I have had my TP1300 for a couple of years now but have just started to use it on a reguler bases. and I am having problems with the feed rollers not coming in contact with the board to be planed unless I am making at least a 3/32 cut. If I am taking any less of a cut just barly touch the board, not enought to even hold the board down, this causes a roller coaster effect in the cut, and I am having to push the board threw. I have cleaned the rollers, took the side covers off looked for ajustments there are none. Changed the blades, Waxed the bed about 4 times, keep: the sawdust cleaned out. Please help what am I missing.
