New design. One piece semi rigid cover for speed control and distance buttons on T2 models.
Remove all existing cover and grey buttons, leaving just the plastic moulding.
Thoroughly clean area using lighter fluid, WD40 etc.
Simply replace 2 grey buttons (supplied) by removing backing paper. Once applied, remove the backing paper on the top of the button.
Remove backing paper from the "Moon" shape cover and align over handle. Make sure you align the first time, as adhesion is very strong.
Press down on all areas of cover to form good fit.
