Hi Spectric. Exactly the same for the Jessem. You have to lock the adjuster first and then turn the disc, then unlock for in use adjustments. The little plastic disc is fairly stiff and needs good pressure from both fingers but it doesnt slip in useDoes anyone know if this also applies to the Jessem?
My procedure is once I have fitted the cutter I set the height to zero. Then zero the height wheel. Then I know all adjustments are being made from a base level
In practice if I am making a series of passes I only lock the height for the last one but I have never noticed any movement
