Thread: Table saw stuck (nearly)

I find removing the saw blade gives you a bit more access to the worm gears that are responsible for up and down movement of the blade. Give it a good clean with compressed air and a wire brush. I believe the problem is caused by saw dust being trapped between the gears and gradually being compressed further by winding up and down, forming a hard crust which jams the gears. Once cleaned, you will see the movement coming back. I don't see the need for any lubricants. In fact, it will make things worse if the gears are not completely free of saw dust.
Are you using dust extraction on your table saw?
You may also look to find ways to improve the under table extraction or it will jam again in the future.

Needs to be well cleaned to remove all dust. Graphite powder works wonders.

Hey just out of curiosity does the locking screw in the middle of the up/down wheel feel normal when you turn it or is it stiff to move?

This could be the common problem that has occurred with several Harvey owners .... the problem is in the worm gear rod ens ... hard to explain ...but here goes. Open up the cabinet door on the left (motor) side. You will see a rod for the worm gear that goes from the crank handle to the back of the cabinet. At the back end of the rod there is a round locking ring and a holding bracket. The end of the rod has a large nut. Between the locking rig and the bracket there should be a couple of copper washers. These sometimes get mashed and find there was into the axle part of the holding bracket. You need to clear the copper washer out if caught in the holding bracket and reset the locking ring (need allen key). Regards Rob


Have a look at page 79 in the owner manual (Harvey is the same as Grizzly 0690) The parts are 119 to 122.

You're dead right Rob. I rang the place where I bought it and he said the same thing. Since my initial question i stripped it again. Loosened that locking ring you mentioned moved it a bit, I think as it was very tight. Gave it another clean, wire brushed the trunnions and blew all the dust I could see. Put everything back and tried it and I think it's about as good as I can get. I can turn the wheel up and down one handed and I think that's a pretty good result.
I also filled as many air holes as I could see to help with the dust extraction. I also stuck some wind stop strip along the the door opening which really sealed quite well. I'll also be having a six monthly clean out and also use the dusty more often. And to be honest I didn't switch the dusty on every time I used it. Ah she'll be right but a few "She'll be rights" amount to a lot of sawdust. It's going into a outside shed soon and a mate is going to set up a remote switch which will make things a bit easier.

Thanks to all for replying it's much appreciated.

I am thinking it is not good idea to seal off all the air holes. you need more available air to replace the air being extracted by the dust collector. On my Laguna Platinum I opened up the cabinet hole from 4" to 6" and cut a hole in the door opposite about 1.5 times as big. the result is that there is absolutely no build up of dust in the bottom of the cabinet.
