I recently got a Dewalt 735 (as I believe many people have) and seem to be having issues with the dust port. It seems to get clogged every time I pass a piece of wood through it, both at the planer end and/or at the dust collector end. I don’t feel like I’m taking a ton off of the wood when I make a pass, Less than 1/16 according to the gauge.

I must be doing something wrong, otherwise I’m sure this would be a very common complaint.

I ran some pine through mine, and it clogged, seemed the moisture content was high, I can’t remember exactly its been awhile. I ended up opening the unit and finding this area filled w/ chips

I have never had mine clog…the little motor and fan set up in this planer is pretty powerful. If I turn mine on without the dust collector hooked up and hold my hand in the way of the discharge it is very strong. If you turn yours on and it don’t seem to be blowing air very hard I would bet you have something blocking it. There is a thread on here that shows how to take it apart. Mine blows hard enough that I almost cannot hold my hand over the discharge port when it is on. Also, when I am planing a board the chips actually hurt when they hit my hand if I just let them blow out and stick my hand in the way. I cant imagine wood shavings of any kind not getting completely blasted out no matter how much moisture or what type of wood….gotta have an obstruction somewhere.

I’ll have to try it with the hose off and see how it feels. But it seems to me the chips just get caught up on the dust port attachment that came with the planer. It has some plastic pieces on the inside edge of the attachment, similar in configuration to crosshairs. I don’t know why they’re there, but suspect they are holding back the chips and causing clogging.

It also tends to clog at the collector end, but that could be due to the cheap HF collector I have. Both end get clogged.

Could you post a picture of the outlet and crosshairs? It might give us a better idea of what’s happening and possible solutions.

Take the top cover off as if you were changing the blades and see if anything is clogged inside. My 735 inflates the bag in my DC when the DC is turned off. The blower is very powerful.

The only time mine has clogged was from planing wet wood, like cedar.

Have your say...
