I have just bought a new DeWalt DW734 planer. I installed the belt just as the manual says. But when I turn it on the belt just flies off. Is there a way to tension the belt or did I get the wrong one?
Thank you in advance.

Why in the world would you need to install a belt on a new planer?

Assuming to bought the planer at a local store, I would take the planer to the folks you bought it from and ask them to set it up for you.

D_Allen – Because it did not come with the belt installed. There were 2 in a plastic bag.
Docholladay – You really think anyone at Home Depot would know how to do this?

Thanks to both of you for your time.

Well, excuse me but I thought this must have been a joke.
The only belt I can think of on this machine is the drive belt for the cutterhead and feed rollers.
If that belt is not installed then it isn’t a ‘NEW’ planer.
If there are 2 belts in a bag then somewhere along it’s life someone has been monkeying with it and it is probably not going to keep a belt on because something is seriously wrong with it.
Is it a returned planer and HD is trying to sell it as a new unit?

D_Allen: I always look at the box and this one did not appear to have ever been opened. Nor did it when I opened it. I would never have bought it, if it had been. I thought that it was strange that the belt was not installed myself.

I wonder if I have the right belt because the grooves of the belt are very shallow and it looks like they should be a lot higher for the depth of the grooves of the pulleys. It looks to me like that is the problem. There is really not enough rubber to hold the belt on the pulleys.

I will get with HD on this problem and DeWalt on Monday.
Thank you again.

Do the set-up instructions in the manual actually include the steps for installing the belt on a new machine? If not, I would think that something is not right.

A long time ago I worked retail in the shipping/receiving and repairs end. We were pretty skilled at making the boxes of stuff look like they’d never been opened. Just ‘cause it looks “factory packed” doesn’t mean it is. I’d return it to HD and get a refund or a new unit.

Agreed , something is fishy here.
When I purchased my DeWalt planer , it came with a spare belt , but the drive belt was already installed as it should have been from the factory.
Bring it back and open a second machine right in the store in front of management.

I agree, I have the 734, and the manual says it is set up for use at the factory, an shouldn’t need any adjustments (aside from infeed and outfeed tables) this was true. If you are trying to install the belt, something is not right and this unit did not come from the factory like that. Take it back.
