Thank you for your question, Wally! To remove the handle, first pop off the red and blue button, then use a 1/8" Allen wrench to loosen the set screw and pull off the handle. Please be sure to turn off the hot and cold water supplies if you disassemble the faucet any further. Please also refer to page 4 of the Installation Instructions for a diagram.
Best regards, Jon
