Use sharp blades and learn how to set and change them (you have the manual? It is necessary. Oh, and read it!). If you have a Tormek sharpener, the planer blade grinding jig is expensive but good, and saves money over buying new blades after a few sharpenings.
Keep it clean, vacuum up wood bits off the threaded rods.
I find the WD40 + Teflon spray good for lubricating this and other woodwork machinery.
EITHER get a high volume chip collector (I use a Camvac) OR spray the chips all over the floor and sweep up after. A a normal ship vac will get backed up in no time and ruin the surface.
Make sure there are no nails in the work!
And enjoy. They are good machines, and mine has given me good hobby-level service for over ten years. And much of what I plane is hard teak floorboards.
