You got the extension wings too? Make sure that you carefully align their clamps and tighten them well, otherwise the extensions wobble all over the place. Use care when folding the saw down to the travel position, and good luck getting the extensions back into the plastic end cap holders, I cant figure that out! Also, use care when attaching the clamps to the bottom of the Kapex saw itself before attaching it to the UG cart, I was doing mine on a table and the saw fell on the floor! OOPS!
Happy cutting.
