I have another post on here about how I purchased a Jointer on Friday, assembled it and turned it on and the motor runs backwards (blades spin counterclockwise). I was a little disgruntled at the time (6 hours of putting the thing together and then about to joint a board and this happens can do that to you), so the conversation got a little off track. I wanted to create this topic to address the wiring of the motor specifically to see if I can still save this jointer.

This is a HF 6” jointer and they need the whole thing returned (meaning hours of setup on a new one) and will not just swap motors.

I opened the motor plate where the wires come in from the outlet (this is a 110v motor). The pictures below show the wiring. The black and white go on the bottom left and bottom right. I attempted to switch them as it appears that is what the diagram (in the picture) shows when it say “To reverse inter change k1&k2.” There is no change in the motion of the motor when these wires are swapped.

Would swapping the wires in the upper right and upper left have any affect?

Thanks for the help.

If you can’t get this motor running right, just go buy another jointer, swap the motors, and take the unassembled one back, with the bad motor in it, and tell them, truthfully, that the motor turns backward, and get a refund. I’ve thought about the ethics of doing this, and I’m OK with it. You’re not getting anything you haven’t paid for, and by bringing it to their attention, you’ve done your part to make sure the next buyer doesn’t get the bad motor. What it will cost you is an additional trip.

Also, what does the note say? To reverse, inter-change (??)

The note says To Reverse Inter Change K1 and K2. K1 and K2 are not labeled anywhere but based on the orientation of the wires and the diagram, it appears to be the bottom left and bottom right. Those are the two (black and white from the outlet) that I tried switching to no affect.

That is a great idea. The tough part is that I only have a Honda Civic (I borrowed my brother’s truck to get the first one) so I could not buy one and bring it home, swap the motors and bring it back…

Thoughts on the ethics of this:
Bring motor with me. Buy new jointer. Open package and swap the motors. Bring jointer right back inside. Say the motor runs backwards and return.

Except you won’t know for sure whether that motor turns the right way without testing it.

I suppose you could remove the cover on the new motor and compare the wiring.

I do not see how you can change the direction of this motor can you take a pic of the tag on the motor?

Does this motor have a capacitor on it? Is it correctly installed?

SWITCH THE LEADS THAT GO TO THE MOTOR WINDINGS. NOT THE POWER SUPPLY LEADS. PUT THOSE BACK WHERE THEY WERE ORIGINALLY. If this does not change rotation, take the motor back to the store and DEMAND a replacement!

I finally got a hold of a person at one of the HF’s by me. He said it was no problem for me to bring the motor in. Brought it in (easy to take out of the jointer) and swapped it. Tested the new one before it went in – ran the correct way. Checked the wires out of curiosity and the red and black (on the top row) are in opposite positions. Whether or not that is the reason, who knows. They may have just used different color wires.

Either way, I set it up, ran some boards through – thing is buttery smooth. I am definitely happy this worked out for me. Now it is time to set the planer up too!
