You need to pull the router from the table and become familiar with the
workings of the adjustment mechanism. Generally speaking, there will be a
locking mechanism and an adjustment collar to set your bit cutting depth.
Unlock, set the depth and re-lock. Re-install in the table and repeat the
process with the router in an inverted position.

I have a Sears router 315.17480. I've never used a router. I have it
underneath my router table. How do I change the height of the bit
through the table? Is it okay if I ask that in this forum? Thank you.
The router was give to me (inherited). I have to rout a dado at a
certain depth. Please tell me also, how do I get the existng bit off?
Thank you again.
