Push in on the button near the nosepiece and turn the nosepiece counterclockwise until it pulls free from the head of the pipet aid.

Using a large philips screw driver, remove the four screws from the handle. *Note the two different sizes of screws (the smaller one will go into the neck of the Pipet Aid.)

Cut the identification sticker down the middle or pull off to allow the housing to come apart.

Pull apart the plastic housing *the charging port will most likely get stuck to the housing, simply pull off the holder.

Be aware the mid-handle buttons might fly off as they are spring loaded! Secure these by taping to the back of the housing before completely pulling it apart.
