My Grizzly 8inch came friday and I’m very excited… The freight company was a little disapointing, but I was pinched for time cause of work as well as the people who came to help me. In the end I ended up unloading it myself while the driver watched all because he was over 2 hours late. But I was still happy cause I had my jointer and was only a few minutes late for work.
Anyways, now Im setting it up and I think that the manual is less than perfect, but it probably has a lot to do with my very small amount of mechanical experience. So, if any one can explain to me better than the manual about how I can tell if the set screw holes are aligned with the countersink holes in the gib, I would be grateful. I stuck a light in the hole but still can’t tell. The manual said to tap the gib with a screwdriver but that has 0 effect. I’m guessing that it doesnt need any adjuctments now anyways, but in the future I would like to know how to tell if the the holes become misaligned. I also wasnt a big fan of the pulley alignment task because they deffinitely were not aligned and loosening, aligning, and tighting while holding the alignment proves to be a difficult one man job.
I still dont have a 220v outlet yet but I did notice that the motor can be wired for 110v, there is a diagram on the motor cap. There is not one for the switch however. Since I dont know much about electrical, can someone tell me if it would be smart to wire to 110 or wait to get 220.
I greatly appreciate any advice on the setting up and electrical.
Did I mention I am very excited to try it out.!!!

As far as the electrical is concerned you probably don't need to rewire the switch(at least I didn't on my Delta DJ20) but be careful to check the the motor is turning in the correct direction if you rewire for 120. My motor switchplate diagram would have had the motor running backward but the instructions in my manual were correct. I called Delta for clarification before I rewired.
So you're saying that if I rewire the motor to 120v, that should do the job. What are the disadvantages of doing this ie... lack of power, draw too many amps??? I only have 14-2 romex with 15 amp outlets in the garage now.
I also went to "The Depot" and picked up a 250v 30 amp plug for the machine. I figured its ok that the amps and voltage are more but not sure though.
Thanks for the info Ron.
Running a motor at the max amps from a 115v circuit could cause excessive voltage drop; real bad for motors. Using 220 cuts the amps in half, doesn't't save any $ on the electric bill like many think but does minimize voltage drop which has many benefits. What are the nameplate amps at 115v? Do you have access to a volt meter and know enough to use it safely? If so you can run the machine temporarily on 115v and see what the voltage drops to. Anything more then a 10% drop will shorten the life of the motor and result in less then max performance.

If I remeber right the amps at 115 are 18 and 220, 9. I would like to have the motor last so I wont try any rewiring unless I am certain that it is ok.
As far as the gibs... The manual said to remove the lower gib scre and make sure it is aligned with the countersunk hole in the gib. Seemed so but I am not certain. I ended up just leaving it alone for now.
If you have the G0500 that pulls 24 amps at 110V. Do NOT run it on 14 GA wire or a 15 amp breaker! Even at 220V I would pull 12 GA wire and put in on a 20A breaker.
Not sure what you are saying about the gibs & set screws, but mine came dialed in and requires very little care except for knife sharpening - I have GOT to stop running old recycled wood through it!
As always your MFG manual will be the final determination as to if you have to replace the switch. Best bet is to call Grizzly and ask them. On a properly installed circuit there should be no performance difference between 120 and 220. Because I am going to move in a year or so and had a 20 amp 120 circuit available I elected to rewire my DJ20 for 120 and that turned out to be easy.
I will install and use 220 whenever I finally move but for now the 120 serves me fine. It appears that the Grizzly needs a bigger circuit then my DJ20 so that might have a bearing on if you can get away with using the 120 service you currently have. If you have to upgrade might as well go 220
I don't know about Delta, but the three 8 inch jointers currently in the Grizzly catalogs come with 240V-only magnetic switches with thermal overload for the motor. If you switch the motor itself to 120V, a new magnetic switch from Grizzly runs about $50.
The switch on these jointers include the motor overload protection function, which is why it works on 240V only. If you re-wire for 120V, you need to buy a new switch from Grizzly (or elsewhere), sized for the current draw at 120V for the HP of the switch.
Now, at 120V, that's alot of current. it would need its own circuit, anyway, and upsizing the branch wiring to reduce startup voltage sag wouldn't be a bad idea. But if you need a new branch, anyway, 'might as well do it right and put in a 240V one. You won't need to buy a new switch for the jointer, and you can use smaller-guage wire.

Thanks for the advice Barry, I think that I will end up spending the cash and getting a subpanel in my garage. Seems to be the smartest thing to do.
Go for the 220 if you can... You could also ask the electrician to make you a outlet box you can plug into the 220 when not in use for additional 115 outlets.. I think they will make you one up.. Cost?? Not sure... But comes in handy.. I made my own so it was just material cost...
In regard to your changing the motor to 110 insted of 220, I bought a grizzley motor about 2 years ago 2 hp it was wired for 110 ,I wanted it 220, there were instructions on the cover plate but they were about as clear as mud. I finiley took it to a guy who rebuilds electric motors, After about an hour of messing with it we did get it changed to 220.That clear as mud was the electritions coment when he read the instructions on the cover plate.
Have a nice day Lee
My suggestion would be to call Grizzly. Their techs are very friendly and have lots of patience. They will literally talk you through all assembly issues. When I was assembling my BS I had the guy on speaker phone right in my shop.
