I have an older dewalt dw733 12 1/2" thickness planner it has started skipping and jerking when you send a board through it even with a super light pass. I cleaned the rollers and waxed the bed but it is still jumping and skipping. I checked the roller drive chains and sprockets they look good. I ran it with the cover off and the roller drive chains jump real bad when it skips but they are not skipping the sprockets. I was wondering if anyone else may have had this problem and what the solution might be. I am wondering if it might be a broken gear inside the motor.
Thanks

I had 734 that went gunny sack last spring due to my shop being drenched when a tornado took part of the roof off of the shop. The remedy was to buy a 735 which is a real improvement over the 734 model. I'm not trying to be cute though it may sound like it, I am saying that if it comes to having to buy a new planer, you wure will be happy with the 735.

Wish I could help you with the problem that you have described, you might need to get it to a Dewalt Repair Center. Let us know what you finally find out and/do with the tool.

If this is happening at regular intervals then my guess is a tooth has broken. It is also possible that a roll pin that locates a gear has failed, maybe slid part way out and is causing the jump. I think it will have to be taken apart to find the problem.

Roxanne, I suspect the drive chain has a failure in a link. I would mark the side of one link then run it to see if the jumping occurs at the same point in relation to the mark. If so the chain has a bad link or is stiff at some point. Or if the chain could be removed you could inspect each link. If a chain gets twisted it would also make it jump at regular intervals in relation to your mark. Hope this helps.

Before you do start looking at replacement parts, clean and wax the table, and then send a few test pieces through. Sometimes pitch and/or resins for the woods will coat the table, and will make it sticky rather than slippery and the planer will have trouble pulling the piece through.

Roxanne,

I just had to take my 733 to the local Dewalt service center for a similar problem. The result was that I needed a new roller (I forgot whether it was the infeed or the outfeed roller) and also a new belt.
If you are near a service center maybe they can analyze yours and give you a quote. The cost for my parts and labor was $ 105 including a new electrical cord that had a splice in it. Better than having to buy a now planer!

Good Luck,
Ken
