Morning all. I have a General Int. 10” cabinet saw model # 200 MR. It has developed an issue when I try to lower the blade. The blade will drop maybe an inch (but it is quite jerky as it goes down). After the first inch it gets harder to lower, till it finally jams and stops. Raising the blade just a tad will allow me to drop it further then it jams again. Repeat operation several times and I get it down. Coming from the screw mechanism I’m sure. I’ve ben in there with the compressed air, brushes and silicon spray to no avail. Any thoughts or tips would be great.
Thanks you.

Just curious as to how old it is? Have you also inspected the pivot point to see if the shaft and bushing are worn or need cleaning and lubrication? I did have a similar problem on a very “experienced” saw many years ago, and the pivot shaft assembly had worn to the point where there was enough play that debris could get in and cause problems. Just a thought.

Have you tightened the height lock?

Mark, you might call General to see if this is a known issue or if they have any suggestions. Let us know the resolution.

Clean and lube – preferably a dry lube or wax (paraffin). Compressed air won’t do it. Solvents will. It doesn’t take much build-up to cause problems exactly as you describe.


PS: You may be to the point where a partial disassembly is required to get to everything – those trunnions and other bits are difficult to reach from below. Taking the table off will help a lot and it’s only 4 bolts.

Druid. It’s about 4 yrs old, moderate to light use.

MadMark. Height lock ( I assume you mean the bolt that stops the whole assembly when it reaches the bottom) is tight.

Hey Art. How goes it. That’s not a bad idea. I did call the place where I got it from, but the youngster on the other end had no clue.

MrUnix. I did use a silicon lube but with no joy. I’m thinking’ I’m at that point as you said….Durn!

Thank you for all the feed back gents. Always a pleasure.

Height lock – center knob in blade crank. They drift.
