Pry off the handle cap with the blade of a small standard screwdriver. The handle cap is located at the center of the handle and conceals the handle's lever retaining screw. To avoid damaging the finish of the cap or of the handle, wrap the blade of the screwdriver with a single layer of thin tape. The key to removing the handle cap is to gradually pry the cap off of the top of the handle evenly.
Remove the handle's lever retaining screw from the center of the handle.

Pull the lever retaining screw out of the handle along with the metal split washer located underneath the screw.
Lift the handle lever off of the faucet assembly to access the handle skirt.
Remove the handle skirt. The handle skirt is the base of the handle assembly and is held in place with a single Phillips-head screw. Remove the screw with a Phillips-head screwdriver, then lift the skirt off of the top of the faucet.
