How to remove Amalfi handle?

For Kitchen and Single Handle Lavatory faucets:

Pull out the rubber button (part #1).
Use a hex wrench (part #4) to unscrew the handle set screw (part #2).
The hex wrench is 2.5 mm head or 1/8".
Unscrew counter-clockwise to loosen the set screw.
Then pull out the handle (part #3).
If still hard to be pulled away, loosen the set screw again counter-clockwise.

For Two Handle Centerset Lavatory & Roman Tub Faucets:

Remove the top cap (part # 1)
Unscrew the set screw (part # 2) counter-clockwise using Philips or a flat screwdriver.
Then pull out the handle.

For Trim Line - Mini Widespread faucets:

Turn the water off under the sink (hot and cold supply lines).
Support the handle valve body under the sink. The handle valve body will fall off when the handle is removed.
Turn the handle ring (part #1) counter-clockwise by hand till the handle is out completely. If you are unable to remove it by hand, you can put a cloth around the ring and use a pair of pliers or an adjustable wrench to remove it.

For Showers:

Hold the lever handle (part #1) at the OFF position (facing down like in the picture above).
Unscrew the handle body (part # 2) counter-clockwise by hand.
Unscrew the handle trim ring (part #3) counter-clockwise by hand.

For the Diverter handle on the escutcheon plate:

The diverter handle is secured to the escutcheon plate with a C-clip. To remove it, you will need to remove the volume control handle, the handle trim ring and the escutcheon plate from the shower valve first.
Once removed, use two small, flat-bladed screwdrivers to aid in the removal of the C-clip.
On the back of the escutcheon, use one screwdriver blade at one end of the C-clip to keep it from turning and use the other screwdriver blade to push the C-clip end down and out of the groove.
With the C-clip removed, be careful to retain the rubber O-ring and metal washer which were under the C-clip.
Remove the diverter handle and retain the small black plastic washer which is found on the handle.

For 1/2" Diverter Valve or 3/4" Volume Control Valve:

While holding the lever handle at the OFF position (facing down like in the picture above), unscrew the handle body (part #1) counter-clockwise by hand.
Use an adjustable wrench to grab onto the flat on each side of the handle adapter assembly (part #2) and unscrew it counter-clockwise to remove it.
Remove the escutcheon plate (part #3) to reach the rough-in valve.
