Topic tags/keywords: dw735 planer plane

I recently replaced the rear roller on my DW 735 planer. Of course I had to raise the cutter as far as I could in order to get the needed clearance to do the work. I was careful not to raise it so high as to have it come off the corner posts. The roller change went well but now the head won’t come back down. I still have 10-12 revolutions before it reaches it’s maximum height but it will come down those 10-12 revs and stops. It won’t come down any further. I’ve checked the chain to make sure their are no obstructions. I even removed the worm gear and made sure it is in good condition. There was no reason for me to interfere with the height adjustment when changing the roller. So I just don’t know what would cause it to stick. It will go up but it won’t come back down so it’s sitting in the up position about 8” high. Can anyone help???? Thanks James

Have you had any success figuring out the problem? I looked at my DW735 and raised it all the way up and down to see if there was anything that was obvious that could hang up but short of taking the planer apart I didn’t see anything. So you didn’t take apart any of the upper housing to remove the roller? The roller can be removed completely from below?

I did disassemble the entire upper part so I could see the chain and anything else that could have been causting it to bind but to no avail. I just don’t know what could be causing it to bind. It will still go up and down but above where it binds.

Doesn’t it have an auto depth lock? Try taking the roller out and putting it back in. See if it is getting caught. Put the original back and see if works.

I’m not sure what you mean by auto depth “lock”. I can set it as low as 1/8”. I’m going to tear it down again and check everything including the height adjustment knob that controls the depth of cut. Maybe there’s something in there. Thanks

I’m sure you looked at all the screw post to make sure there is not a piece of debris stuck in a thread. I looked at the parts diagram and I can’t come up with anything that may cause the problem short of a misaligned part.

Does it just stop going down as if it hits on something or does it gradually get tighter going down until you can’t turn the crank?

I rechecked everything again last night and no change. The thing is sitting about 8” in the up position. It will go up further and come back down but only to the same point. It comes to a sudden stop. It just won’t crank anymore. I even took the chain off but it still does the same thing. Iv’e checked all the posts for debris, cleaned the chain and sprockets and checked the worm gear for marks and grindings but all are clear. I even took the control knob off that sets the depth of cut but it seems to be working fine as it doesn’t hang up in any position.

I know nothing but try this. If it doesn’t do any good you have lost nothing and I join the others that haven’t been able to help you.

Raise it up a bit then set your depth of cut to its lowest level and try again. I know…but try it. larry

The bold sentence makes me wonder:
  1. Isn’t the maximum height 6”?
  2. Can you tell if the resistance is coming from one of the posts, and if so, which one?
  3. Isn’t this the situation in which one is advised to contact a medical professional? (sorry, could not resist)

Good luck.

I took off the top of my DW735 and watched how the sprockets and chain drive operate as cranking and I see no connection to the minimum bottom stops so I don’t see how the bottom stop can be the problem. The raising and lowering is a very simple chain drive going around a screw sprocket one on each screw post where the primary sprocket is driven by a worm gear that the handle turns. There is no locking system as the planer is running because you can raise and lower it while it’s on. My feeling is that some how the sprockets have become misaligned or out of sync and are binding within a short amount of movement. I cannot see for any other reason as to why the head stops. As to the max height, it is 6 inches. To go beyond 6 inches you’d have to take the screw post top stop caps off and crank the planer head beyond the tops of the screw post. I have read that the slightest out of adjustment on the sprockets can cause raising and lowering problems.

Have your say...
