Kobalt Router Depth Adjustment Skips

Question

I just got this Kobalt router and router table combo from Lowe's. Since I am new to using a router, I thought this would be a good place to start. When I started using it to made some rails and stiles, everything worked great, but now there is an issue with the depth adjustment and I am not sure how to fix it.

There is a hex wrench that you can drop into a hole on the table that lines up with the depth adjustment screw so you can raise and lower the bit. When I turn it to lower, it goes down smoothly, but when I turn it to raise, there is a lot of resistance, and when you get a quarter turn done, it skips, then falls down more than it was raised. Does that mean the router or the housing is defective, or is there something that I can adjust to get it to work again?

Here is a video if the description I gave isn't doing it for you.

Answer 1

There are gears that the adjustment carriage rides on, and you have loosened things too much and the gears aren't properly engaged, and they are slipping.

Because the entire mass of the router is riding on these gears it is typical with routers mounted upside-down like this that you have to support the body of the router by hand when adjusting up. And the adjustment isn't quite a binary locked/unlocked arrangement. I suspect you have to back off the lock enough to allow free movement of the gears, but not so loose that they skip teeth. Some routers have a positive lock that you engage after you've adjusted the depth with or without an adjustable gear arrangement.

Also, note that there is a different between coarse and fine adjustment. You would adjust your coarse depth to a "0", and then use the fine adjustment to get your final depth. I suspect the coarse adjustment is the one that needs that sweet spot between locked and loose enough to turn without skipping gear teeth. Check your owner's manual to be sure.

Answer 2

I had the same issue. It was not the worm gears. My plunge was getting into a bind and caused some wear marks on the router which was causing the issue. I used my Dremel and lightly sanded down some of the groves caused from the plunge. Then used white grease to lubricate the router and works great again.
