Tools Required: Phillip's head screwdriver, flat-head screwdriver, hot water, knife.
- With the battery taken out of your sprayer, take your screwdriver and loosen the screws holding the cover plate in place. Unscrew the strain relief fitting and set the cover plate aside.
- Locate the hose clamps securing the hoses to the pump barbs. Using a flathead screwdriver, loosen both hose clamps. Gently maneuver the outlet hose off of the pump barb and remove it. The jumper hose will be detached later.
- At this point, you may want to detach the circuit board from the cover plate to give yourself more room to work. Using a knife, slice the protective tape around the connection and disconnect the circuit board using your fingers.
- Take the phillip's head screwdriver and loosen the four screws holding the pump to the tank. You should find the pump-to-circuit board connection underneath the pump. Again, take your knife and slice the protective tape. Then, use your fingers to disconnect the circuit board from the pump.
- Firmly grip the pump and wriggle it off of the jumper hose.
- Connect the replacement pump by following the directions in reverse: slide the jumper hose onto the pump barb, connect the circuit board, and secure the pump to the tank.
- To re-connect the outlet hose, it may be helpful to dip the end of the hose in a cup of hot water for 10-15 seconds. This allows the material to soften. Slide the hose clamp onto the outlet hose and slip it back onto the pump barb.
- Tighten both hose clamps over the pump barbs with the flathead screwdriver.
- With a little bit of water in the tank, place a battery into the holster and turn your sprayer on to test it. Take note of any leaking around the pump connections. If there is leaking present, tighten the hose clamps further.
- If everything is working properly, slide the circuit board back into its slot on the cover plate and secure the cover plate back onto the tank.
