Hell everyone, I recently purchased a Shop Fox table saw and was hoping to get some advice from others who may have experienced issues with their Grizzly version of my saw (G0690/G0691). The blade height adjustment wheel is extremely difficult to raise and efforftless to lower.

I have cleaned the gears and coated them with white lithium grease and have seen zero improvement. I’m really hoping there is a fix (within my means) because I have so much time invested in the assembly and allignment of the saw. I would be bummed if I had to repeat all that with a replacement machine.

There is nothing obviously binding but then again it’s difficult to see without removing the top and yes I loosened the knurled locking knob…

Have to called Grizzly tech support? They may be able to point you in a direction.

I have a 690 and have no trouble raising or lowering the blade. It is harder to raise the blade, because you are lifting the motor and 1/2 of the trunion, but it isn’t hard to raise and it isn’t binding.
I wouldn’t use alot of grease, just because it will attract all the sawdust to it.

Hey Steve, thanks for commenting. I literally just uncrated and assembled this saw so it hasn’t seen a lick of saw dust. There is plenty of grease on the gears where they mesh. I get that the blade would be more difficult to raise but something is definitely wrong here.

I did contact shop fox and am awaiting action from them. It’s just really disappointing that I’ll likely have to swap this machine out with a new one. I just finished waxing the top!

There are metal shavings that are piling up beneeth the aft trunnion where the height adjustment shaft terminates.

That’s definitely not good. Worm gear not deburred maybe? Shot in the dark.

The worm gear appears to be good to go. When lowering the blade the first 2-3 revolutions are just as difficult as when raising the blade then suddenly the binding noise stops and the wheel turns effortlessly. Its very difficult to determine the origin of the binding but I swear its the gear mesh. However, the metal dust is coming from the bushing at the aft trunnion.

It could be my bad eyes on a 40” monitor but that looks like paint not metal to me.

It looks like the shaft bearing may be rubbing on the trunion. I think it is held in place by a allen screw. see if it is rubbing on the cast iron. it may be too tight.

Just looked at the parts breakdown and it shows two copper washers installed on either side of the bushing in the trunnion. I’ll tinker with it tonight and see if something is installed wrong.

Update, I recieved a call from shop fox customer support and they explained that the nut at the end of the height adjustment shaft can be backed off and will allow more freedom between the gear mesh. Fingers crossed, I will try this first thing when I get home.

@RibsBrisket4me

The experience has been a little furstrating but probably because I don’t have a lot of patience. They did respond in good time and were very pleasant. I have an entirely seperate issue with the fence that has been documented in my review of the Shop Fox W1819 on Lumberjocks. There are some quality issues that really bug me and I feel like I got the runaround on the phone today regarding those issues. I will give all the details on that later tonight. Bottom line is the saw has the potential to be awesome but comes with minor issues. I personally don’t feel that after spending $1500 I should have to take things apart and reinstall them as they should have been in the factory. As for the fence it doesn’t sound like they will replace it so in short I may have to pick up some of my own metal stock and fix the defective parts on my own.

I totally understand your point of view.

The shaft sounds like an easy fix. The fence hopefully so.
I just hope that it does not ruin the enjoyment of your purchase.

You got a great saw.

Just be aware that once you get things working right, you will experience the same difficulty with raising the blade once all the saw dust gets caked in there. I’ve yet to find a decent solution other than to use my air compressor to blow out as much as I can from time to time.

I’ve read that some folks clean off all the grease and brush on some paste wax. The paste wax dries hard and shouldn’t attract as much saw dust. You could also try spray on Teflon.

Update#2, loosened the suggested nut and no improvement at all. I backed the nut off gradually until the point of stupidity and it had zero effect the the hand wheel. I could still hear the gears binding…Wonderful. I guess I’ll remove the entire assembly and see where that goes.
