Tools Required: Phillip's head screwdriver, flat-head screwdriver, pliers (optional).

• With the battery taken out of your sprayer, take your screwdriver, unscrew the cover plate and set aside.
• Unscrew the strain relief fitting.
• Taking your fingers or the pliers, gently remove the circuit board connections from the power switch. The connections should come off easily when squeezing the translucent clips.
• Using a flat-head screwdriver, hold down on the tabs on the power switch and pop it out from the sprayer housing.
• Carefully, push the replacement pressure switch in its place.
• Reconnect the red, white, and black wires of the circuit board to the new power switch.
• Place a battery in the battery slot and turn the sprayer on. Ensure the sprayer operates on both pressure settings by flipping the pressure switch.
• If the sprayer is functional, replace the cover plate and secure with screws.
