To ensure that the core is completely cut through, raise the drum and,
with a pry-bar in the pilot hole, gently rock the core back and forth.

If the core should become stuck in the drum, use the holes in the top of
the coring drum to insert a push rod or spud-bar to tap the top of stuck
core, remembering to rotate the drum a quarter turn after each tap. Or
tap the outside of the drum with a rubber mallet.

If the core drum becomes lodged in the roadway, do not attempt to lift
it out using the skid steer it is attached to. This will without a doubt
break of bend the spindle shaft. Undo the four bolts that are attaching
the core drum to the drive adapter and using the steering orbital slowly
raise the center assembly out of the core drum. When the pilot is clear
of the ground you can lift the skid steer arms up to clear the drum. You
can now attempt to work the drum free from the pavement. If all
attempts fail, contact your local dealer and they should be equipped
with a core drum extraction tool.

Check the coring teeth on the drum regularly for wear. You will save
time by cutting with sharp teeth, and reduce the chance of the core
becoming stuck inside the drum, which tends to happen once the life of
the teeth has been used up.
