Good chip/dust collection is important. If you don't have it, chips build up on the rollers and boards won't feed well and in opinion increase the likely hood of snipe. I have a Delta planner, it has been a good one as long and I keep sharp blades in it and keep it as clean as possible. After several uses I will tear mind down and vacuum, brush and wipe as clean as possible, everything I can get to. My manual even says take the rollers out and wash them periodically. I have not done that because I have not been able to figure out how to get the completely out of the machine!! But I do clean then. Between each use I will at a minimum take a brush and brush off all the chips that may be stuck to the rollers.. Brush, switch on so roller roll a little, off, brush again.....
I think one of the biggest mistakes user make is trying to make quick work of planning. As mentioned, light passes.... and wear hearing protection!
