this be done by a qualified technician.) Refer to Maintenance 

Chart concerning torque settings and type of tools required 

to reassemble block onto housing. Refill piston with hydraulic 

oil. Correct assembly of internal check valve under diaphragm 

assembly is critical to proper operation of the pump – refer to 

Parts List or contact technical Support

Fluid leaks other than oil

34. Loose connection

34. Clean sealing surface and reassemble per assembly instructions

35. Contaminated sealing surface

35. Consult technical support

36. Damaged component

36. Consult technical support

Symptoms not listed
