Thank you for your question, Jim M! To remove the temperature knob cover, its easiest to pry off the cover on the side opposite the lever. Once the cover is removed, you will need to also remove the Phillips head screw that holds the knob on to access the Rotational limit stop. Information on adjusting the temperature can be found on page, 7 step 4 below.
Best regards, Edward
