I've had problems with my DeWalt 734 planer rollers slipping (See thread Planer Rollers Not Gripping
), so today I tore down the planer and fully cleaned everything and re-lubricated / re-waxed surfaces. This solved my problem. Below are details and associated photos for tearing down a DeWalt 734 planer. Enjoy.
1. Remove the dust port/chute
2. Remove the height adjustment handle
3. Remove the side panels (small screws near the top of each panel)
4. Remove the top panel (hex bolts in corners)
5. Remove the roller chain panel cover
6. Thoroughly clean all cogs, chain links, crevices, etc. I used a small awl to help scrape out all bits of wood dust/shavings
7. Repeat the thorough cleaning on the drivebelt side of the planer
8. Lubricate all moving parts (I chucked a drill to the height shaft to expedite the lubrication/spreading process)
9. Clean the rollers with denatured alcohol.
10. Wax all table surfaces with paste wax and buff smooth.
Assembly is reverse of tear-down.
