Troubleshooting a Wagner Power Sprayer Assembly

Motor Problems

• 1

  Turn on the sprayer and pull the trigger.

• 2

  Check to see if the sprayer motor operates. If the motor does not run, check the plug and power outlet. If no problems exist with the electricity to the sprayer, the motor is defective.

• 3

  Listen to the motor. If it hums, but does not spray the control knob may be turned in too far. Turn the control knob counterclockwise. If that does not fix the problem, disassemble the sprayer and clean it.

Motor Works but Sprayer Does Not

• 4

  Thin the paint mixture and try holding the sprayer below the level of the attached paint can. Next oil the intake opening. This should solve problems caused by failing to prime the sprayer.

• 5

  Adjust or replace the suction valve it is damaged.

• 6

  Clean or replace the atomizer valve, if necessary.

• 7

  Clean the spray tip it is dirty or clogged.

• 8

  Adjust the control knob if necessary.

• 9

  Clean and oil the sprayer's piston or replace it if it is damaged.

Paint Sprays Improperly

• 10

  Refill the paint container if it is low.

• 11

  Thin the paint if it is too thick.

• 12

  Replace the atomizer valve it is worn.

• 13

  Replace the spray tip if it is worn.

• 14

  Adjust the control knob if needed.

• 15

  Clean and oil the piston, or replace it if it is worn.

Motor Overheats

• 16

  Clean the piston. It may be seized.

• 17

  Use a shorter extension cord. Too long of an extension cord can cause the motor to overheat.

• 18

  Release the trigger at the end of each painting pass. Continuous operation can cause overheating.

Paint Leaks Near the Spray Tip

• 19

  Tighten the spray tip if it is loose.

• 20

  Reposition the atomizer valve if it is installed incorrectly.

• 21

  Replace the pump housing if it is excessively worn and causing leakage.
