Wow. I wanna kill myself and then a room full of people.

I spent 6 hours assembling this thing, turn it on, the bloody motor runs backwards. They company says I can’t just swap the motor. I will need to return the whole thing.

What a great weekend.

Who sold you a jointer with a head that spins backwards? Gotta know…

I guess I deserve it after buying a Harbor Freight jointer. But even the reviews on here said it was worth it and since my craigslist never has anything but benchtop craftsman that supposedly suck and the next option is basically a $500 Ridgid or Jet -

I just bought the Dewalt 734 as well and was excited to joint and plane some boards. Now I think I might just return both.

Well, a good jointer partnered with the Dewalt 734 helps you make some nice stuff. I’d reconsider.

Have you tried looking for an older jointer or even a newer used one like a Rigid on Craigslist? My nephew bought one for a very good price and it’s working well.

Honestly, I get so frustrated with people constantly suggesting craigslist. I literally check it 2 times a day every single day for the past 6 months. I found a Ridgid one time for $500 (way overpriced considering they probably bought it for $250 when Home Depot was closing out), and a bunch of craftsman desktop.

Craigslist is not an option.

Some electric motors will run backward if you have removed the ground plug and or put an adapter on the plug and stuck it in the socket backward. It’s called reverse polarity.

Well this was a simple wiring job from the motor to the switch connecting black to black, white to white and neutrals to a screw on the frame of the unit. Nothing I could do wiring wise to make it run backwards.

I’m guessing some moron grabbed the wrong motor and put it in my kit. Worst part is they won’t let me just swap the motors. I would have to drag the whole 200 lbs machine back down myself and then spend another 6 hours putting a new one together.

Before you go to the work of hauling it back. Make sure the belt is not tuisted between the pulleys. Not questioning your skil, but sometimes things like this happen.

If it spins backwards you should be able to just reverse the polarity, wire it backwards. Also some motors have a small switch on them that changes the rotation. I have a craftsman jointer I have had for 16 years, it’s a bitch to align when changing the blades but works great once it’s fine tuned, bonus: blades are only $6.

I had to wire the switch on the front myself (a white, black, green from the motor to the switch and then to a white/black/green which is the outlet cord. The neutrals (greens) are both connected to a screw in the frame of the jointer (outside of the switch box) and the blacks and whites are wired across from each other (across the switch). Anyways, when it was running backwards, I said what the heck and swapped the black and white on the motor side (so white was connected to black and black to white across the switch) – no difference.

Pull the small plate off the end of the motor. It may have a wiring diagramon the inside of it that shows how to hook it up for CW or CCW rotation. Good luck.

Half the people on this site are condescending douchebags. Below is a half dozen forums and review sites saying this is one of the good products from HF. I have yet to find a negative review on it (besides my own). I don’t get the holier than though attitude of people like moron – though with a name like that, I guess it should be expected.

No luck on pulling off the end plate. I found where the cord was coming in but there were no diagrams to see what was going where.

douche bag………..thats a nice word, do you know what that means ?……what a douche bag does ?……in layman’s terms it is to “clean a vagina”………….so don’t lecture me on the merits of being condescending.

if you throw mud, you WILL get dirty

it is blatantly obvious, that YOU wired the motor

it isn’t my fault you do not, can not, understand simple schematics.

YOU……are the single reason this “Moron” cannot, and will not, explain to you, what so many have tried to do, and despite the same advice given to you again and again and again………….you think, YOU know something, they don’t, when in fact,…………….you don’t : ))

it isn’t rocket science

call an electrician as they understand and comprehend “polarity”

Some, not all single phase motors can be wired for CW and CCW rotation. Some manufacturers designate by the “lead end” some designate by the “shaft end”. Usually it’s a matter of switching the position of two wires at the motor’s terminal plate. Most times they are “push on” connectors. The info for doing the switch is either at the motor name plate or on the inside of the terminal box cover. The cutter head must rotate toward the infeed table. Hope this helps.

single phase induction motors cannot be reverse by simply “reversing” the polarity or wiring the plug backwards

the motors have two sets of windings, the run winding and the start winding. rotation direction depends on the way these windings are connected to each other.

changing the polarity of either of the windings relative to the other will reverse the motor

under the terminal plate will be a bunch of wires on terminals and a diagram indicating voltage selection(120 or 240) and how to change direction. changing direction is usually as simple as “exchange orange and red wire” for example

I’m uploading some pictures now

I found a diagram on the motor that says To Reverse Inter Change K1 and K2. That is basically telling me to switch the white and black which I have already done a dozen times. But I did it again with no affect. Do you guys see any other way of interpreting the diagram?

I would have to haul the whole thing back to HF and then rebuild a new one (trying to fit everything into my civic). I don’t know if it is worth blowing another day on this thing or just skipping a jointer for another 8 months.

And to Moron – The only thing that I wired was the switch – basic reading comprehension would have told you that.

You can see that the black and white wires are disconnected in the picture. The black was originally connected to the bottom left. The white to the bottom right. They are the black and white from the incoming outlet cord. I assumed from the diagram that reversing those would reverse the motion but it changes nothing.

Thoughts?

From SteveMorris’ post, it would seem that perhaps the red and black (top) are what I need to reverse. Is this worth a try?

Nothing wrong with Harbor Freight. Hey, at least the motor ran!

If it was made in China, well that is on the other side of the world. If you used the jointer upside down, would it then be turning the right direction?

Seriously- glad they worked it out for you. I don’t have a thing against HF, you just have to look at what you are buying, and think about how you will use it. Much of their stuff is of decent quality.
