  1. Disconnect power supply (battery / cable) and turn the spray / prime nub down to the prime position
  2. Remove the cup assembly
  3. Remove the tip guard assembly and turn the prime / spray nub forward to the spray position
  4. Remove the cross-head screw from the prime / pump spray nub and remove the nub
  5. Remove the seven cross-head screws from the sprayer enclosure and remove the enclosure cover
  6. Carefully remove the pump assembly from the enclosure (on the Graco UltraMax you will have to remove the static dissipation wire first – and save the screw!)
  7. Place the new pump assembly into the Smart Control housing – DO NOT REMOVE THE YELLOW LOCKING DEVICE! (on Graco UltraMax models you will have to reinstall the static dissipation wire) 
  8. Push the pump assembly down into the SmartControl enclosure – the pump locking device will snap away from the pump assembly
  9. Install the enclosure cover and install the cross-head screws, making sure the wires are not pinched. See the manual for correct torque specifications
